Scott. Yes I have the new BIAB2004 upgrade from v12c. I find it has a number of additions.
Import a midi file showing chords with just one button press F7.
You can morph all the built in styles taking any part Drums Bass Piano etc, mix and match from any style.
The main advantage of the program now being 32bit apart from improved graphics is its much quicker at building a solo or melody and faster at displaying notation.
You can now record vocal directly into your chord sequence and add vocal harmony using the TC-Helicon Audio Harmony.
Plus other additions including. 101 Riffs blues Piano. 101 Riff Jazz.
