Hi all........I'm making another MIDI controller using a Teensy 2.0 & 2 x 16 channel multiplexes and I keep getting this Automatic mode disabled message.
I've used variations of this code before without problems. I've tried it on 3 different computers with same result. I loaded the Demo Reel 100 Fast LED code which works fine so I'm at a brick wall. Any ideas?
