Did you set the particular options available in the “Rec Mode” menu (located in the tools bar to the right)?
Below please find the description about the available modes (snippet from the in-app help).
There are 4 recording options available, which you can combine.
- Punch in: Recording will only start once the playhead reaches the left locator.
- Punch out: Recording will stop once the playhead reaches the right locator, but playback will continue.
- Pre-Roll: The song will be played back during precount.
- Count in: The metronome will be audible during precount.
