Degenerator 2 Polyphonic DIY Synthesizer & Sampler

Hello dear DIY friends…
I’m working on a new project called Degenerator 2. It’s a polyphonic sampler and synthesizer based on Teensy 4.1 with 16MB sample ram and touchscreen. In 2011 I started developing my first monophonic sampler/synthesizer. The project was later given the name “Degenerator”.
The degenerator was based on the most powerful 8-bit MCU from Atmel at the time, the ATXMEGA128A1 with a 32MHz clock speed. It is now the year 2024 and it is time for a comeback but with a bit more power. A polyphonic (8 voices) sampler/synthesizer is planned based on a Teensy 4.1 MCU with 600MHz and 16MegaByte sampler RAM. The “Degenerator II” project has already taken its first steps (see video). However, there will be more controls and a 3.2" touch display (as in the video).

A small update to the file system. The patch parameters are now stored in a JSON file and can be expanded as desired. I’m using the JSON library in Arduino for this. Once again, most of the work is in the details and the graphical user interface.

The next step in Degenerator2’s development is the oscillator section. The oscillators will feature VA Synthes, Wavetable, and Sample Synthesis similar to the Jeannie Synthesizer.

Really nice use of dot board!!

Sounds great! I found myself singing along with Tears for Fears and a wonderful fade out.
