ElectroTechnique TSynth - Teensy 4.1 based DIY Synthesizer
https://youtu.be/uCA2L7CeWSETeensy 4.1 based synthesizer using PJRC Audio Board and Audio Lib
The pcb and front panel are available from Tindie.com with SMD 4067 multiplexers, 6N138 opto-isolator, capacitors and resistors fitted. The entire cost of parts to build TSynth will be around $99 if you buy components from the cheaper suppliers and the build time around two hours to solder.

Mixer / Selectable filter / 2 DCA for main mix
Wavetable edition : Re-cycle, Normalize wavetables.
Hard sync between OSC
Frequency Mod / Phase Mod Capabilities between OSC
4 LFO Wavetables
4 ADSR
Noise
Clockable via gate input
Teensy 4.1 board (600mhz CPU overclocked to 816mhz)
OLED Screen 256x64 (16 level grayscale)
16 Mb RAM for wavetables
48khz audio engine
4 endless pots (analog encoders) / 1 digital (quadrature) clickable encoder
(Direct recording, reverb has been added in post-recording)
