ReWire : Looping Playback with ReWire
Looping Playback with ReWire
Because Pro Tools | First does not offer separate loop markers as found in other third-party applications such as Reason, if you want to loop playback, do one of the following:
To loop playback in Pro Tools | First:
1. In the Pro Tools | First Timeline, select the time range that you want to loop.
2. Begin playback by pressing the Spacebar or clicking the Play button in the Transport.
To loop playback within a ReWire client sequencer:

With playback stopped, specify the loop within the ReWire client application and begin playback.

If you create a playback loop by making a selection in the Pro Tools | First Timeline, once playback is started, any changes made to loop or playback markers within the ReWire client application will deselect the Pro Tools | First Timeline selection and remove the loop.
