Sweep Automation
A sweep node lets you record parameter changes in real time — perform live pad movements during scene playback, and the captured gestures become automation curves.
How It Works
Section titled “How It Works”- Arm recording — tap the ● button on a sweep node in the scene view, or in the sweep editor toolbar
- Touch any parameter — drag an FX pad, Master pad, EQ node, or track knob. Playback starts automatically and recording begins
- Perform — move pads and toggle effects as you normally would. Every movement is captured
- Stop — tap ● again or stop playback. Curves are written to the sweep node
Sweep nodes are auto-generated when you record — no need to create one manually first.
What Gets Recorded
Section titled “What Gets Recorded”| User Action | Recorded As |
|---|---|
| Drag FX pad (verb, delay, glitch, granular X/Y) | Continuous curve |
| Drag Master pad (comp, duck, ret, sat X/Y) | Continuous curve |
| Drag Filter pad (cutoff, resonance) | Continuous curve |
| Drag EQ nodes (freq, gain, Q) | Continuous curve |
| Drag track volume/pan knobs | Continuous curve |
| Drag voice parameter knobs | Continuous curve |
| Drag send level knobs | Continuous curve |
| Toggle FX on/off | Toggle curve |
| Toggle FX hold | Toggle curve |
| Toggle track mute | Toggle curve |
Sweep Editor
Section titled “Sweep Editor”Open the sweep editor by selecting a sweep node → Dock panel → edit. The dark-zone editor shows:
- Curves section — labeled mini-curves for each recorded parameter
- Toggles section — colored blocks (ON = accent color, OFF = dark gap)
- Canvas — timeline with playback cursor, zoom via scroll/pinch
Editing
Section titled “Editing”| Action | Effect |
|---|---|
| Click a curve in the list | Select it for editing |
| Drag control points | Reposition on the curve |
| Double-click a point | Delete it |
| Click on the curve line | Add a new point |
| Shift+drag on canvas | Select a range of points |
| Delete/Backspace with range | Remove points in range |
| Drag range edges | Adjust trim boundaries |
| Select a point → use T/V knobs | Precision time/value control |
Playback Preview
Section titled “Playback Preview”During scene playback, an amber cursor sweeps across the canvas. A gradient trail follows the cursor with curve crossing dots.
The Clear button fades out and removes all curves (including global sweep data).
Global vs Chain Scope
Section titled “Global vs Chain Scope”Parameters are automatically routed to the correct scope:
| Scope | Targets | Meaning |
|---|---|---|
| Global | Master, FX, EQ, Filter, FX on/off, Hold | Plays across entire scene duration |
| Chain | Track volume/pan, voice params, sends, mute | Plays only during the connected pattern’s chain |
Overdub
Section titled “Overdub”Re-recording merges with existing data:
- Touched parameters are overwritten with the new recording
- Untouched parameters keep their existing curves
Recording Preview
Section titled “Recording Preview”During recording, a thin sparkline strip appears above the performance pads, showing real-time traces of the parameters being captured.
Scene View
Section titled “Scene View”The sweep node appears as a generator-sized card with:
- A curve preview showing all recorded curves
- The target pattern name (e.g., → FROST)
- The number of active curves
- Use with Repeat nodes — a Repeat ×6 node gives you 6 repeats to sweep across. Without a repeat node, the sweep spans a single pattern play-through.
- Layer multiple parameters — move several pads in one recording pass to create complex evolving textures
- Overdub in passes — record filter first, then reverb sends in a second pass. Each pass only overwrites what you touch.
- Undo — Ctrl+Z restores sweep data to the pre-recording state
