Subject: welcome to qv-interest

Well, the initial flood of requests have subsided, so I guess we're
open for business.

The list is an e-mail reflector -- no human involved.  This might
eventually mean you get a "can't deliver to ..." message from some
mailer when you post.  If you get one, please send it to me and I'll try
to take care of it.  Eventually (as work permits) I'll get some
mechanisms in place to prevent this kind of message from reaching you.

There are 29 names on the list ... apparently all Quadvraverb owners, or
soon to be.  Most are in the US, but there are a number of "foreign
correspondents" as well.  The distribution between educational and
commercial sites seems to be about even.

As my note only went out to, I suspect many people
who would benefit from this list did not see the announcement.  Feel
free to pass the info along.

      Greetings. I am also curious about the number of readers for this group.
   Perhaps you could post a summary. A directory of all of us could prove to be
   very useful.
      Some basic biographical information about the readers might be worth
   knowing as well; mainly concerning their involvement with music and what
   kind of use they get out of the quadraverb. So, to get the ball rolling,
   I'll give a brief bio.
      I work as a customer service support engineer for Mentor Graphics full-
   time and play keyboards on the weekends. So far my use of the quadraverb 
   has been limited to the factory patches. The equipment I use consists of:
      (*) Ensoniq ESQ1
      (*) Yamaha  TX81Z
      (*) Alesis  Quadraverb
      (*) Alesis  HR16
      I'll stop my rambling for now. Thanks for the email and hope to hear
   from you again soon.

   P.S.   Rex, I am replying to the interest group and also to you directly 
     because I am curious if your mail path will work for me or not. If you
     receive this directly from me, and have an extra minute, please let me
     know it reached you. Thanks

Subject: mix levels

A trick I use to get cleaner sound from the QV is to boost the mix
levels to their maximum values, while keeping the relative volume
between the effects constant.  This means I can get a really wet mix
without cranking the effects sends on the mixer to the point where the
hiss in my gear is noticeable.  What I wonder is why Alesis didn't do
this to all the patches in the first place.  I'm converting them
as I use them.

Well, it depends on what you have in mind.  A good reverb patch for
"Warm Pad Fade" on my D-10 will probably stink to high heaven if you use
it for acoustic guitar.

So, are there a lot of guitarists in here?  I know there's at least
one (Hi, Dave!).  Or are most of you qv-interest readers trying to
breathe new life into those cheesy horn patches you never had the heart
to throw away?  I'm a keyboard and drum man myself.  Unfortunately,
acoustic drums are out of the question in my apartment building.

Well - at least one more guitarist (me)..

I bought the QV after owning an SPX90, and then trying out most 
of the stuff that's currently popular (digitech, Yamaha, ART, and
Roland). The QV seems to be a great bread and butter unit for guitarists.
Sure, it doesn't have _real_ pitch shift (gawd.. the ART SGE had GREAT
pitch shifting), but the pitch programs (flange, chorus, phase, detune) are
among the nicest I have heard.

For subtle guitar effecting, I think the QV is near impossible to beat, 
especially in the price range. I usually use a light delay with some EQ
or reverb. On those configurations that don't allow reverb, I use an
outboard MIDIverb II (which I also love to death).

As soon as we figure out how to do QV patch postings (SYSEX (yay)? ASCII (boo!)),
I'll post a few of my guitar patches...

Subject: QV SYSEX

In reference to Pete Lyall's wish to trade QV patches in SYSEX form
rather than ASCII, I have a program called YLib that is a patch librarian
for the QV, and read/saves data in the SYSEX format.  BTW, it also works
with the DX7II, TX81Z, K1, P3, D-110, and GR-50.  It's for the Mac.
If anyone wants to use it for their QV, I'll send them a shareware copy.

I write network management software during the day (and many nights &
weekends, sigh).  Like Dan, I also have TX81Z/QV/HR16, but I use an old
Korg Poly-800 when I need a keyboard (I'm a drummer at heart).  I use an
Amiga as a sampler, synthesizer, sequencer and patch editor/librarian.
The Amiga L,R outputs are hooked into my mixer, and I use the Amiga
samples via the musical keyboard or under sequencer control.

Most of my use of the QV has been for enhancing the HR16 sounds.  I
haven't created any new patches, just tweaked the ones from the factory.

Some time ago I decompiled the QV MIDI SysEx information - both command
and dump formats.  It was posted to, almost a year ago.
If for some reason you didn't get a copy, you can get it via anonymous
FTP from in ~ftp/midi/doc/quadraverb-sysex.Z (I think, this is
from memory) or let me know and I'll email it to you.  For those of you
who have seen it, it hasn't changed since posted except to update my
email address and phone number.

Whoa there! First things first - there's a freebie engineering change
that Alesis will put into the unit. I also noticed a horrible whine
when an EPS was plugged into the mixer. Contact your dealer. Again -
it should be a no-charge update.

Secondly - the only time I've ever heard of a noisy QV was when
someone tried to use a microphone or guitar directly into the unit,
instead of using a line-level feed (like a mixer effects loop).

