Yesterday had an issue with C6: was trying to trasfer a pattern+kit from my computer (osx 10.8) to my Machinedrum with a DIGI002 as MIDI interface. Had no luck. So I switched to another MIDI interface, M-AUDIO FW410, and bingo! Strange enough since never had a problem with C6 and DIGI002 transferring to and from Monomachine. I find C6 to be buggy (still). Anyone had luck with some other sysex manager?
