Getting there, will write it all up later today (got the PX560 patch file, enabled Reaper for CASIO MIDI & program changes, triggered individual voices as desired, but with multiple Reaper tracks one voice will affect voices on other tracks) -
1. what port should the MIDI in port be ideally set to - A, B or C? Or does it not matter?
2. should I send each voice / part / stem / track to separate MIDI channels?
3. Should the Keyboard Channel parameter in the MIDI section (second screen of menu's) remain at 1 (default) or be changed to something else?
Thanks to all for your input & advice, greatly appreciated
