Got the following issue; i want to use the synths in kontakt as multitracks and i am not able to get Kontakt to respond on anything but midi channel 1. I want to have say an oboe on midi channel 1 and a clarinett on midi channel 2. Midi channel 1 is working fine, but as soon as i try using channel 2 or higher, nogo. Guess there is something im missing in setting the whole thing up? Or are there any known bugs with sonar & kontakt?
