Hi all,
 
I'm able to record MIDI from my keyboard to a MIDI track that feeds Breaktweaker (the notes show up in the track after recording). However, Breaktweaker isn't receiving any of the MIDI. Fortunately, BT has a MIDI indicated in the UI so I can clearly see it's not getting the MIDI. 
 
Any ideas?

EDIT: Sovled. Turning Echo On for the MIDI track sends the data right on through to Breaktweaker. Problem solved! :)