I have had LOTS of rack effects pass through the gates here, and the
QV is among the quietest. Have the mdification done and see how that
affects things.

There is no Hi EQ Bandw under the 3bandEQ->Reverb configuration.  There
is under the 5bandEQ->Pitch->Delay, but then the reverb is gone.  I
ignored the bandwidth setting here.

I just noticed the name of the patch today.  "Big Snare".  Humph.  I was
trying to play piano through it last night... :-( :-)  It was a bit dull
but I liked the big sound.

Subject: A noise problem

I recently altered my system, and in the process have gained a buzz noise
when using my guitar with any patch that uses the PITCH DETUNE section of
my QV.  I think I might be a candidate for the QV input filter mod.  Here's
why I think so:

Hese are some ways I can reduce or eliminate the buzz:

	1) Turn guitar volume all the way down.
	2) Touch any metal part of the guitar.
	3) Reduce the PITCH DETUNE AMOUNT to zero.
	4) Reduce the PITCH MIX to zero.
My system used to look like this:          ||

Notice that the EPP-400 is no longer in the system.  This was made possible
by the purchase of an MX-8 Midi Patchbay/Processor.  Here's my theory:

I think the guitar's pickups are responding to the high RF level in the
room (there are at least 10 CPU's within 15 feet!), so turning the guitar's
volume down eliminates the ultimate noise source, and touching metal makes
the guitar a less efficient antenna.  This RF energy didn't used to get to
the QV because the EPP-400 blocked it, but now, without the EPP, enough gets
through the MB-76 that when using PITCH DETUNE, an aliasing condition results
in the buzz.

If the above is correct, then I feel that the input filter mod for the QV is
in order.  What do you think?  Does one have to send the unit to Alesis for
the mod?  Note that I am handy with a soldering iron, and if it's just a RC
or two, I could deal with it (if I knew what the mod was!).

Thanks for any help you can provide.

Here's a collection of a few of my (original) favorite patches for the
Alesis Quadraverb for use with guitar. They are in an ARC file that
includes a 'readme' for suggested applications, and 6 or 7 individual
SYSTEM EXCLUSIVE patch dumps. These may be loaded back into the
quadraverb with any old SYSTEM EXCLUSIVE utility. They load directly
into the EDIT BUFFER, and thus will not clobber any existing patches
unless you store them. Enjoy them, and let's see more of them!

Subject: Quadraverb MIDI hangups

I spent a couple of bloody hours last night trying to make my M1, QV, JLC PPS-1
and PC work together in peace and (subjectively) harmony.  Learned a few inter-
esting things that may save some people some time.

I have these 4 MIDI gadgets (including the PC with MPU-401 interface), and had
them wired up more or less serially: (in my notation, -> is out, --> is
THRU)  PC->M1->QV-->(THRU on)PC.  Life was moderately cool.  However, the M1
seemed to filter out all SYSEX info, so I couldn't load patches to the QV.
What's more, the QV seemed also to filter SYSEX, so I couldn't dump from the
M1.  Plus, to the the tape sync box (the PPS-1) into the loop, I had to do yet
more plugging and unplugging.

So, I bought a couple of Pocket Merge's and a Pocket Thru.  Now, the Thru box
is connected to the OUT of the PC, and provides 3 feeds: to the M1, the QV and
the PPS-1.  Great.  Then I merged the M1 OUT and the QV OUT together back into
the PC.  Great.  WAIT!!  What's that noise!  Why is the M1 locked up!!
Forgot to turn off THRU on the QV (in the MIDI section).  MIDI loop.  Big

Okay, that's cleared up.  Now let's see if the tape sync box still works.
Nope.  Lock light goes crazy, noise everywhere.  I have its output merged now
with the M1.  M1 is locking up and going crazy again.  Read manual.  Manual
sez "PPS-1 OUT's are merged with its IN".  Disconnect the PPS-1 IN (coming from
the Pocket Thru).  Everything seems to work.

One of the strange effects of the MIDI loop created by having the QV's THRU
setting ON was that the QV was really freaking out when I tried to change the
program.  It would change one or two programs in either direction from where
it was, but then would start erratically flipping among the previous two or so.
Of course, now it all makes sense: pushing the "value" button in "program" mode
sends out a "change program" midi instruction, which gets looped right back into
its input.  Yikes.  All in all, the thing seems pretty fault tolerant.

When I opened the box to my recently acquired Alesis MIDIverb III, I
noted the absence of the familiar 'rep' card which shows the program
name assigned to each patch number. I called Alesis technical support
and they indicated that it was not ready at release time, and that
they elected not to hold up shipments for a simple plastic card. The
rationale was that they would send them out as warantee cards arrived.
I asked if they could FAX me a copy, and they happily complied. Here's
a listing of the 100 factory preset patches
in the MIDIverbIII. I hope you find them useful!

