My two thoughts.

1- My dad, a concerts pianist never played a keyboard well – partly because of the feel of the keys, and his state-of-mind. Keyboard players are a special breed, we like to think of whatever a lot.

2- The last time a played a county club they requested a trio. I added a bass player and a sax. I had to place the bass player next to my speaker because he was not use to playing with the exact tempo of our keyboards. I had the same problem when I used an electric drum and my guitar -- I felt it was taking away my control.

If you are going to lower the volume of the drums you may have a problem. The bass player is the heart of a band – when playing with a keyboard that changes.
