M5Stack Midi Unit with DIN Connector (SAM2695)

The MIDI Unit is a MIDI interface-based channel control and audio synthesis module, designed for electronic music creation, live performance control, and interactive music installations. This compact and powerful module integrates MIDI signal processing, audio synthesis, and versatile connectivity, making it an excellent addition to any MIDI-based music production setup.

Key Features of MIDI Unit

• Integrated SAM2695 Audio Synthesizer
  Equipped with a SAM2695 audio synthesizer chip, the MIDI Unit supports real-time MIDI-to-audio conversion, generating high-quality synthesized sound without additional hardware.
• Standard MIDI 1.0 Protocol & UART Communication
  The MIDI Unit is fully compatible with MIDI 1.0 protocol, enabling seamless integration with a wide range of MIDI controllers, synthesizers, and music equipment. It supports UART communication, allowing easy interfacing with M5Stack and other microcontrollers.
• Dual-Mode MIDI Signal Routing
  The MIDI Unit features a switchable left/right MIDI port bypass mode: Bypass Mode – The left and right MIDI ports are directly connected for seamless signal flow; Separate Mode – The left and right MIDI ports operate independently for advanced routing and signal processing.
• Flexible MIDI Connectivity
  The left and right MIDI ports support both standard 5-pin DIN and 3.5mm TRS (headphone jack) MIDI interfaces, offering broad compatibility with various MIDI devices and digital audio workstations (DAWs).
• Grove Interface for MIDI Signal Monitoring & OutputTXD pin (Grove port) connects to the left MIDI port, allowing external devices to monitor or send MIDI signals.RXD pin (Grove port) links to the internal SAM2695 synthesizer, enabling external M5 hosts to control MIDI playback and generate sound.
• Optocoupler Isolation for Reliable Signal Processing
  Built-in optocoupler isolation ensures electrical noise reduction and signal integrity, preventing unwanted interference when integrating with other MIDI devices.
• 3.5mm Audio Output for Direct Sound Playback
  The MIDI Unit supports direct audio output via a standard 3.5mm headphone jack, allowing users to listen to synthesized MIDI sound without additional converters.