Lots of people have been pseudo-flaming Alesis for leaving the Master
effects volumes on the Quadraverb at around 50 instead of 100.  They
indicate in the manual, (RTFM, remember?) that if one is using a mixer
and piping the effects through the 'verb on the effects bus, and
mixing it in with a dry signal on the board, crank it up.  If,
however, you send your only keyboard, or a mike, or whatever right
into and out of the 'verb, keep the level around 50, or you'll loose
too much of your dry signal.

Just thought I'd clarify.

Oops.  That should have read, "Keep the Master Effects level *and* the
Direct Signal level at around 50 each."  If you use it just for an
outboard effects processor, then push the Master effects level up to
100.  Hmm.   I forgot how the EQ signal gets handled, but if you are
only using EQ, I think you set the DIRECT SIGNAL to be PRE-EQ, set it
to 0, and boost MASTER EFFECTS level all the way up.  Either that, or
you set DIRECT to be POST-EQ, crank MASTER EFFECTS to 0, and DIRECT

I think both ways will work -- I'll have to check it out!

I just got off the phone with Alesis.  RSN ("in a week or two") they
will have an upgrade PROM available for the Quadraverb.  The new PROM
will add the following features:

	- 1.5 seconds of sampling.  Once sampled, the sample can be
	  re-triggered (via MIDI), can be transposed over a two
	  octave range, etc.  It can't be 'downloaded' to your sampler.
	  The guy I spoke with stressed that this is just another effect

The upgrade will cost US$30, and will *probably* only be available

Alesis claims the QV SysEx info is available from IMA (International

through the IMA.  They have no idea *when* that will happen, however.

Good question.  Probably via chords or some other "creative" method.
I suppose we'll all find out soon.  I'm more interested in finding out
how they mess up the SysEx info, and I certainly hope they provide
some way of determining the PROM version number, so patch editors can
present the correct interface to users.

Certainly.  However, this is *not* "top-secret eyes-only" information.

My guess is that they won't change the internal format. More specifically,
the new format should be a superset of the old, so that it will understand
old-version sysex dumps. Why? Three reasons, mostly from common-sense: 
1) lots and lots of QV owners would be dismayed if they lost all their 
existing data after the upgrade, 2) it would mean more work for Alesis if
they had to reprogram all their old factory patches, 3) when a similar 
upgrade for the DigiTech DSP-128 came out, it was reverse-compatible with
the old version, and if DigiTech can do it, Alesis must be able to, too.

At least I HOPE it's gonna work this way. :-)

The memory locations in the QV already do double duty depending on the
configuration.  For example, bytes 0-12 are used for the graphic EQ
when the graphic_EQ->Delay configuration is on, but in the other
modes, those locations are used for the Low/Mid/High bands of the
parametric EQ.  As long as they invent new modes ("gee I'm in mode 5,
so interpret the bytes *this* way") they can add lots of new features
and never have a problem.

So not to worry, your old sysex dumps will probably be compatible.

Yeah, that's pretty awful. The effect I think we're supposed to be hearing
is something like five bandpass filters with fairly high resonance, rather
like five bands of parametric EQ, only more resonant. I haven't played much
with the resonator configuration yet; I think I'll have another go this

I'm not Bob, but yes, spaced out is one way to say it!  I set out to do a
GLIB version for the QV and gave it up.  The way GLIB works one would have
to pretty much rewrite the "synth" specific portions to support the way

  I went back and reset every parameter I could find, including the MIDI
channel on the Qverb and the resonators seem to work now.  They act sort
of like high resonance filters, but they seem to be more 'dynamic' in
response to input volume than analog filters I have used.  If I play a
piano patch softly, the effects from the resonators is inaudible, but
when I play loudly the resonators pin the clipping meters.

  I don't know what I did wrong before, but the MIDI GATED mode seems to
work.  If you don't use MIDI GATED mode, the resonators are fixed tuned to
the semi-tone offset (default 0 == middle C) I think.  You might try cranking
up the resonator decay time and see if the clicks stretch out.  I'll try to
get a SYSEX dump of my resonator patch and post it Monday.

Well, I got my resonators to work with MIDI GATING. I don't know exactly
what my problem was, but I did discover that the resonators seem to be
velocity sensitive, which I didn't expect (the manual says nothing about
this, and the term "gated" doesn't particularly suggest velocity sensitivity
to me, but hey, we've already bashed this manual before). It's posible I
just wasn't pounding the keys hard enough to get the proper effect. Anyway,
it works, and I like it.

Also, I recalled all the factory programs on the assumption that there might
be some new ones in the new ROM. There are, but only 10; they're at locations
80-89 if you're interested in checking them out (you can just pull up those
programs, instead of dumping your whole memory, like I did). Mostly they
use the multitap delay, but there's one each for the auto-panning, tremolo,

I assume what you mean is that the sample sounds like, well, sh*t compared

A single program has 128 bytes of data.  When it's encoded and shipped
over MIDI, it's 147 bytes (without SysEx headers).

A full dump is all 100 programs, end to end.  The edit buffer is not
dumped on a full dump.  No MIDI parameters are ever dumped, and there
is no checksum information.

No problem with full dumps; they will be under 15K (unencoded).

