WavetablePi is a wavetable module based on the Raspberry Pi Zero 2 W running mt32-pi. It is capable of emulating several midi synthesizers, including mt32, sc55 and general midi with custom sound fonts. For a complete feature list please refer to the mt32-pi project.

Features

It currently supports two modes of audio: using the raspberry pi's PWM audio out (which is noisy and sounds pretty bad), and an external Hi-Fi PCM5102A based DAC.
You can also attach a 0.91 OLED SSD1306 I2C 128x32 display.
