I think the MVS-1 only uses 8 MIDI channels. If so I would daisy chain the JV-880 to the MVS-1. Assign MIDI channels 1-8 to the MVS-1 and channels 8-16 to the JV-880. If you need more than 8 channels for the 880 then this wouldn't work.

Ps - I have the 880 and it does have some decent sounds.


I haven't lost all of my marbles but there is a small hole in the bag someplace!
