Review: the J2B Synthesizer tested and assembled by professionals
That Cortex M3 is so musical… The J²B Synthesizer was developed from the Atmegatron music synthesizer by Soulsby Synthesizers. This design appealed to Elektor designer Clemens Valens so much, that he had to do something with it. The J²B Synthesizer is a port of the open-source sound-generator firmware in the Atmegatron, to firmware which runs on an LPC1347, a 32-bit ARM Cortex-M3. And of course, this more powerful microcontroller offers more functionality than what is possible with the simpler ATmega328, which is in the Atmegatron.
