Place and join sample cuts by hand

Double-click the waveform to add a cut. Drag its upper handle to move it. To join two Chops, double-click the cut between them or click its floating X. Joining keeps all the audio; it only removes the cut.

Useful when Auto Chop gets close but a phrase needs a cut in a particular musical spot. Zoom in when cuts are close together, then zoom out and listen.

For S9 Sampler 0.1.6 (paid beta). More help inside the app: Help & Shortcuts → Waveform & cuts.

Step by step

  1. Zoom and move around

    Use the wheel or pinch to zoom and Shift-wheel to scroll, or drag the overview. Expand gives the waveform more room.

  2. Add a cut

    Double-click where you want it. Play both new Chops and nudge the cut if needed.

  3. Move or join

    Drag the upper handle to move a cut. Double-click it, or click its X, to join the two Chops.

  4. Delete only on purpose

    Delete Chop and Audio removes that section and closes the gap. Use Undo if you meant to join instead.

Good to know

Check Key Map after big changes

Adding or joining Chops can change which key plays what. Open Key Map before you carry on with a MIDI pattern.

Previews have their own Undo

An Auto Chop preview and the main waveform keep separate Undo history.
