I have several midi devices. One is a Roland M-VS1 module. I set the midi receive to channel 4. It still receives on other channels...WHY??? I use a Fatar 88 key midi controller. I can enable midi track 2 in cubase and it will trigger the sounds of this module...Everything is on Midi channel 2..I don't get it??? I only want it to receive on channel 4 and that's it!!!!!!!!!!
