Mario,
Thank you for chipping in. I am a Cakewalk dude.

I wonder... Some developers can amend things fast if they feel it's beneficial. Especially in early stages of release. Perhaps if it's not too tricky they can do something to V2.0 so it accepts a Chord Track from BIAB (and other software)

If v2 of Toontrack will not have that feature, perhaps people on this forum who prefer a smooth integration with BIAB should cook up a joint letter requesting this to happen?

P.S. I would be very interested in new Toontrack Keys if it would play friendly with BIAB. With partial regeneration + Chord Track, I spend much more time in BIAB than I used to, not having to jump between BIAB and DAW.
Having another flavor, would definitely enrich BIAB experience.
