Accord for Max
I've ported my monome app accord to Max now. Should work just the same, though Windows users might find it more stable, and with better MIDI latency. It's amazing how porting something can open your eyes to a completely new way of looking at a problem. The chord/arpeggio handler is now much neater. Puredata version has been updated too.
