Hi Peter and thanks for your response.

I am playing in a swing band on Tenor Sax. When I come to a solo invariably the staff is notated with chords. I can enter these into BIAB and these are what I will play and are correct fro the Tenor Sax but not the piano/rhythm section

I want BIAB to play the rhythm section so I can practice my solo, however I cant seem to be able to transpose the piano/base part etc to the correct key. When i do this it also transposes the Tenor part?

Hoping this gives you enough info

Malcolm
