Thanks for the reply. Yes I do have the current driver installed.

I am now noticing that as I play the Motif ES6 keybed I can see the keys being played on the BIAB 2014 piano window Thru keys, but no sound. And although I click and select a THRU patch change, it doesn't occur. It reads 'Instrument: No Patch Change' every time.

In addition mouse clicking any of the other track's piano keys does not produce a sound but clicking Play will play the song file.

The Motif plays LOGIC patches and functions well as a controller in LOGIC. I have tried several scenarios in the BIAB MIDI setup but think this should be it:

MACOS X CoreMIDI
MIDI In set to Port 1 (Motif ThruPort is also 1)
All out ports set to FireWire 410 (my audio interface)

I just want to be clear: I am trying to be able to select a track to play and/or record that track's assigned patch via my Motif keybed. Although I don't expect any control functions I'd welcome that capability.

Thanks again and thanks to anyone that has any input.
