Symptoms

Sometimes when you choose Process > Time Stretch on an Apple Loop in a Soundtrack Pro multitrack project, the results may not sound like you expect.

Resolution

Replace the Apple Loop with a WAV file format.

2. Replace the Apple Loop in the timeline with the WAV file, then choose Process > Time Stretch again.
