I will try the expression pedal later today, but I would still have another problem. I was at a gig, and had to constantly readjust the mic volume to compensate for decrease in master volume.

This problem is really academic in that I plan on side skirting the issue. It is like trying to make a silk purse from a sow's ear. On the other hand this wonderful KB is so versitile, it probably can be accomplished.

Congrats on the new toy. Knowing your delving mind, you will have lots to share. I am glad you like it so far.
