Overview

This is the pixis slide, an 8 bit digital synthesizer based of the ESP32.

It has 4 waveforms:

• Sine
• Triangle
• Square
• Sawtooth

Other features include:

• USB Midi controller support
• Envelope Generator
• Low Frequency Oscillation (Modulo)
• Pentatonic scale slide

I was inspired to build this project after finding myself discouraged from trying physical synthesizers due to their high price tag.

If you want to learn more, I recommend reading this paper I wrote detailing my work and process.
