I've double-checked that my Volca Beats is responding to notes send and it's doing that fine. About the only issue is that the open hi-hat is set to the same note as the half-closed hi-hat on my RY-30, so patterns written for the more common hi-hat mappings are missing open hats if piped to the VBeats.
Reminded me that MIDI standards are not standards if everyone makes up their own. Is it so hard for everyone to just put open and closed hi-hats on the same notes. I know that a 'studio' kit will have half-closed, but for the love of Roger, how about make this big-arse drum map that includes all the fancy instruments and variation on them in it? Like instead of putting a bunch of the simple forms next to each other, put all the forms next to each other. Have all the various positions of hi-hat adjacent on the note numbers. Same with snare(a), snare(b) and rimshot. Really I should go join the MIDI org forums and put this rant up there, as they are currently trying to reinvigorate the MIDI world....
