Doepfer ribbon controller with Nord Modular?

[Taylor]

Does anyone have any experience with this? I recently got a Micro for use as an audio processor, but am interested in using it as a synth. I'd prefer to use a ribbon controller over a keybord.

I'm sure it would work, but I'm interested in how well it works. In order to use the "Trautonium" mode of the R2M, the synth needs 5 octaves of pitch bend to get the full effect. Does the Micro have this? Thanks.

Hmmmmm, You could internally amplify the pitchbend signal to range over 5 octaves, that should work. What data exactly does this thing send out?

[Taylor]

Midi. (CV too, but that's of no use to me). So how would I amplify the pitch bend signal?

Here's what I'm talking about.

[Kassen]

Yes, I realised it's MIDI, what I wanted to know is *what* MIDI data, when en what you'd like to do with it. For example CC'S and pitchbend would be easy to deal with, NRPN's less so. That page you linked to tells us most of what we need to know.

Amping a pitchbend signal is easy; you take one of the keyboard modules and a amplifier, you patch the pitchbend signal into the amp, then patch the output of the amp to something like a osc. You can then set the amplifier to the disirered amount of amplification, you may need to stack up two amps if multiplying it by 4 isn't enough.

Next up would probably be some way of triggering a envelope. For this we'll take the note on message that the ribbon generates, just patch the "keyboard gate" to a envelope. As I read those specs you should leave the normal keyboard CV out of it all and disable the link to the keyboard that some oscilators have, instead only using the amplified pitchbend signal.

Once you get it all calibrated I think this should work quite well. Pitchbend in the NM is a controll signal like any other; you can scale it to behave like you want it to so 5 octaves would not present a problem.

Thanks for the response. Sorry for not being more specific, but MIDI is pretty alien to me. I never even considered amplifying a control signal...
