@ -3,17 +3,16 @@ Features:
- Master BPM
- 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 (currently only 1, hardcoded to channel 6)
- 2 inputs for external modulation
TODO:
- per-channel modulation settings
- different chance options for random
- External clock
- Save state to EEPROM when stopped
- design PCB
- external clock
- swing
- Switch to U8G2 for screen
- settings (input mode, pulse length)
- Design PCB
