Timeline

The timeline is the central workspace. Tracks are stacked vertically, clips are arranged horizontally against a beat/bar ruler. Standard operations — drag, trim, split, copy, paste — work as expected.

​

Track Model

Each track has a single sound source — either an audio sample or an Audio Unit instrument — followed by an effects chain. One source, one chain, one output. Groups act as summing buses for their child tracks. They appear in the sidebar track list but not as rows in the timeline — only tracks that contain clips are shown.

​

Zoom Levels

The timeline uses three fixed vertical zoom levels instead of free zoom:

​

Focus Mode

Double-click a clip or press ⌥↓ to enter Focus Mode. This opens inline editing for piano roll, transient markers, and slice playback. Press Escape or ⌥↑ to return to the arrangement view.

​

Looping

A loop region repeats a section during playback. Toggle looping with ⌘L. Use ⌘⇧L to enable looping and zoom to the selected region. Looping is also used for loop recording.

​

Clip Creation & Deletion

Hold ⌘ and click on an empty area to create or stamp clips. The behavior depends on context: Drag after clicking to set the clip duration. New MIDI clips automatically enter Focus Mode for immediate editing. Right-click a clip to delete it. Right-click and drag to erase multiple clips in one gesture.

​

Clip Gain & Normalize

Every audio clip carries its own gain value, independent of the track fader. Select one or more clips and press a number key to set the gain relative to that clip’s own peak:

• 0 — normalize (peak reaches 0 dBFS)
• 1 – 9 — 10 % – 90 % of normalized peak
• ` / ^ — mute / unmute

Because each clip is measured independently, a mixed selection ends up at matching levels instead of sharing one global gain. MIDI clips are skipped. Time-stretched audio is measured across the full source span that actually plays, so sped-up drum loops normalize correctly. Boost is capped at +24 dB to keep very quiet tails from being amplified into walls of noise. Mute uses a dedicated flag, so unmuting restores the previous gain value.

​

Solo Dimming

When any track is soloed, non-soloed tracks are visually dimmed in the timeline. This makes it easy to see which tracks are active at a glance. The dimming applies to both clips and waveforms — soloed tracks keep their full brightness while everything else fades back.

​

Grid & Snapping

The grid resolution adapts to the horizontal zoom level. All operations snap to the grid by default. Hold Option while dragging for half-step precision.

​

Groove

A groove template shifts the timing grid to create swing or shuffle feels. Configure groove in the Project sidebar (⌘5) under Grid:

• Template — 38 presets across categories: Swing, Triplet, Hip-Hop, Funk, Breakbeat, and Complex
• Amount — 0–100% intensity of the groove offset

See Groove & Swing for details.
