Let's make it a trio.

I also use the TC Helicon product for voice harmonies on certain songs. I have to remember to uncheck the 'use VSTi/DXi Synth' setting in order to play the midi data BIAB produces for that particular song and then remember turn it enable the setting after the song is over.

Maybe the solution would - have each song save the check box 'use VSTi/DXi Synth' setting (checked or unchecked) on a per song basis. ???

Just my thoughts.
