I just spent most of the day playing around with RB I almost think it would work for us,+ has some additional benefits. But I don't like the way it handles the midi thru channel. I need to use the computer soft synth for my 2nd keyboard sounds. 2 problems, first I can not program keyboard patch changes in to RB that occur with in the song like I can with BiaB. Also Keyboard sounds patch seems to depend on what ever track is selected in RB, it does load the correct patch but will not play it unless proper track is selected with a mouse click.
It make me nervous to think may start playing live and find the drum track selected and just a bunch of drum sounds from my second keyboard.
Maybe some more time and it will work it self out. I have not given up yet but discourage. I am leaning now to look for a old copy of 98 sp2 and load it and try the old Midi Mapper, some threads say you can split channels within.
thanks for the support hope for some more suggestions
