An Arduino C++ library for building MIDI controllers and control surfaces, with a flexible MIDI abstraction layer supporting 5-pin DIN, USB, and BLE MIDI. It provides ready-made utilities for potentiometers, buttons, encoders, LEDs, displays, and port expanders like multiplexers and shift registers.

Use cases

• build a diy midi controller with arduino
• read potentiometers and send midi cc messages
• create a midi control surface for a daw
• send and receive midi over usb or ble on esp32
• drive leds and displays from incoming midi messages
• expand gpio with multiplexers and shift registers for many controls

When to choose

• you're building a MIDI controller or control surface on Arduino, Teensy, ESP32, or RP2040
• you need a unified API across DIN, USB, and BLE MIDI interfaces
• you want high-level abstractions for buttons, faders, encoders, and MIDI feedback

When to avoid

• you need a general-purpose MIDI sequencer or DAW software rather than hardware controllers
• your project isn't on a supported Arduino-compatible board
• you need non-MIDI embedded audio processing
