Hi Andrew, thanks for getting back to me. Sorry for the convoluted explanation, it gets complicated using 4 hardware synths, a sound interface and a midi interface. What I am trying to do is to play the DX7 in realtime and not hear the ForteDXI play along with it. Whatever voice the Forte assigns to channel 5 is the voice that plays along with the DX7. Its the same pitch, its just another voice sounding with the DX7. I would prefer to hear only the DX7 when playing in realtime.

To resolve this, I moved the midi part of my system over to a MOTU 8 port midi interface. Now the DX is on port 2 channel 2 and the other synths are assigned to their own independent ports and channels.

Still what ever voice Forte assigns to channel 5 is played by the DX7. The only way that I have found around this is to mute the "Thru" channel in BIAB, then the DX7 sounds by itself.

Perhaps I am not undestanding what the "Thru" channel is supposed to do. Do you have to mute it when you play live with a hardware-based synth?

I appreciate your continued help and support.

Jeff
