Kind of crude indeed, as the displayed chords didn't really look like what's been played to my ears: IMO key of Dm with about only a C (modal key) as changes, and when there's some more interesting chord riffs, they're missed altogether by RB (?). However the added bass track seems to fit, playing G notes over an IMO C-chord of the guitar LoL. I also experimented with this audio analyzer (in BIAB) in the past, and found it useful and kind of working, but only with simple and clearly recorded material. But you got me curious, next time i'll try Realband. Thnx, F
