The D-03 Arpeggiator is a subtractive synthesizer that generates rhythmic polytonal music. It was programmed using a Retrosmith Daisy Seed and Arduino IDE. It uses three oscillators to produce different voices with independent pitch control. A range of analogue effects are available including BPM, reverb, and delay. It can also switch between two different wave forms and an arpeggiating rhythm. The device is housed in a brushed steel case and includes a headphone port and micro USB power cable.

Designed in collaboration with Charlie Morton and Francesca Ramdhanie.
