I am considering the BK-7 but there is one feature very important to me:

Can you change the indivudual instrumentation of a style?

For example: If a style has an acoustic piano in track or channel 3 and Strings in 4. Can I replace the Acoustic piano with an electric piano and the stings with a Pad?

Can I also change the type of Drum kit and type of bass. I know you can mute parts of the style but the manual is not clear on the ability of changing individual instruments.

Thanks,
Joe
