A monophonic synthesiser comprised of an LFO, VCO, and Delay. The synthesiser is controlled by 9 potentiometers and 3 buttons. Configurations can be stored to 1 of 10 preset keys. Pressing a preset key will override the potentiometers and buttons with the stored configuration.
The processor used is PIC32MZ. This is a 32-bit device with a FPU, 512 KB of RAM, 2 MB of program space, running at 252 MHz. The processor is deliberately over-spec'd to simplify development and allow new ideas to be explored in the future. The DAC is a 24-bit 192 kHz stereo device configured for 96 kHz mono.
