Hi

Total BIAB newbie here -

I'm trying to generate a backing track for Yardbird Suite for my alto sax takenfrom the Charlie Parker Omnibook. The book is already in Eb.
When I enter the chords they are in the wrong key if I specify Eb in the chord selection box on BIAB.
If I import the track into BIAB it says the key detected is C.

Confused i am?

Help/enlightenment greatly appreciated
