Do any of you experienced professionals on the forum have advice on how best to use BIAB as a backup when playing the melody on a keyboard. Just BIAB, I would rather not get into Realband. Also I don't sing. Some specific examples would be great.

Since many of the styles have an accoustic piano I often substitue another instrument like vibes or organ for the piano part while playing from the sheet music on my keyboard. Sometimes I don't play with my left hand because it seems to clash with the style. I also sometimes add a solo RT and mute it for the first time through. I have always played for my own amusement but now have the opportunity to play in public so I would like to sound a bit more professional.

Thanks
Tony
