Not directly related, but a singer from a death metal band I was playing in has once had an idea: a death metal drum machine.

In essence, it would be a box with a crank that would produce a blast beat whose tempo would be proportional to the speed of cranking. Something like a blast beat music box.

Can be made digitally by using a stepper motor wired as generator with a hand crank, then picking up the spikes which are proportional to the rotation speed and feed them to a ucontroller with some sound samples in memory arranged ad a rhythm, then play them according with the detected speed.

A simpler one could use the uC only to output MIDI clock data, then a start when the player starts cranking or reaches a certain minimum speed, and a stop when it stops or slows below a given lower limit.

Ha! I thought of doing the same with a motor driving a cam shaft hooked to a foot pedal with a potentiometer - the harder you press the faster the blast beat. Also thought of clutches or stops to change pattern or instruments.

Perfect setup for a one-man death metal band - just add guitar and mic. Kinda like Joe Buck Yourself or Pandiscordian Necrogenesis.

Deaht metal drum machine has a very power metal vibe to it, ironically enough :D
