Catalyst VoltSeq — v1.5.0
VoltSeq is a second firmware personality for the Catalyst Sequencer panel. It turns the module into an 8-channel voltage recorder and step sequencer in the style of the Malekko Voltage Block — parameter lock, polyrhythmic, recordable with the Phase Scrub slider.
This release ships as a second WAV alongside the standard Catalyst Sequencer build. Both personalities live in the same firmware image; no reflashing is needed to switch between them.
See the wiki for full documentation.
What's in this release
- 8 independent channels — each with its own type (CV / Gate / Trigger), step length (1–64), clock division, and playback direction
- CV channels — stepped or slewed voltage, configurable voltage window (range + floor), optional quantizer scales, slider recording in real time
- Gate channels — variable gate length per step, per-step ratchet subdivisions, x0x-style step toggling
- Trigger channels — short pulse with configurable width, per-step ratchet (subdivide) or repeat (extend)
- Per-step probability — stochastic gate suppression (Gate/Trigger) or CV deviation (CV); edited per-step while armed
- Phase Scrub Performance Page — orbit engine and beat repeat ported from Catalyst Sequencer; per-channel follow toggle
- External clock — 1 pulse per 16th note at Clock In; resumes internal clock on removal
- Intentional save — all data written to flash only on explicit gesture (see below)
Switching personalities
No reflashing needed. Both builds (CatSeq+CatCon and CatSeq+VoltSeq) ship in this release.
Within the CatSeq+VoltSeq build:
- CatSeq → VoltSeq: hold Shift + Tap Tempo + Chan. for 1 second — all 8 channel LEDs blink to confirm
- VoltSeq → CatSeq: hold Fine + Play/Reset + Glide for 1 second — all 8 channel LEDs blink to confirm
Mode is saved to flash. Switching does not erase the other mode's data.
Saving
VoltSeq uses intentional saving — nothing is written to flash automatically (except Performance Page settings, which save on Performance Page exit).
To save: hold Glide, then press and hold Chan. Page buttons fast-blink during the hold, then blink 6 times to confirm. Glide must be pressed first — pressing Chan. first shows channel type colors instead and does not trigger a save.
Power-cycling without saving will lose unsaved changes.
