I always try to find a way to play a bit with left hand only, to facilitate grabbing a drink.We take levels b4 we start(PA is voices only). After the first song[we usually open with 2-3 instrumentals], I make adjustments, usually volume only, occasionally EQ. If necessary during a song, I'll play a few measures left hand only hammering and tweak a knob insert 'ahem' here with my right-a technique I developed early on so I could keep the bass line going and have a drink with the other hand, easy to do playing bossa novas.
My cover band has vocals, keys, guitar and horns going through the PA.
I also run the lights with a foot controller.
Nice thing about the digital mixer, is you can save and recall settings for the room.
