The MIDI Unit is an all-in-one solution for channel control, audio synthesis, and seamless MIDI interfacing. Tailored for real-time music performance, studio production, and interactive installations, this compact module brings together MIDI signal management, on-board sound generation, and adaptable connectivity, making it a valuable part of any MIDI-focused audio workflow. Key Features of MIDI Unit Integrated SAM2695 Audio Synthesizer Built around the powerful SAM2695 chip, this module handles direct MIDI-to-sound conversion, generating rich, expressive tones with no need for extra hardware devices. Full MIDI 1.0 Protocol and UART Support The MIDI Unit ensures universal compatibility with all MIDI 1.0 devices, making communication with synthesizers, controllers, and other gear effortless and reliable. Easily connect to M5Stack or other systems using standard UART. Dual Signal Routing Modes Easily toggle between Bypass mode—direct left/right channel passthrough—and Separate mode, which allows each MIDI port to operate independently for complex signal flows. Versatile I/O Options Both MIDI ports offer support for DIN 5-pin and 3.5mm TRS connections, guaranteeing broad compatibility with your instruments and DAWs. Grove Port for MIDI Monitoring and Output The TXD (Grove) connects to the left MIDI port for monitoring or external control, while the RXD pin lets you trigger the built-in SAM2695 synth from an external controller or microcontroller host. Optocoupler Protection Internal optocoupler isolation shields your workflow from interference and ensures signals stay clean and digitally accurate, even in complex setups. Direct 3.5mm Headphone Output Instantly listen to your MIDI sequences through the 3.5mm audio output, with no other adapters needed for fast monitoring or stage output. Includes 1x MIDI Unit 1x HY2.0-4P Grove cable (20cm) Typical MIDI Unit Applications Music Creation – Seamless fit for MIDI gear, DAWs, and synth rigs—perfect for sound design or production. Stage Control – Ideal for performance automation, instrument switching, and complex live setups. Interactive Sound – Excellent for smart music installations, IoT sound systems, and creative audio projects. Why MIDI Unit Stands Out The MIDI Unit offers robust MIDI integration, flexible routing, and quality sound synthesis in a pocket-sized device. Whether you’re building elaborate stage rigs, composing in the studio, or designing digital installations, it empowers you to explore, control, and innovate without boundaries.
