The MIDI Unit is a channel control and audio synthesis device based on the MIDI interface. A switch on the front lets you set the left and right MIDI ports to either Bypass or Separate mode. In Bypass mode, the left and right ports are directly connected, while in Separate mode, they operate independently. Both MIDI ports support standard 5-pin DIN and 3.5mm headphone connectors.
The TXD pin on the Grove port is connected to the left MIDI port signal, and the RXD pin is linked to the internal audio synthesizer’s SAM2695 digital input. This setup allows an external M5 host to monitor or send MIDI signals through the Grove connector while simultaneously outputting synthesized audio. The audio signal is output via a 3.5mm headphone jack.
This MIDI Unit is great for electronic music creation and production, live music control, and interactive music installations.
