After a night on duty at the hospital, I\'ve unsuccessfully tried today to solve the following problem. Loaded two instruments in GSt, activated Cubase VST and found that modulation midi control on channel one yielded consensual behaviour on channel two. This fact is apparently restricted to midi controller # 1, since all other controllers seem to act independently on different channels. I couldn\'t find any explaination to this apparently serious bug. Perhaps I\'m too tired, so I need help.