This information came from the Quadraverb sysex document, authored by
yours truly.  The QV and QV+ do dumps the same way; just that some of
the values in the QV+ dumps are different, and some previously unused
locations are now used.

I've had some problems with full dumps; some devices can't handle 15K
of data at MIDI rates without dropping some bits.  Since the QV
doesn't send checksum information (and most generic sysex
devices/programs don't honor them anyway), I've had best results by
shutting off all other midi traffic (that includes disabling active
sensing on stuff that uses it), directly hooking the QV MIDI OUT to
the other device's MIDI IN (don't use intermediate devices) and
dumping the bank two or three times.

I agree this shouldn't be necessary, but relying on just one large
dump across an active wire without checksum information is foolish for
data that you really want to keep or can't reproduce easily.

you have to feed back the signal, so a single "THUNK" (that's me

I'm talking about the multi tap).  It doesn't
happen that fast, though, if you set the parameters carefully, but in
the end the original signal has disappeared: the Quadraverb has
transformed it to synthesizer-like hum, which can go on for ages

you make it a 100?

Subject: Interesting QuadraVerb behaviour

I wrote a sequence this weekend that relied heavily on a Leslied organ
sound, so my QuadraVerb's Leslie simultator got called into action.  Along
the way, I discovered an interesting anomoly in the behaviour of the
QuadraVerb to report, and see if anyone out there knows more about.  I
should point out that my QV is an original version, not upgraded to Plus.

To allow the sequencer to have full control of the QV, I assigned the
following controllers under the QV's MOD menu:

	controller 12 - Leslie Speed
	controller 13 - Leslie Motor
	controller 14 - Leslie Hi Level
	controller 15 - Effects Mix Level (which is master level for
			this configuration)
In the MIX menu, I set the Effects Mix Level to zero, so that the
controller has complete control of the output level.

In the sequence I set initial conditions with the following events:

          Trk  Ch   Time
        >  15  15      2:01:014  Patch    39            < select patch
        >  15  15      2:01:049  Contrl   12 127        < set high speed
        >  15  15      2:01:050  Contrl   13 127        < set motor on
        >  15  15      2:01:051  Contrl   14 127        < set full hi level
        >  15  15      2:01:052  Contrl   15  75        < set initial volume

Note that each controller event is just one tick later than the previous
controller event.  Under these conditions, the QV would OCCASIONALLY seem
to miss the controller 15 message and sit there in the zero gain condition.
(It was at zero gain because the QV resets all MODs and assumes the MIX
levels upon reciept of a patch change.)  I found I could get it to work
reliably by setting initial conditions as follows:

          Trk  Ch   Time
        >  15  15      2:01:014  Patch    39            <
        >  15  15      2:01:049  Contrl   12 127        <
        >  15  15      2:02:000  Contrl   13 127        <
        >  15  15      2:03:000  Contrl   14 127        <
        >  15  15      2:04:000  Contrl   15  75        <

Note that there is now a greater amount of time between controller events.
This would seem to imply that the QV has a limit to the rate at which it can
receive and process controller events.  I experimented with changing the
tempo, so as to alter the time per tick, but could not seem to find a
corelation.  I did find that if I enabled Cakewalk's Patch/Controller search
back function, and started the sequence from other than the start, the volume
would come up zero every time.  This would seem to indicate that Cakewalk
(v3.0) outputs what it finds as fast as it can, and would therefore provide
the worst case condition for this problem.

the "thru" midi jack of the quadraverb.  Now I just make sure the

keep it on its own branch out of my controller (i.e. Don't have any

I have been controlling my QV using my DX7IIFD, using the two control sliders,

I have noticed:

obnoxious levels of "zipper" noise occur when changing the delay time
settings. and that is only when there is input to the delay, so if i 
change it when i am not playing it is not a problem

it is quite easy to set the levels too hot for either the QV internal (the
mix levels, i.e., reverb out, delay out, effects out, etc.) and this causes
ugly distortion.  the only cure is to set the range of each modulator so
that you avoid a combination where the mix levels are too hot.

I have not seen the trashed disply syndrome, as it is mounted in a rach and
i never look at the unit during performance. i do send it a fair amount of 
information, between aftertouch, mod and volume controls. i will try it at

I don't think the QuadraVerb is the only machine with this problem. If you
think about it a bit, there's really no way to modulate the delay time of
a digital delay without chopping up the delayed signal. Well, you can do
it by changing the sampling rate of the delay, but that causes the pitch
of the delayed signal to change (you can hear this effect on older units,
like the DigiTech RDS series) and gets into other problems, like changing

I mix for a country/folk/bluegrass/rock band and use the QV+ 
exclusively for vocals. It is capable of some very dramatic effects,
but I stick to really subtle stuff for this kind of music...

I think the "MULTI-VOCAL", "PING-PONG DELAY", and several of the
"MEDIUM-ROOM" reverb presets are good for subtle vocal enhancement.
Here are some of my observations from 'experimenting':

1) if you use the QV+ through a mixer, set the dry mix output to zero,
and the wet mix output to 99. (You can mix the components of the
wet mix separately--a great feature)

2) pick delay times that match the room you're playing in. I use
settings between 12 and 100 mS mostly, but a 200-300 mS delay
very low in the mix sounds good once in awhile. A 12 mS delay will
give a vocal alot of presence...and the midrange of the wet signal
might need to be EQed down for a "pleasing" effect. 

