hi,
for some reason logic x has stopped transmitting notes/clock etc to external synths. it still receives the midi in info and the mtp express 128 still shows up in audio/midi setup but the midi doesnt go out to the connected external instruments
any ideas why it would suddenly cease to work?
I'm on OS X 10.12.1 and logic 10.3.3 on a trashcan mac with mtp midi express 128
thanks
