The Synth Unit is an audio module designed for MIDI sound systems, equipped with a SAM2695 audio synthesiser. It handles standard MIDI signals through serial communication, suitable for settings like live performances, music studios, electronic music venues, and STEAM educational programs.

This module offers audio synthesis, mixing, and sound effects processing capabilities. It features multi-channel instrument sound output, allowing for the simultaneous creation of multiple tones for varied musical effects. You can also adjust sound settings with tools such as a four-stage EQ and reverb to tailor audio characteristics.