3) in a small to medium sized club, a stereo delay (e.g. L=42, R=46)
that is fed to a mono mix sounds good. I don't use alot of reverb--
it doesn't sound natural. But if you do, match the pre-reverb delay to
the room-size (~ 1 mS per foot). 

4) start out with the EQ flat, and take the delay and reverb inputs
from the "PRE-EQ" feed. Once the sound is in the ballpark, you can 
go to "POST-EQ" inputs and tweak the effect.

5) a standard trick is to boost the volume or the delay time of
an effect (e.g. during the chorus) to vary the `punch' of the vocals.
An even better way to do this--use stereo chorus (with 8-15% feedback)
underneath the delay. Keep the chorus real low in the output mix for
the "normal" sound, then sneak up the chorus in the wet mix for effect.
It sounds better than varying the delay time.

Hope this helps...I'm still learning what the QV+ can do, and haven't
had alot of luck with the multi-tap delay or gated-reverb. Any advanced
QV users out there who have mastered these effects?

1. I've tried using the pitch transposition for it's name, but the transposer

   question is: Is it possible to get a decent 12-string sound? How does
   the pitch transposer really work?
2. Does anyone have a MIDI foot switch? On the Alesis, the 1st setting starts at
   00. Most footswitch's don't have 00, but start at 01. I've tried setting
   the correlation from 00=00 to 00=01 and so on...Otherwise, I have to re-

Thanx for responding and if you have any other pieces of info, I'd be glad

By-the-by, I used to have an ART/SGE and really loved the 12 string sound
(as well as the 5th up) but didn't like the tin sound. The QuadraVerb has
a much better sound for guitar in my opinion. Do you have any info on the

Today I was trying to recall an old factory preset (patch 81, "Rough

happened was I got some new presets when I updated my chip to the
Quad+.  This is great, because I get some new stuff to fool with, but
I'd really like to get the original factory presets.  After a little
searching, it turns out that patch 80 thru 89 are different between
the quadraverb and the quad+.  Is there any one out there who could
send me a copy of the parameters for the original factory presets

It could be as simple as sending me a file of sysex, which I could
then dump back onto my quadraverb.  I'm using a macintosh, but if the
sysex is sent to me as a text file, I could still use it (binary, also
can be handled).

Any help would be GREATLY appreciated!!

I use the QV along with an ADA MP-1 MIDI preamp and a stereo power
amp, controlled by the ART Ultrafoot controller pedal.  Folks, the
Ultrafoot and the QV together are an unbeatable combo.  The QV allows
for so much more realtime parameter mods than almost any other box...I
now have far less patches written than before because now I can vary
delay time, reverb mix, etc. on the fly!  I rely on the ADA for chorus
and the QV for verb echo and EQ.  I used to have a Midiverb II (which
I loved)...I think the QV is superior to all the ART stuff for the
guitar.  Alesis didn't load the DSP chip with all that harmonizer
stuff, in order to keep the chorusing and reverbs clean.  That's how I
like it.

Subject: Realtime

I'm using a pair of Roland pedals and an Anatek Pocket Pedal!to send
continuous controller data to my QuadGT during performaoces. I assign
the pedal to DelayMixVolume allowing me to use the Quad for constant
reverb on vocals, and fly in Delay as needed!with the pedal.

 I've also found that a very specific repeatiog echo can be created by
setting up a delay with a feedback of about 70%. Set it up at full
volume, and then set the PreampOutput to 0(zero). Assign the pedal (or
other CC device) to Mod the PreampOutput +99. When you send uhe
expected CC data, you will be "turning on the input" to the
delay. This causes only a single word or phrase to be sent to the
Delay. This word or phrase will repeat beautifully without being
covered up or smeared by words before or after it.  I can't remember
if there is a way to do this on a straight Quad rather than a QuadGT
(sold my Quad the day the first QuadGT shipped)

Is there anyone else out there exqloiting this particular ability of
the Quad, and what type of psoblems have you encountered?

I just have a plain old vanilla QV+, and it is basically a pretty

is OK live, but when recording it is unbearable. I have not looked
inside the unit at potential hot-rodding of op-amps to low noise
ones. I think that might help a little bit, but I can't see it making
a really big difference (otherwise someone would have done it by now).

I don't really have much other help to offer other than set the input

Do the same for the internal input gains, keeping the ratio between

Funny you should say this, I just went to the NAMM show and Alesis was
showing a QV2, which was fully stereo, and had 8 effects with fully
configurable algorithms. It also featured Digital I/O which were
compatible with those in the ADAT.

The MIdi controller does very well changing multitap delay lengths,
reverb decay on the wide open reverb sounds, ring modulator settings

the higher frequencies.  Maybe some chorusing, etc.

