settings saved to EEPROM on play/pause

 - Separate divider or multiplier per chennel (from /32 to x24)
 - Per-channel random pulse skip (currently only 50/50 chance)
 - 2 inputs for external modulation (assignable per channel)
+- All channel settings and bpm are saved on play/pause and recalled on power up
 
 TODO:
 - different chance options for random
-- Save state to EEPROM when stopped
 - design PCB
 - external clock
 - swing
