Subject:RE: MIDI drawbar unit on EBay

< need a mapper. The MIDI Drawbar Module (MDM) sends CC#12-20 as the "main"
drawbars, and -- if it's a newer version -- CC#21-29 as the "aux" drawbars.
These values don't perfectly map to most of the other clones.>>

Yes, but they do map perfectly to the B4 with no midi mapper...
