I am posting here since the Jack-Rack Mailing list is looking decidedly
unmaintained.
I have discovered a small bug in jack-rack which I at the moment cannot seem
to find the source of.
Which is that feedback for midi devices is sent one channel greater than it
should be.
IE... If I have a controller set to Channel 1 CC 7
feedback comes back on Channel 2 CC 7
Channel 2 sends midi back to channel 3 and so on.
(the next slider on my controller)