I like the QV reverb...I have a QV+ and a QV-GT...I've used them together
on a lead-vocal track to get a very smooth, medium room
sound: (I don't have the exact settings here...)
  QV+ patch is "medium room"
  QV-GT patch is a stereo-delay (~30 ms) with some chorus

If you just have one QV ;-)...
   try short stereo-delays with some chorus and EQ on lead vocals

> I am thinking about getting two ADATs also.  I tried to get a demo at

I was at NAMM and saw their pitch for the "Alesis Dream Studio".  I
must admit I am biased towards Alesis because they pack a lot of
features in for the money...on paper the new X2 mixer looks better
than any under $5000 mixer out there (including the new Mackie 8-bus
mixers). There is a lot of support for the A-DAT format from 3rd
parties--I heard DigiDesign will have an interface soon to their
Pro-Tools (and maybe Studio-8).

A couple of A-DATs, a ProTools HD recording system, a couple QV-2s
(much improved processing with digital ins and outs) and the X2
console--could be a dream home studio...

The setups for which I can see are not overly elaborate and settings
are not changed often (maybe once or twice in a year) since both

time, day after day.

My current guitar rig consists of an ADA MP-1 pre, a Quadraverb.  I
currently run them into either a reissue Marshall 100 watt Super Lead/
'69 tweed 4x12, or in stereo with a pair of 50 watt heads ('69,'76 -
unmodified) into a pair of Mesa Boogie 2x12's.

I'm sure there are others on this list that has the ADA/Quad Marshall
setup.  I got my MP-1 almost the moment they came out; same with the
Quad.  Seemed like the most intelligent cost effective thing to get.
Now, years later, everybody in town (Augusta Ga.) has the same rig!

I've been wondering about the input meter on my Quadraverb, though.  I
noticed in the FAQ a brief mention about some problem with them - mine
freaks out occasionally.  Does anyone know if this is just a prob with
older units?  Mine seems to function fine, except that the meter will
sporatically peak out at random.  I have to set the input knob very
low to avoid this.  Does the meter possibly reflect the entire
internal gain structure?  I know it reflects extreme eq gain

Also, I assume unity gain is about 1 o'clock on the input (sounds like
it).  Any thoughts about the output knob?  I know that the Quad, being
digital, has no real output voltage wise.  But I also know I can
almost overdrive the frontend of a Marshall with the knob cranked; so
perhaps somewhere in the travel it meets line level? I speaking in
terms independent of the internal "balance".

I would like to hear from others with a similiar setup (I know with as
many MP-1's out there someone should start a MP-1 list), share
settings etc.....

Wisconsin - Platteville, USA; Copyright _The Bottom Line_, 1994', end
of quote.  TBL is nice and has about 800 subscribers. All sorts of
things are discussed: influences, gear, playing styles, you name it.
I've read the archives yesterday and found out that I'm by no means an 
'advanced' QV user. Apart from a drumcomputer, I don't use computers and 
synths and stuff for my music, so it was fun reading that someone did still 
all his QV editing *by using the front panel knobs*. Don't know anymore who 
was this, but you're not the only one ! 
I'm not 'using' the SYSEX format so most patches are not for me, the only 
one that's usable/understandable for me was the 'big snare' patch, because 
it was 'in words'. 
Are there still other 'low-level' QV users ? I myself am not generating new 
patches on a weekly basis (to say the least), but perhaps we could exchange 
'patches in words' when we have interesting new ones.

Apart from just the bare data, I think it's interesting to know about 
the thoughts behind a new program. For instance, when I use this parameter,
it has that specific effect on the sound. With such comment, I feel I could 
learn a lot more of this than just entering the new program data.

Some more introduction: I bought a second hand QV by mail, but at home it 
turned out to have the new eprom, so I own a QV+. 
I'm a bass player (hello Rob Rathgeber, you're not the only bassist using a 
QV), and have used the QV+ with my bass rig for a while, together with an 
ADA MC-1 Midi Footcontroller. 

During last year, I've become more & more interested in home recording so 
I'm using the QV at home, it's more of use there. 
A few years back, when using the QV for bass, I used the space programs 
(mix of reverb, chorus & delay) for the quiet parts of the songs of the band 
I play in, and still use it when we play 'old songs', but our newer stuff 
doesn't need any form of FX on bass during live & rehearsals, so another 
reason to remove the QV from my bass rack and use it at home. I still use a 
BBE maximizer for bass, however, I'd wish I had a few more of these at home...

Nothing special, at home I use the QV+ with the AUX send of a Mackie 1202 
mixer (no dry signal coming out of the QV+). 
No problems anymore, but when I used the Alesis for bass (dry & wet coming 
from it), there were several things I wasn't too pleased with, as for 
instance the ridiculous functioning bypass when used dry+wet. (I added a 
hardware bypass, 'cos I didn't like the idea of a bypass in the form of 
setting the FX output level to zero: unnecessary A/D and D/A on the dry 
signal and level hassle...) In this situation, on times I had noise problems 
too, and this became even more prominent because of the hi freq horns in 
my bass cabs. 

