Alesis Quadraverb Plus

I'm thinking of buying an Alesis Quadraverb Plus. It's quite cheap and I've read that it has find use from Aphex Twin to FSOL to Autechre. Especially Booth and Brown are really picky when it comes to reverbs.

Can you guys share some info on it? Any ideas if you can go crazy with it via MIDI?
skipperdean
i bought an original quadraverb last week, literally just racked it, haven't midi'd it yet... so far it does the trick and for the price it can't be beat.
RealDudes
doesn't it have some crazy effects like comb filter and other stuff? I'd imagine that a CV>midi module would be awesome with that sorta thing

Ive got a quadraverb gt and a midiverb III, both sound really good. Programming can be a chore for some people but I dig it.
Paranormal Patroler
Well I don't mind programming to be honest, although I've heard it's quite easy to do with the QV. How far can you go with it MIDIwise?

I really want a reverb that I can mess up in real time. You know, panning tricks, reverbs coming and and going out in crazy times, stuff like that. I've read the plus has a multitap delay which I think might really come in handy.

I've got one of those. There are a lot of options for midi cc control of parameters. I think it has 8 CC destinations per patch. I don't think the Delays or LFO's sync to midi clock though.

They have pressure sensitive buttons so pushing harder makes the parameters scroll faster. That makes programming a little easier. There are a lot of parameters for setting levels of the routing. The routing and mixing of the effects is quite flexible which makes it fiddly to program.

There is a neat resonator program that takes midi note on/off messages and controls band pass filters. You can use it to turn pads in the rhythms.

There is a strange Ring Mod program that lets you separately control the level of the Sum and the Difference components. Unfortunately the inbuilt modulator oscillator has a limited range.

The main attraction is long washy reverbs. Great for ambient stuff and shoe gazing guitar. I think most people just leave them set on the Taj Mahal preset.
Paranormal Patroler
Wow, if the Delays don't sync to MIDI that would really suck. But then what would the Tap Delay be in that case?

I can't seem to find many info on the MIDI implementation but I think I'll get the QV+ just because it's cheap.

Is it that noisy?
skipperdean
Not that noisy.

Multi-tap delay.
Paranormal Patroler
I think the Resonator stuff alone is worth , don't you agree? I just need it to be MIDI controllable so I can do this:

With the regular quadraverb you can use 8 MIDI controls at once. If you apply fast enough modulation to any of the parameters it will sounds "crazy". I mean, just set the stereo delay to high feedback with short delay times and and assign a MIDI S+H LFO to the delay times.

A MIDI S&H LFO? Didn't quite get that. hmmm.....
jonah
Well, what are you planning on controlling the quadraverb with?
Paranormal Patroler
Shit, this can get really complicated to explain. I was thinking of creating something similar to the video I posted above of that Buchla module and I tend to use a TenoriOn as a MIDI controller for everything.

Are you at all familiar with its functions? It has this cool Bounce mode where the notes move vertically on this 16X16 grid, so I was thinking of using each vertical line as a separate EQ band. But then again the QV has a 5 band EQ.

Anyways, the TenoriOn does output NoteOn messages and the Quadraverb does this perfect thing of accepting NoteOn messages as MIDI modulation signals for the parameters so I think I'll try that one up.

Apart from that I can remap NoteOn messages to any possible MIDI message so that wouldn't be a problem. What do you have in mind?
jonah
I have TNR-i and yeah, bounce mode rocks! Can you remap each of the 16 note ons to any MIDI CC?

Actually, you can set positive or negative mod amounts on the quadraverb so you should be able to get interesting results even only using note on values.

I thought you wanted the sound to change like in that video, but you're more interested in "drawing" the tone with the TenoriOn's bounce mode?
Paranormal Patroler
I do like the sound of that video, so if you have any ideas on how the QV could achieve that sound please post them. I'm sure people around would like to know as well. Do tell about the MIDI S&H LFO.


As for the TNR,

To be honest the basic idea that came from that Buchla video was the vertical movement of the EQ bands. I instantly thought "that would be a cool feature on a TNR. So how do I go about programing something like that on Bounce Mode?".

So I run into the QV which looks promising on many different aspects. I'd like to be able to control things on the QV via the TNR and I have a MidiSolutions Event Processor that can handle the MIDI remapping. But after looking into it I have to say that it wouldn't work the way I want it on Bounce Mode, although I could achieve something similar on Draw Mode. Don't know how it would sound but it looks promising as I said earlier.

Anyway I wouldn't like to derail the thread even though if I started it myself. If you are interested, since you do own a TNRi, I'd be happy to discuss the TNR programming part privately.

the plus model has resonators that i heard are really cool , the 1st version doesnt.

Both versions have more soul than virtually any other verb on the planet .Its a certain vibe and sound that some slag off but if you like that early vibey idm then the quadraverb is essential.

