I use a Peavey PC-1600x device, has 16 sliders and 16 buttons. I have used it on Technics arrangers mostly, may soon adapt it to work on my S900 or (someday) a new Tyros 3 ...

It's a simple, yet flexible and programmable, box. I love having real-time control, smoothly, over various volumes, effects depth, filters, brightness, etc.