Perhaps it's time now for my first question: who could tell me more about
the stereo spread programs ? Are they intended to stereoize mono signals ?
Enough for now,

smoother reverb by running the reverb output from the first to the
reverb input of the second.  IT DOES NOT WORK.  Apparently the delays
in the Quadraverb reverbs are fairly static (not random), so what you
get is very short delays conflicting with each other.  In real world
this means that the combined reverb sounds very metallic, instead of
smoother reverbs I tried to get in the first place.

I tried this with numerous reverb types and the results were always
the same. My advice is, if you want to use two QVs simultaniously for
better reverb, put them in parallel.

Of course, the Quadraverb is not a good choice for reverb in the first
place, either.  If anyone is willing to trade a Lexicon 300 or 480L to
my QVs, just let me know... ;-)

Regarding the Quadraverb II: this is a totally new effects box, which
has nothing to do with the previous model.  This pretty much means
that there will be no upgrade deal of any kind, since the units only
share a name.

It seems to me that any two reverbs (by any manufacturer) will act the
same way.  You are essentially pushing the signal through the second
reverb at the same time as the first, except the signal to the second
QV is reverb'ed.  The tiny delay through the electronics is what gets
you the "constant flange" (metallic) effect.

Instead, why don't you set up the second QV+ in configuration 1 or 2,
so the delay is in front of the reverb, and play with the delay time
on the second QV?  That may give you what you want.

For added effect, ping-pong the second reverb. :-)

I agree.  Another advantage of this is you're not amplifying and
reverbing the noise that the first QV introduces.  Guitar players
seems to like grunge, so maybe that's why they dig hooking up
long chains of boxes. :-)

Subject: X-15 and things

	In regard to John Soouthwood's post about getting an X-15....

	YES!!!  DO IT RIGHT NOW!!!!!  

	They're great.  I just bought one two weeks ago from Atlanta Rhythm
City (who tried to rip me off - gave me an opened box; told me they opened
it to make sure there was a manual in there; there wasn't, and then tried
to tell me "oh, yeah, those don't come with manuals - in fact, all of ART's
stuff doesn't come with manuals"- bastards.  Made me drive 20 miles to there
other store to get one sealed on a box) for $200.

	I bought my MP-1 right when it came out; I don't have the sys-ex
software, so I'm not sure how well that works, but the things you can do with
the mod parameters on the Quadraverb is tremendous.  I've been setting up
a few friends rigs in town (who have what I have - MP-1, old Marshall, Quad,
4x12) and most people set their left pedal for delay time, and the right
for the delay mix.  Which is pretty boring considering what you can do with

	The neat thing about the X-15 is the programmable bypass switch that
will control a neg. to ground switch on a device; but few people realize
it's also continuous cont. 84.  I've got mine set for a volume boost on
the Quadraverb, so if I get a wild hair when I'm on one of my rhythm patches,
I can hit it once for a boost and again to turn it off, without moving my
foot - which is great!

	What kind of map are you running?  To me exchanging patches on
disimiliar rigs is kinda strange, but....

Subject: QV+ tremolo

Looking for a tremolo for guitar (vibrato/tremolo, whatever, I mean
the fx that is found on a lot of old tube amps: amplitude modulation),
I realized the QV+ has one.

I tried it and apart from the desired effect, I heard (soft)
knacks. Is this common ? The effect itself is usable, but I don't
understand this strange side-effect. Any comment on this anyone ?

I'm owner of two QVs ( + & GT ) that I use with other
equipment in my home studio. I mostly do demos of
my own music but I recently recorded a demo for a 
afro-music band, too.

I'm actually a bassplayer so the QV GT is often
located in my EBS-system rack ( for those who don't 
know EBS: it is a swedish company concentrated to 
*very* high quality equipments for the bass ). 
The best for bass is of course the 'amazing bass'
patch ;).

I use mostly QV's factory patches with the mix levels 
changed to suit the use in the aux loops of the mixer. 
One of the reasons for not doing much patches myself 
is that I hate to do that tok-tok-tok-tak-tak-tak 
when I want to try some changes to the effect. This 
same problem is of course with most of the modern synths 
and effects. I'm using X-or patch editor in the PC, 
but its interface is not that good and it doesn't 
support + & GT models well. So if anyone has info of 
a qood patch editor/librarian running in the MS-DOS 
Windows environment let me know.

In the archives I saw many messages about noise problems. 
I also had those with allmost all of my equipment. The 
solution was to get the correct level of the signal at 
all stages to maximise the S/N ratio. There was a article 
in the Electronic Musician a year or two ago about setting 
levels in studio that helped me a lot. Actually the biggest 
noise maker with my QV initially was the transformer. It 
took me some time to realize where that huge hum was coming 
from. Nowadays I'll take all my transformers as far from 
the audio cables as the power cords allow.

Subject: QuadraNoise+ tremolo

Regarding the QV+ tremolo:

The clicking sound in the tremolo can be heard with extreme parameter
settings (read: anything over 50 ;-).  Some types of source material
will almost certainly introduce the clicking, regardless of the
tremolo patch you are using.

