I have BIAB 2016 intalled and it works like a charm, EXCEPT that i cannot get external MIDI to work properly. I have Komplete Kontrol S49 hooked up and configured in BIAB. It works, i can record MIDI on tracks and I can see MIDI in e.g. the MIDI monitor or the big piano window. BUT i don't hear anything when I play or record.If I record and then play back, sure enough the notes I played and recorded are there and I can hear them, but i hear nothing when I play live. Very strange to me. What am I missing?

The MIDI is going out to a Yamaha PSR-S750 and that works well during playback, but I never hear what I'm playing on the keyboard.
