-Features:
-- 6 output channels
-- Master BPM
-- Separate divider or multiplier per chennel (from /32 to x24)
-- Random (currently only for on beat pulses)
-- 1 input for external modulation (currently hardcoded to channel 6)
-
-TODO:
-- random for any division (long press encoder)
-- External clock
-- Switch to U8G2 for screen
-- Save state to EEPROM when stopped
-- swing
-- settings (input mode, pulse length, modulation targets)
-- Design PCB
