Using Ableton Live I’ve got my Komplete Kontrol S49 MK1 sending usb midi to the Analog4 MK2 via Overbridge plugin. For some reason as soon as I hit the slightest aftertouch on the Komplete Kontrol, the pitch bend shifts down as low as possible. Sliding the pitch bend ribbon resets it to center. If I play with aftertouch pressure while sliding the pitch bender I can hear the two “fighting” back and forth as the conflicting messages are sent.
Watching messages from the Komplete Kontrol via MIDI-OX confirms that it’s indeed Aftertouch messages causing it, no errant Pitch Bend messages are being sent.
In the Analog4 Sound Settings Aftertouch is assigned to OSX vibrato as is default.
I tested the S49 to Analog4 via MIDI cable and the problem was gone. Unfortunately not a viable solution for me though as the S49 MIDI mode only works with USB unplugged.
I also tested playing my minilogue with the S49 through Ableton Live the same way; no aftertouch pitch bend weirdness.
I’m a little out of my depth here as to what might be causing this. Any ideas?
I suppose I could use the minilogue as controller instead (indeed it’s much easier to change the midi send channel) but the keys leave a lot to be desired next to the Komplete Kontrol. I considered filtering out aftertouch messages as well; I don’t use it all that often, but it seems more like a bandage than a true fix and I can’t think of a simple and flexible way to do it offhand.
