Cakewalk Project5: Time-stretch Groove Matrix clips to match tempo

- Drag a clip from the browser (revealed when you click on the Explore button) into a Groove Matrix cell.
- Right-click on the clip, and select Play in Time with Song. Make sure One-Shot is not selected.
- Assuming the clip is still selected (if not, click on it), click on the Editor button. The clip waveform appears in the Editor window.
- Add time-slice markers (shown by markers with green triangular heads) at a particular rhythmic value by clicking on the right/left arrow buttons in the Slice Division field until the field displays the desired value.
- Slices work best if they’re lined up with transients. If necessary, turn off Snap to Grid, click on a slice marker head that isn’t lined up properly, and drag it to just before a transient begins. Repeat for other slice markers that need adjustment.
- To add a slice marker, double-click in the area just above the waveform, at the place where you want the marker to appear. To remove an unneeded marker, right-click on it.
- Click on the clip name, and verify that the slicing works as desired—see Tips for additional information.
- If you hear “flamming” when stretching a clip, then you probably need to either add a marker at a transient, or move a marker to coincide with a transient.
- If part of a clip seems to speed up, it definitely needs another transient marker to indicate where a beat should fall.
- You can draw in pitch changes for individual slices. Select “Slice: Pitch” (to the right of the Automation Tool button), choose the Automation Tool (pencil), then draw the pitch automation curve directly on the waveform. This is definitely a cool effect!
