Thank you all for responsiveness and patience. You guys are just great! I finally figured out that what I wanted to do with my H9 is beyond it’s limits. I’ve just ordered a Source Audio Soleman MIDI system controller, looks fine for my needs. I just wanted to control a Positive Grid Bias Head with it, and it works perfectly, but for just one project at a time. Never mind, keep on creating your magnificent machines, their sound is incomparable!
