The dsp-D8 source code
In the end of 2015 DSP Synthesizers decided to make the dsp-D8 drum chip code open source.
The code runs unmodified on ATmega328, Arduino Uno and Arduino Nano.
The code is provided as is and is free for non Commercial use.
No support is provided.
My work on these free synthesizers is based on donations from people.
If you find the code useful, please consider a $3 donation to keep future developments open source.
