I recently picked up 3 Roland M-series rack mounts (MVS-1, M-OC1, and
M-SE1).

These use the same sound engine as the JV series expansion cards
(discontinued in 1999, to the best of my knowledge).

Hunting as we speak for a patch editor for these for Mac. As usual, PC
ones are easier to find. (no comments, please;-).....)

Please email me at lindaleed@earthlink.net

Thanks,

Linda
