Hardware

Boards and transports for building instruments that are the hardware and not a computer pretending to be one. The designs are open, so a product built on them is not built on a dependency that can disappear.

01 AudioBus Multichannel audio transport

Up to 64 channels of 32-bit audio, plus MIDI and control data, down a single twisted pair. Daisy-chainable, self-clocking and deterministic, built from parts that cost a couple of euros instead of proprietary silicon. For distributed instruments, multi-speaker installations and modular systems that need to stay in sample lock.

  • Up to 64 channels at 32 bits
  • One twisted pair per link, daisy-chainable
  • MIDI, SPI, I2C and GPIO tunnelled alongside the audio
  • Commodity parts, no licensing
02 MPE touch controller Expressive keyboard

A multitouch MPE keyboard on a seven-inch panel: two rows of keys with snap-to-pitch, glide, slide and pressure, streaming RTP-MIDI and OSC over wifi to anything on the network. The touch layer runs at 250 Hz so expression tracks the finger and not the frame rate.

  • Per-note bend, pressure and timbre
  • Snap-to-pitch, glide and slide
  • RTP-MIDI and OSC over wifi
  • 250 Hz touch, 60 fps interface

Working together

The designs are open, and I take on product work around them: instrument platforms, networked audio, and firmware that has to keep time.
