What's New

In v0.6.0, a deep optimization pass on Plaits' audio thread, Marbles' MIDI clock sync calculation, and the MIDI over USB thread resulted in a massive decrease in CPU requirements, a reduction in latency from ~25ms to ~8ms, and a smart clock delay compensation algorithm for Marbles. Wakes is now a fully playable and sync-able MIDI instrument, ready to play along with other instruments.

Flashing

Read docs/SAFETY.md first. The SP-1 has no hardware reset pin.

  1. Open https://solderless.engineering in a browser and connect the SP-1 over USB-C.
  2. Hold Track 1 + Track 4 while plugging in. The four track lights go solid.
  3. Select wakes-sp1-v0.6.0.bin, flash, then unplug and replug.

wakes-sp1.bin is the same file under a fixed name, for the README's download link.
Check the file against SHA256SUMS before flashing.
wakes-sp1-v0.6.0-fallback.bin is the test-tone build without Plaits or Marbles,
for diagnosing hardware only. It is not the instrument.
