Hi Big John,

The reason you can only hear the MIDI tracks when listening with headphones that are plugged into the 1080 is that the 1080 is only getting the MIDI tracks and not the RT tracks.

I work in Sonar but this will work with any DAW. Move/copy all BiaB tracks to a DAW. If you don't have a favorite DAW use RealBand as it is very good. The MIDI tracks should go to the 1080. Now you must run audio cords from the 1080 line outs to your audio interface line ins. Now all of your MIDI tracks and RTs will play through your speakers and/or headphones that are plugged into the audio interface (which audio interface do you have). I have a JV880 as well as a few other hard synths and I use the above procedure all the time.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