Put an sh 101 through a quadraverb on a long setting and your there.
Paranormal Patroler
Shit, you just about have persuaded me. It's dirty cheap so I might as well go for it.
deastman
The difference between the Plus and the original is just the eprom, so you can upgrade it if you can locate a copy to burn. I do love the reverb, and the resonators are pretty cool. I have to disagree,however.... It's horribly noisy.
Paranormal Patroler
Oh the one I have in sight is the plus alright, so no upgradin' needed. Nosy in a bad/unusable way? It's like my producin' is state o' the art for that matter.
deastman
Nah, its all good. Just don't be surprised if you hear some hiss.
hangovercat
Just for the sake of comparison, consider the Lexicon LXP 1 and/or 5 if you see them for sale. They were also very versatile in terms of MIDI specs. Never owned either myself but people always spoke highly of them.
Paranormal Patroler
I think I can handle the loss of 80 euro for a little bit of 1U crazyness. SlayerBadger!

i have a quadraverb here thats not so bad , the big issue i find with them is the input overloads one minute and the next minute you dont have enough signal coming in.
wsy
I've had a Quadraverb for 20 years. Back then it was considered a "rack mount supercomputer", and had to get a special dispensation from the US Department of State to allow export.

And yes, even the first version can do a great moving-tap comb filter controlled from MIDI.

I have no intent to sell mine. They're good machines.

Is it the guitar version? Those tend to overdrive the input signal 'cause they have more gain for the guitars.

Oh, wow I didn't know that. Is there a good, cheap, reliable place to get the upgrade in the US?

I came across this link regarding the noise while looking for an eprom. My quadraverb doesn't seem noisy either . http://charliehall.proboards.com/index.cgi?board=project&action=displa y&thread=4712

Waaaay back in the day, there was a music-related BBS in San Francisco, whose name I forget. The sysop had a collection of ROM images available for download. I had to go to his place for something or other, and let him make a copy of my upgraded Plus ROM. So I know that at least one copy must exist out there in the world. I'd be surprised if you could find anyone selling them at this point, but they are easy to duplicate if you have one to copy.

I have an original QV, not the plus.
I love it for synth work, mine's pretty much stuck on a slightly tweaked version of the "Deep Space Eko" patch (long, deep, dark verb) or the resonator (awesome dubby vibes like the resonator plugin in Ableton).

Haven't fiddled with MIDI control much, so nothing to add there.

Haha, wow.. BBSs! That brings back memories. I think I was 11 when I last used one. Downloaded Doom and ZZT, got virus! ..Modem configuration. cry

I did find a few places selling the eprom... The only one that doesn't seem horribly overpriced or sketchy is on ebay.co.uk and I can't contact them! I asked Alesis if they'd sell me a copy or give me a download link. I'm not hopeful though.
Paranormal Patroler
Quadraverb+ on the way and I've downloaded MIDIQuest XL so I can use the editor to save me the fuss of making patches without a GUI. Let's hope it will turn out as good as I imagine it will! w00t
deastman
Let us know how it turns out. I'm curious how it will sound to an unbiased set of ears...

I don't actually think MIDIQuest is necessary for this one. I hate one-line displays, but someone always found the QV easy to program. The pressure-sensitive buttons help too.
thetwlo
wow! bought one new(about $379?), the + upgrade was like $30.

i kinda hated it but, i'm sure you can get good things out of it.
The later Ensoniq stuff was just sooooo much better, for "budget" fx.
jonah
Thanks to Reality Checkpoint's generosity I was able to get the plus EPROM at a decent price and I'm really digging the new features.

I'm bummed you can't MIDI control the start and end points of the sampler via MIDI (I was hopping it was just undocumented), but it's still cool. I'm gonna keep an eye out for another one, I think.

By the way, I love the way Alesis made the case, seriously friendly and simple to get into.
Paranormal Patroler
Got it but still haven't plugged it in. very frustrating
Klaus
Resurrection !!

So, delay tempo sync?
stk
I've got an original, love it. As mentioned, dark washy reverbs that don't even try to be realistic.

The resonator is awesome. IIRC you can't control the reso delay line times via MIDI? I might be wrong, must check.

There's some other nice stuff - stereo detune, leslie emu..

RE: tempo sync, I don't think so, I'll try to check tonight. Meanwhile, the manual: http://www.alesis.com/stuff/contentmgr/files/0/19510d5a385b3780e57d6ed a1f86b1ad/file/quadraverb_reference_manual___v1.0.pdf

one of the coolest things you can do is use the resonator and control the pitch of the six resonators by midi.

Whoa-- that's cool! It seems like the Quadraverb can do some of the things the Moog Midi MuRF does.

I've had my Quadraverb+ since the dawn of time. Sound quality is ok but nowhere near as good as a Lexicon. The MIDI CC's aren't as useful as you would imagine, there's a lot of "zipper noise" as you change parameters. Which is a pity as I'd love MIDI control over the ring mod. Unfortunately you hear very audible stepping as the CC values change.

Also, the unit doesn't respond to MIDI clock so you can't sync delay times to bpm. This is how I learnt that 60,000 divided by bpm gives you milliseconds per quarter note!

I always kept a little scrap of paper next to mine with chart BPMs on the Left and columns with 1/4 note lengths, 1/8th note triplets etc.... laminated with cellotape!

I am only posting these remarks so that i can open my first thread... My Quadraverb is drawing too much current. I need some techy advice ! help

This was my first rack-mounted effects unit I purchased back when I worked at a music store giving bass lessons. I still have it and use it.
Gisel
Can someone explain which CC is for which sound parameter? I want to control the QV with my Pyramid but I just can't figure out how..
