From the project

Software and hardware files for the TES 10k synths serie, cheap synthesizer powered with Mozzi using a STM32 BluePill as its main chip

10 knobs synths are simple synthesizers based on Mozzi using STM32 blue pill with 10 knobs. Different versions are available:

- 10knobsmono24bitsMCP4822 is a mono synth built around the MCP4822 dual DAC, with theoritical 24 bits resolution (in practice, around 14/16 bits get outside the noise, but that is already quite a lot). It can easily be turned into a stereo synth with 12bits on each channel. - 10knobsmono16bitsPT8211 is a mono synth built around the PT8211 dual DAC, with theoritical 16 bits resolution. This one can easily be upgraded to a stereo version: only one channel of the PT8211…