The problem with Quadraverb is that it does so many different things,
and does none of them very well.  At extreme settings of any
parameter, you will most probably hear artifacts.

Things that bother me most are the noise floor, noisy EQ, distortion
in pitch detune, metallic reverbs, and the fact that you can't set the
delay feedback to infinite (100).

I usually use my QV+'es for delay effects, with a moderate reverb setting.
I've actually found the one-shot sampler part in QV+ to be useful, and
I have used it in a few demos, just because the artifacts alter the
original source material beyond distinction...

As for the "Quest for killing the metallic reverb":

Bob Page >...set up the second QV+ in configuration 1 or 2...

Thank you, Bob. One of these days I'm going to try this out.  In fact,
as soon as I get the patchcord spagetti sorted out from my rack :-).

        Hi everyone! Well I just got my Qverb+ a couple of months ago. So
far I've used it on guitars, vocals, samples and tapes 'n' stuff. I have the
Qverb, a MidiverbII, a Peavey DD1000 dual digital delay, a Digitech Echo+,
an Ensoniq Mirage, a Roland S-220, a Korg DS-8, a mixer, a cassette 4track,
Vision sequencing software, a buncha MIDI shareware, and various tape decks
and turntables. 
        I can't really catagorize what I do 'cause it's pretty varied. I do
some sequenced music, freeform improv jams with friends, psychotic sound
mixes, spoken word, and I sing harmonies and engineer for a band with a
couple friends called the Poison Oakies (well, we've only recorded one song
but we're planning a 4-song EP).
        I'm into DIY sound of all sorts and DIY and guerilla media (zines,
pirate radio, etc).
        I'd really like a mac editor for the Qverb, or at least just a
librarian. I'd also appreciate any hints on books on using effects,
especially to build a sonic environment and sound plot (ala radio drama).
I'd like to trade patches with people but I've only programmed a few myself
so far, and they tend to be a little weird. Is there a SysEx utility
everyone here uses to trade patches? Or does it matter? 
        I'd also like to know how people use the ring modulator and

        Hope to hear from y'all!

You've asked for my setup, so here it is.
Yamaha DS55,
Akai S01,
Roland SoundCanvas,
Alesis D4,
Quadraverb Plus
 all linked to an Atari running Cubase.

I use the Qv mainly to clean up my samples,but also you the Qv when mixing.

Since I'm new to the Internet ,I don't know how to send my patches yet,
but I'll soon find out.

I have made a handy Desk Accesory for the Atari, which makes it
possible to edit the Edit Name of the QuadraVerb, simply by typing the
name by the Atari-Keyboard.  Is there someone out there who is
interested?  If there is, let me know and I'll send you the program.

Final Question :I use Version 2.03 on the Qv.  Is this the latest?
(Find out by pressing both Page-Buttons simultaniously in case you
didn't knew)

Bye for now...

Hi everybody,

as I'm new on this list, I'll introduced myself and my
setup. I'm a french tenor sax player and I use a MIDI
setup to compose my own music. My setup is the following:

- Roland U20
- QV+
- Casio RZ1 drum machine
- proteus/1
- PC+sequencer+SBPro card
- MIDI patchbay
- electric guitar
- TASCAM 464 4-tracks
- Sony DAT

I use my QV as an auxilary device on the mixer, not directly.
I use it for any instruments, even on the voice. I use very
specific programs and I'm not sure we can really exchange
patches. Anyway here are some patches I found on the net.
Be careful to save your full QV before loading them!!!!
I also found on the net a cheapware to deal with QV dumps
on a PC using a MPU card. Here it is.

Am I correct in assuming the enclosures which are not readable as text
are sysex dumps for the Quad?  I have been a long time Quad Plus user
(just didn't know of the existence of this list till now), and I just
recently traded it for a GT.  I mostly use it for processing
synthesizer/sampler sounds, dedicating an effects send/return path for
it in my mixer. With the extra capabilities of the GT, I'll
occasionally run my electric guitar through it also.  The guitar used
to be permanently run through a Rockman module, but the Quad GT is
quieter and cleaner, useful in certain situations.

I also had two Pluses purchased for work (Motorola) as accurate
programmable audio delay lines for experiments simulating voice delay
in digital cellular systems.  The cascaded EQ section was used to
simulate the telephone audio bandwidth with great success.

Enough for a first introduction - talk to you all later.

	I've been using a Quad GT, mostly with an electric twelve
string, a Les Paul & a shitty synth (which it does bring alive a bit).
I tend to have trouble when using the qv's preamp and my combo's
preamp in serial.  When you put the combo's preamp into the effects
loop of the qv a loud squeel is audible, though it can be reduced by
setting everything to clean sounds.
	Does anybody posses a qv patch editor for an ATARI st?  I've
seen a PC version but nothing else.

Subject: Mac Software for QVerb?

I have a Macintosh IIsi, a Kurzweil K1200, and a Quadraverb connected through
MIDI.  Is there any Macintosh software to allow programming the Quadraverb,
like a patch editor with graphic sliders?  Thanks.
