I would like a MIDI only BIAB as before the Real Invasion with the option to not even download the Real tracks and Instruments but with the relevant program core improvements.
I have worked with MIDI since the late 1980's and find the Real stuff limiting for the way I write and produce my songs. Just my opinion as I anticipate many will strongly disagree, but maybe not comment.
I still haven't even scratched the surface of the multitude of MIDI styles and realise that PG Music are sadly now heading away from the way I work.
BIAB will always be a great program tho' and be the first I use once I have written a song.
