Update:

Client asked me to come in this morning and set up my rig so he/we could assess the volume. I set up my Tyros with the small yamaha speaker system...

It filled the main room...plus carried out to the bar. I was on about 70% full volume...I'd need to drop to about 40-45% as the place fills up...

Got three dates set up in August to try this out. After that, we both talk about how its going and then proceed accordingly. I really hope this works out because it fills such a nice hole in my client roster.

First night is Thursday, August 11th...I'll post afterwards my observations...
