Thanks Noel, i'll give it a try.

PS a Q: i loaded one of the Holds_120 files, SH1201, into cubase. It seems that there's no set tempo (bpm): somewhere swaggering around 116 it seems. Wonder if that hampers BIAB's analysis.

I just tried out Chord Pickout, demo version. Seems doing a lot, but does make mistakes on jazzy chords like suspended etc it seems, nut 'normal' chords seem to be OK.
