M5Stack MIDI Unit Serial to MIDI Unit 3.5nn Interface SAM2695 for Channel Control and Audio Processing

M5Stack MIDI Unit Serial to MIDI Unit 3.5nn Interface SAM2695 for Channel Control and Audio Processing

Description:
- MIDI Unit is a channel control and audio synthesis unit based on the MIDI interface. The switch on the front of the product allows you to set the left/right MIDI port's bypass mode. In Bypass mode, the left and right ports are directly connected; in Separate mode, the left and right ports are separated. The left and right MIDI ports support both standard 5-pin DIN and 3.5mm headphone interfaces. The TXD pin on the Grove port is connected to the left MIDI port signal, and the RXD pin on the Grove port is connected to the internal audio synthesizer's SAM2695 digital input. This allows an external M5 host to monitor or output MIDI signals through the Grove interface while simultaneously outputting synthesized audio. The audio signal is output through a 3.5mm headphone jack. This product is suitable for electronic music creation and production, live music control, and interactive music installations.

Specification:
- Separated Mode:
1.Unit MIDI RX (Controller's TX pin) is connected to the SAM2659 synthesizer chip and the OUTPUT interface.
2.Unit MIDI TX (Controller's RX pin) is connected to INPUT, but this pin is floating and has no function in this mode.

- Bypass Mode:
1.Unit MIDI RX (Controller's TX pin) is connected only to the SAM2659 synthesizer chip.
2.Unit MIDI TX (Controller's RX pin) receives MIDI signals from INPUT, and INPUT is directly connected to OUTPUT.
