1. Accordéon Diatonique
3 MIDI actuator proposals
Overview
Three solutions for MidiCore to physically actuate your Accordéon Diatonique via received MIDI signals.
Proposal A — Button Solenoids
Solénoïdes JF-0530B 12V
Automatic actuation of each button via Note On — automated playing and robotic compositions
Proposal B — Bellows Servomotors
Micro-servos SG90 + courroie
Automatic bellows control (amplitude, speed) via CC11 — programmed expression
Proposal C — LED Haptic Feedback
LEDs WS2812B + moteurs vibration 3V
LEDs under each active button + vibration feedback — real-time visual/tactile feedback
MidiCore Configuration
// Actuators Accordéon Diatonique #define MODULE_ENABLE_DOUT // digital outputs #define MODULE_ENABLE_AOUT // analog outputs (PWM) // Note On → actuator ON · Note Off → OFF // CC11 → intensity (0-127 → PWM 0-255) // Output latency : <3ms
Comparison
| Proposal | Type | Complexity |
|---|---|---|
| A | Button Solenoids | ★★★ |
| B | Bellows Servomotors | ★★ |
| C | LED Haptic Feedback | ★ |
