VoltSeq Cheat Sheet
Quick reference for Catalyst VoltSeq. See Catalyst VoltSeq for full documentation.
Default state on boot and after exiting any modal. Play, navigate pages, and edit steps directly.
| Action | Result |
|---|---|
| Play/Reset | Toggle play / stop |
| Shift + Play (tap, < 600 ms) | Reset all channels to step 1 |
| Hold Page N + turn Enc M | Edit channel M step at position N |
| Hold multiple Page buttons | Edit same enc across all held steps simultaneously |
| Turn Enc M (no page held) | Focus chaselight on channel M (no step edited) |
| Shift + Page N | Navigate to page N |
| Hold Chan. | Encoder LEDs show channel type colors (CV = grey, Gate = green, Trigger = green/teal) |
| Chan. + Page N | Arm channel N |
CV step editing: ~1 semitone per detent. Hold Fine for sub-semitone. Fast spin accelerates.
Gate step editing: gate length 0–100%. Trigger step editing: ratchet/repeat count.
Per-channel settings: type, length, direction, clock division, voltage range, and more.
Entry: Shift + Chan. (short tap — release before 1 s)
Exit: Shift + Chan. or Play/Reset
Press a Page button to focus a channel. Chaselight shows that channel's playhead.
| Enc | Panel label | Parameter |
|---|---|---|
| 1 | Start | Output delay (0–20 ms) |
| 2 | Dir. | Direction: Forward / Reverse / Ping-Pong / Random |
| 3 | Length | Step length 1–64 |
| 4 | Phase | Phase rotate (destructive) |
| 5 | Range | Voltage span (CV) / Pulse width ms (Trigger) |
| 6 | BPM/Clock Div | Per-channel clock division |
| 7 | Transpose | Floor voltage (CV only) |
| 8 | Random | CV deviation range: CW = unipolar (+N V), CCW = bipolar (±N V), 0 = off |
Shift held: Page buttons show current page indicator instead of chaselight.
Focus on a single channel for detailed step editing and real-time slider recording.
Entry: Chan. + Page N
Exit: Chan. + Page N again, or Play/Reset
CV channel
| Action | Result |
|---|---|
| Enc N | Edit step N CV value |
| Fine + Enc N | Sub-semitone editing |
| Slider | Record CV into current step (motion-gated) |
| Shift + Enc 5 | Adjust voltage span (Range) |
| Shift + Enc 7 | Adjust floor voltage (Transpose) |
Gate channel
| Action | Result |
|---|---|
| Tap Page N | Toggle step N on / off |
| Enc N | Adjust gate length for step N |
Trigger channel
| Action | Result |
|---|---|
| Tap Page N | Toggle step N between rest and single trigger |
| Enc N CW | Increase ratchet count (subdivide, 1–8×) |
| Enc N CCW | Increase repeat count (extend, 1–8×) |
Adjust glide time, gate lengths, pulse width, and per-step ratchets. Works in both main and armed mode.
Hold Glide
Unarmed — channel-level adjustments
| Channel type | Action | Result |
|---|---|---|
| CV | Glide + Enc N | Glide time for channel N (0–10 s) |
| Gate | Glide + Enc N | Offset all gate lengths for channel N |
| Gate | Glide + hold Page N + Enc M | Set ratchet count for step N on channel M |
| Trigger | Glide + Enc N | Pulse width for channel N (1–100 ms) |
| Trigger | Shift + Glide + Enc N | Offset all ratchet/repeat counts for channel N |
Armed — per-step glide time (CV)
| Action | Result |
|---|---|
| Glide + Enc N | Set glide time for step N; encoder LEDs show brightness = glide amount |
| Glide + Enc N CCW to minimum | Disable glide for step N |
Armed — per-step ratchet count (Gate)
| Action | Result |
|---|---|
| Glide + Enc N | Set ratchet count for step N; encoder LEDs show ratchet counts |
Per-step probability of a step firing, and random CV deviation amount. Active while armed.
Hold Shift + Glide while armed
Encoder LEDs show a violet → grey → white ramp — violet = 0% (always fires), white = 100%.
| Action | Result |
|---|---|
| Shift + Glide + Enc N CW | Increase probability for step N |
| Shift + Glide + Enc N CCW | Decrease probability; fully CCW = 0 (always fires) |
Gate / Trigger: non-zero probability suppresses the step's output randomly.
CV: non-zero probability applies a random voltage offset. Deviation range and polarity set in Channel Edit enc 8.
Phase Scrub orbit engine for live performance — granular looping and beat repeat.
Entry: hold Fine + Glide for 1.5 s
Exit: Play/Reset (saves performance settings automatically)
| Control | Function |
|---|---|
| Slider | Orbit center position |
| Page N | Toggle channel N orbit follow on/off |
| Shift held | Freeze orbit center (beat-repeat staging) |
| Shift + Page N | Navigate pages |
Settings shown on entry (encoder LEDs):
| Enc | Parameter | LED |
|---|---|---|
| 1 | Quantize orbit center | Orange = on |
| 2 | Mode | Off / green (granular) / blue (beat-repeat ×8) / cyan (beat-repeat ×4) |
| 3 | Granular width or beat-repeat debounce | Dim→bright orange / dim→bright white |
| 4 | Orbit direction (granular only) | Green / blue / orange / lavender |
| 8 | Phase Scrub Lock | Red = locked; blinks red during pickup |
Short Fine + Glide (release before 1.5 s): toggle Phase Scrub Lock from main mode or within Performance Page.
Clear step data from individual channels, or commit all changes to flash.
Entry: hold Fine + Play for ~500 ms — page buttons fast-blink to confirm
Exit: Play/Reset
| Action | Result |
|---|---|
| Page N | Clear steps + glide + probability for channel N (preserves channel settings) |
| Shift + Page N | Full factory reset for channel N (steps + flags + all channel settings) |
Multiple channels can be cleared before exiting.
No data is written to flash automatically except Performance Page settings.
Save gesture: hold Glide, then press and hold Chan. — page buttons fast-blink during hold, then blink 6× to confirm.
Glide must be pressed first. Pressing Chan. first shows channel type colors instead and does not save.
System-wide settings: play/stop reset behavior, master loop length, and internal BPM.
Entry: hold Shift + Chan. for 1 s
Exit: Play/Reset
| Enc | Panel label | Parameter | LED |
|---|---|---|---|
| 1 | Start | Play/stop reset mode | Red = on (Stop also resets all channels) |
| 3 | Length | Master loop length (0 = off; all channels reset together every N 16th-note steps) | Off / orange / red at bar-aligned values (8, 16, 32, 48, 64) |
| 6 | BPM/Clock Div | Internal BPM | Color zone: red < 50 / orange 50–79 / yellow 80–99 / green 100–119 / blue 120–149 / teal 150–179 / lavender 180+ |
Switch between Catalyst Sequencer and Catalyst VoltSeq without reflashing.
| Combo | Result |
|---|---|
| Hold Shift + Tap Tempo + Chan. for 1 s | CatSeq → VoltSeq |
| Hold Fine + Play/Reset + Glide for 1 s | VoltSeq → CatSeq |
Mode is saved to flash. Switching does not erase the other mode's data.
