I have a Zoom RhythmTrak RT-123 drum machine. It only has a MIDI in, and I want to have my sequencer (Cubase SL) trigger certain sounds on the Zoom. My problem is, the sounds I want are not in the GM drum map. I am having a very difficult time figuring this out. I have the Zoom manual which maps the sounds, but the numbers don't seem to match up with the options I have in Cubase. For example, in Cubase I have options like I-Note, O-Note, and channel. On the zoom, I have info like Note, Pad and Kit number. Can anyone give me the secret code to unlock this? This seems to be my biggest MIDI issue - mappings sounds.
