Drumulator : with RISC-V processors.

For now, I'm working on the analog output board of the Drumulator. After testing the feasibility of my concept, with the help of a few off-the-shelf boards, I'm starting to draw up the schematic diagram for the audio section of the Drumulator.

The schematic isn't complete yet, but there are already number of components.

This shouldn't take up too much PCB space, though. One of the dimensions will be dictated by the alignment of the audio connectors.
