Thank you for reply.

I do not believe I was clear enough when I asked first question.
Got two tracks with identical chord progressions. They are played octave apart. If I have 2 waves + corresponding SGUs in one folder = single User trk, will it randomize chords from both waves (on regeneration) or BIAB will stick to one Wav file in a project?

Interesting concept with voice smile
Most of transposition works well in previous User Tracks I tried. Hiccups usually happen on Dim, Sus chords, which is somewhat expected.
