Automation

Draw how any control moves through the song.

Automation records how a control changes over time: a fader that rises into the chorus, a filter that opens across eight bars, a reverb that grows on the last word. Each automated control gets its own lane under the track, drawn in musical time so it stays in place when the tempo changes. Playback and export follow the same lanes, and the engine aligns every move with the audio even when effects add latency.

When to use it

Use it for anything you would otherwise do by hand on every pass: volume rides, pan moves, send levels into a reverb, an effect parameter that should change in one section, or an instrument control that opens over a phrase. Automation is the difference between a static mix and an arrangement.

Controls

Adding a lane

Open the parameter selector beside the G button on a track and pick a control. Channel level, pan and sends are always available. Every effect in the rack lists its parameters, grouped as the effect shows them, and the virtual instruments list theirs. A track can hold as many lanes as you need; each one shows and hides independently.

Managing lanes

Open the track’s automation button to see Lanes on this track, including hidden and bypassed lanes. Reading / Bypassed switches between the lane and the manual value. Shown / Hidden changes only visibility; hidden lanes keep playing. Delete removes a lane, and Undo brings it back. The overview stays available while you search for another parameter.

The track button shows the lane count and uses the accent color while any lane is reading, including hidden lanes. Track rows and automation lanes share the same timeline grid as you zoom.

Editing points

Click in a lane to add a point and drag a point to move it. Right-click a point to choose a ramp or hold, or double-click it to delete it. Values are shown in the control’s own units.

Manual override

Turning an automated control bypasses its lane so you can try a manual value without erasing the points. Resume the lane explicitly when you want automation to read again; stopping and restarting playback does not resume it.

LFO

A continuous lane can carry a modulation panel: a shape, a rate in beats or hertz, and a depth that adds to the drawn curve. The timeline previews the result, so a slow sine on a filter cutoff is visible before you hear it.

Tips

  • Automate the send into a reverb instead of the reverb’s mix when you want one voice to bloom while others stay dry.
  • Automation points stay at their song positions when you move or copy clips.
  • Frozen tracks keep their lanes; unfreeze to edit them again.
  • Master has no automation lanes yet. To fade or ramp the whole mix, nest every track in one group and automate the group’s fader and effects instead. Right-clicking a Master control says the same.

Changes

  • Fixed
    Instrument lanes come back with the instrument · 16 October 2026

    Switching an instrument track to audio and back used to delete its instrument automation lanes, LFOs included, and only Undo could bring them back. The lanes now stay with the track, hidden while it is audio, just like its MIDI clips. Deleting a track also clears it from any effect that used it as a sidechain source, so nothing is left waiting for a track that is gone.

  • Improved
    Master explains why it cannot be automated · 9 October 2026

    Right-clicking the Master fader or one of Master's effect controls used to open the browser's own menu, because Master has no automation lanes. It now says so and suggests the way around it: nest your tracks in a group and automate the group's fader and effects.

  • Improved
    Manage every automation lane from one overview · 3 October 2026

    The automation browser lists every lane on a track, including hidden and bypassed lanes, with separate reading and visibility controls and deletion you can undo. Track buttons show lane counts and reading status, and automation lanes share the sequencer's grid as you zoom.

  • Faster
    Less work while reading automation · 3 October 2026

    Effect automation uses less processing power in racks with several effects. Playback and vertical scrolling avoid unnecessary redraws of the timeline, and automation point controls do less work when zoom changes. Wet/dry adjustments also keep more effect processing in WebAssembly. Automation timing, curves and sound remain the same.

    Dense-project zooming and repeated control edits still need further performance work; this pass does not eliminate every playback interruption.
