Hamish Sandys-Renton

I build instruments, and the tools behind them.

Engineer working across the cloud, audio software and firmware. Lately: new firmware for a vintage drum machine, instruments built on Raspberry Pi, and software that helps musicians work together.

Selected work

    Machinedrum firmware

    New firmware for a 2001 drum machine. Six independent mono outputs, a compressor on every output bus, and the safety tooling to flash it without bricking anything.

    PiSampler

    A multi-voice hardware sampler and synth built on a Raspberry Pi, played from a Cirklon sequencer, with granular playback, a vocoder, a formant 'singer' voice and chaotic modulation.
