Aftertouch Weirdness

Post by Stuckinabox » Thu Jun 07, 2007 11:00 pm

While I was playing today I noticed that putting that extra aftertouch pressure on the keys was increasing the pitch about a half-step. I changed patches and it was still there. It didn't do it when I turned osc 3 keyboard control off of course, but while I was experimenting I noticed that even if I played a low note (with low priority) and applied pressure to a higher note, the pressure went through (kind of going off on a tangent here, but that makes you wonder whether or not the keyboard can send individual velocities as well as several keys at a time through midi).

Well whatever. It went away when I turned it off and turned it back on which I thought was a bit odd for a Moog.

Perhaps a software issue? What version are you running?

I think you mixed up velocity with aftertouch here.
Anyway, the aftertouch is monophonic as an 99% of all aftertouch sensetive keyboard actions. This is a problem of cost and a very special exclusive licence Fater (I think the world greatest keyboard action manufactur and supplier for Moog Music, Waldorf, Access, and many others non japan synths) was giving to Ensoniq.
And because of this, the pressure of the after touch is monophonic. And it would not make so much sense to have it polyphinic on a monophonic synth's keyboard.

About your pitch change when pressing the keyboard:
- What OS version are you using?

- Did someone ever opened the left hand section with the wheels? Maybe the ribbon cable of the keyboard is somehow bended or pressed by the left hand controllers when you move the keys all the way down.

- Have you a way to see check what midi data is send out when this happens?

- And does it still stay like this when you unplug ALL midi cables in the Voyager sockets? Maybe there is some controller mapping going on in a connected computer or keyboard.

Sorry, I said velocity the second time around. It happened with varying pressure, which is aftertouch?

I'm using 3.3, no midi cables, and like I said, I don't think it's physical cause I turned it off and turned it back on and it was gone.

There are sources aplenty on this instrument to keep you guessing, I agree. An aftertouch needing an upgrade on some of the synthesizers may add to some confusion. I am in no way qualified, but as a shaping device, I don't think it's given the same strength as a regular mod function. Maybe the velocity has such a curve that it lasts after the note. Nice place for another ADSR. maybe not.

I had the same thought process as you did, after the upgrade. Anyway, as is true for me, more practice is always helpful, in either case. I'd be interested in hearing more about the shaping stage from someone who often has use for these effects.

I'm an old analog guy, but I'm new to the Voyager. I programmed an awesome bass sound the other night that has pressure shaping to add a waveform change. It's a very clicky-attack, deep and clear bass sound, but when you push the key you get a low tuba-like growl that absolutely knocks your socks off! However, it still seems pretty much an off/on effect. It works perfectly in this case though as an accent to the round bass sound.

There are uses for an on/off for some of the modulations. I have to go back on previously not experiencing strength to the modulation shapes as the added response adds much to the tone. I suppose I'd do better to dig into the pot mapping as the modulations there hold much surprise in themselves. Also there is something I was told of about the shapers that acts well with glide.

I checked my bass patch and found that indeed there is a wide range of pressure/aftertouch sensitivity. Using the bass patch I mentioned, the Voyager is respoding through a wide range of waveforms according to pressure. So there's no doubt whatsoever that the Voyager pressure/aftertouch response in NOT merely on/off!

I'm using a Novation X-Station as a midi controller, and it is a high quality keyboard (unfortunately the pitch bender gives me stepping artifacts when I bend more than a whole step).

The aftertouch response was on/off like when using the Voyagers own keyboard. But now it is way better due to the hardware fix.

Oh yeah I forgot there was an after touch upgrade. I have a rack mount edition and I absolutely LOVE the after touch!

The biggest thing I DON'T like about the RME is the lack of jacks. When I got it home I was flabbergasted that it didn't have a pedal jack!

There is a spectrum of change, and adds to the patch performance. Perhaps the action is different from each keyboard, or the rate of pressure sensitivity can be set separate from the amount. Are you sure you didn't raise or lower the amount, instead of relying on AT?

Gonga, regardless of your midi board, I wouldn't think the AT would be affected. I wish it was as easy, but you have settings pretty much to your liking, if it was midi. But there wouldn't be a hardware fix if that was the case, and if the aftertouch given mattered to the patch you enjoy.

I had the sound cutoff from using ext/in, and only repaired itself turning voyager off and on. Unfortunately, my SE had a couple too many trips across country and I'm experiencing trouble with a few of the jacks.
