One Plaits.
Unlimited colors.

Plaits Palette is a free browser tool for building your own custom Plaits firmware — a way to widen and deepen what the module can do, and make it your own. Choose a model for each of Plaits' slots: stock models, experimental Rubato Labs models, and community contributions. Then set your firmware options and generate an audio-installable build.

Close to the 224 KB flash limit. This is a measured-size estimate that can run slightly low on full palettes, so leave a little headroom — the ARM build is the source of truth.

Firmware options

Model navigationHow the two buttons move between models. Built into the firmware, not shown in the module’s options menu.

The left button steps backward and the right button forward, through every model one at a time. Walking off the end of a bank lands in the next one.

Try it — these buttons work like the module’s.

Starting optionsWhere your firmware starts. Everything here stays editable on the module.

On the module you reach these by pressing both buttons at once. The first seven lights become the menu: the left button steps to the next light, the right button changes its setting, and both together save and exit.

  1. Which set of chords the chord-reading models play.

  3. Dark until the aux output is a suboscillator — the module steps straight past it.

  8. UnusedAlways dark
AdvancedHardware, accessibility, and recovery

Turn this on only for a Ro’Ved. It replaces Plaits’ two-button controls with Ro’Ved’s four clickable knobs; the synth models, banks, chord tables, and other firmware options stay the same.

Every model light uses one hue, with brightness identifying the bank: the first bank is brightest, followed by bright, dim, and — for the optional fourth bank — dimmest.

This is built into the firmware, so there is no power-up gesture and the calibration startup gesture stays available. The slower selected-model pulse still works independently. The options menu also uses brightest, medium, and dim instead of relying on hue.

Leaving the procedure out leaves more space for synth models.

Turn this on if your module has never been calibrated (fresh DIY build) or if your module doesn't appear to respond accurately to V/OCT. With it on, hold the right button while powering the module up: the first light pulses green, and you patch 1V into V/OCT and press a button. It turns yellow; patch 3V and press again. If the two voltages aren't two octaves apart, every light flashes red and nothing is saved.

Remember, calibration data isn't touched by firmware updates. So if you need to calibrate, you can always enable it once, and then build another firmware without the procedure to reclaim that space and use it for models.

For flashing with a hardware programmer. For the usual audio update process, leave this off and use WAV.
