I have an ancient S&S Industries e-drum set with some Pintech Visulite cymbals driven by an Alesis D4. I'm actually out of inputs on the D4, plus I hate the silly 2-button hi-hat controller. Megadrum would seem to fit my needs of more inputs and variable HH controller support. Additionally it'd be a fun project as I like to build things, though usually mechanical. My electronics experience has been soldering a few microswitches to my paintball controller boards. I'd go for the 32 input super duper Mega Drum with all the options.
Anyway, a huge requirement for me is that all of my my musical gear be rackmount as I like things tidy and it helps hide the nasty mess of wires. Where do I come up with some compatible 1U-2U rack mount chassis for this project?
