So you find yourself wanting to loop an audio file in Pro Tools and even though you Loop play enabled the audio selection doesn’t seem to be looping. I created a really short video to help you solve the problem:
Loop Playback Not Working Tutorial
Basically you can’t have Quick/Punch switched on and have a track armed. You have have to make sure either Quick/Punch is switched off, or you have no tracks record enabled. Once this has been done you should be able to loop until your hearts content.
You may also be trying to loop a selection that is too short. The limitation on Pro Tools is under half a second, or 500ms. I don’t know why anyone would do this, but it is worth noting.
I hope that helps! I will be coming out with plenty more Pro Tools tutorials over the next few months so Subscribe to my Youtube channel to stay updated.
