A summary of the basic gestures for working with clips on the timeline.

Goal -> action

Goal	Action

Move a clip	Drag the clip body (left/right for time, up/down for track)
Resize a clip	Drag the left or right edge handle (1 beat minimum)
Duplicate a clip	Select and press Cmd/Ctrl + D
Split a clip	Switch to Slice tool (2), click on the clip
Merge clips	Switch to Merge tool (3), click on overlapping/adjacent clips
Stamp clips	Copy a clip, switch to Stamp tool (4), click or drag at the target position

Tool switching

Switch tools with the toolbar above the timeline or with number keys (customizable in Shortcuts).

Key	Tool	Role
1	Select	Select / move / resize
2	Slice	Click to split
3	Merge	Click to merge
4	Stamp	Click to stamp repeatedly

Create a clip

With the Select tool, double-click an empty area in a lane to create a clip there. The position snaps to integer beats. After creation, double-click the clip to open the piano roll for note editing or coding.

Selection

• Click — single select
• Shift + click — add to selection
• Cmd/Ctrl + click — toggle selection
• Drag in empty space — marquee select (clips fully inside are selected)
• Hold Shift / Cmd/Ctrl during marquee to add to existing selection

Move and resize

• Drag the body to move in time and across tracks. With multiple selected, all move together.
• Drag the left/right edge handle to change length. Minimum 1 beat, cannot exceed the project end.
• Drag positions snap to integer beats.

Resize is non-destructive

Shortening a clip does not delete its notes or CC data. Playback only sounds the new length, and re-extending the clip brings hidden notes back.

Slice

Press 2 for the Slice tool, then click the clip at the split point. The clip becomes two; notes and CC are kept on both sides (a non-destructive split that only changes the playable range). Each half is at least 0.25 beat wide.

Merge

Press 3 for the Merge tool:

• If multiple clips are selected, the same-track clips among them are merged into one.
• If nothing is selected, clicking a clip auto-detects adjacent or overlapping clips and merges them.

The merged clip keeps every source clip’s notes and CC, with each note recomputed relative to the new clip’s start.

Stamp — repeated placement

Useful for laying down a repeating pattern:

1. Select the source clip and Cmd/Ctrl + C to copy
2. Press 4 for the Stamp tool
3. Click at the target position to place one copy; drag to place several in a row

If nothing was copied, the currently selected clip is used as the stamp source.

Duplicate / Copy / Paste

Shortcut	Action
Cmd/Ctrl + D	Duplicate immediately after on the same track
Cmd/Ctrl + C	Copy to clipboard
Cmd/Ctrl + V	Paste (placed at the playhead)

Delete

Press Delete or Backspace with one or more clips selected. Selection is cleared after deletion. Cmd/Ctrl + Z to undo.
