I'm a big believer in the KISS principle - Keep It Simple Stupid. I only use BIAB live. Here's how I'm set up -

BIAB on an old(er) Mac laptop.
USB to MIDI adaptor connected to Yamaha MM6 keyboard.
Realtime playing through a second keyboard.
Both keyboards run through a Peavy KB400 keyboard mixer/power amp - 400 watt power amp to a JBL4612 speaker.
PB400 output is also sent to the sound system

I have over 300 arrangements in the Mac. I can get to any song with 2 mouse clicks.
