Pro Tools:punch in record

Pro Tools punch in record
To punch in on Pro Tools you must have either Quickpunch or Trackpunch enabled.

Quickpunch
To enable quickpunch right click the transport record button and choose Quickpunch

Trackpunch
To enable Trackpunch right click the transport record button and choose Trackpunch

The difference between Trackpunch and Quickpunch is Trackpunch enables you to drop in and out on different tracks at different times within the same pass. Quick Punch won't do this, it will only drop in and out on all the selected tracks at the same time

With either of these modes enabled you can now record "on the fly" by pushing Command>Spacebar (Mac) or Control> Spacebar (Windows) while record enabled tracks are playing.
