I'll be so happy if someone can help me with this problem - I've been using MIDI to connect my PR200 to a sound module. I can't understand why the music from the piano's 'play sequencer right' can be heard when MIDI'd, but the music from the 'play sequencer left' can't be heard at all. To me, this makes no sense! Please let me know if you have any ideas about this, thank you ever so much.
