I'll start. Here's my live preset. (I also use a Faderfox LX-2, FCB-1010, and Yamaha DD-55 percussion controller.)

Top row: Rotary encoders push to stop Deck A main track, Deck A loops A1 & A2, Deck B main track, Deck B loops B1 & B2. Scr/Lnch knobs turns to scroll through scenes, push to launch scene.
Button A sets crossfader to 100% A Deck. 8, 16, 32, 64, and 128 are automated quantized crossfades (8 beat, 16 beat, etc). Same for B deck. A=B sets crossfader equal. RST resets all controls in Live and on BCR.
A, A1, A2, B, B1, B2 are sends. Rear row is to rear of room PA, middle row to front of room PA. P is front of room and rear of room live Impulse percussion sends. Viz is audio level that feeds a visualizer to Arkaos VJ (I do video and lighting in Live and play percussion while DJing), PM is percussion IEM volume.
VA and VB are deck volumes, FM and RM front and rear IEM percussion volumes. CV is click track volume, T tempo, and AxB crossfader.
Buttons on the right start and stop the click track, stop Live play, and reset Live.
