The MIDI 1.0 Human Clock is an automated bridge between heart rate sensors and MIDI hardware. It synchronizes musical tempo to human physiology in real-time.
Operation
- Auto-Scan: On boot, the app scans for any available BLE Heart Rate Monitor (HRS).
- Connect & Sync: It automatically connects and subscribes to BPM notifications.
- Clock Generation: Converts the heart rate into a high-precision 24 PPQN MIDI Timing Clock.
- Dual Output: Transmits the clock simultaneously via Serial MIDI 1.0 and USB MIDI 2.0 (UMP).
- Monitor: Tracks and displays incoming MIDI messages (Notes, CC, Pitchwheel) and BPM stability (PLL) on the integrated LCD.
Features
- BLE: Supports Coded PHY (Long Range) for robust sensor connectivity.
- Precision: Hardware-assisted MIDI clock generation and measurement.
- UI: LVGL-based dashboard with BPM history charts and a MIDI message log.
- Zephyr board with BLE (e.g., frdm_rw612, frdm_mcxw71).
- LCD display (e.g., lcd_par_s035_spi).
- Zephyr MIDI1 module.
