Matt, a second MIDI bank opening would be a nice addition.

When I say I would like to have BiaB open all 16 tracks I don't mean it to be mandatory. BiaB could come with an A/B switch. BiaB would naturally come as A, in other words as it is now. One could choose to change it to B where all 16 tracks a open.

When BiaB started GM was the rage. GM was very simple to use. BiaB based itself on keep it simple with GM (which is still needed IMHO) and the harmony and guitar settings.

But, again IMHO, those days are over. We have users that only use GM and that is fine. However a number of users are using SFZ, Kontakt, ST3, etc for their sounds. They have learned how to assign BiaB tracks to MIDI channels. They could learn to assign harmony tracks. The same goes for guitar MIDI controllers. YMMV

I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!

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