Hi Cajun,
you can take out some of the repatition
in just say a omb ( psr ) style if you want to reprogram it ie you could have slight variations when you play, major chords , min chords or 7ths etc just to make it sound a bit more interesting.
Not as varied as in BIAB though which basically chooses it's patterns randomly.

You'll have a lot more fun having your psr midied to your pc.

Now you've caught my attention. Are you saying you have an mp3 of George Shearings & you managed to mute some of the tracks & you've played those parts instead?? Sort of music minus 1 concept??

ie might I be able to for instance mute Enya's Watermark solo piano part & play it myself instead?? or has my imagination just run away with me haahaa.

best wishes
Rikki
