From the project
Ribbon Synthesizer using Daisy Seed.
A touch-controlled FM ribbon synthesizer built on the Electrosmith Daisy Seed platform. Pitch is controlled by a 150mm soft-pot ribbon sensor; expression by a force-sensitive resistor. A panel of knobs and switches shapes the FM synthesis, distortion, filter, tremolo, and reverb.
