Hi Rachael,
don't know if BIAB has limitations,, but my PA800 keyboard uses midi styles, and the bass lines can sound brilliant.
Bit off topic, but currently I'm trying to find a way of mixing PA800 style tracks with BIAB style tracks in Real Band ie backing track recorded in keyboard, saved as midifile, then replace the odd track with a Real Track from BIAB.


best wishes
