Using a Footswitch
The footswitch connector on Mbox Pro lets you
use a footswitch pedal to control either playback
start/stop or recording punch in/out. Both
QuickPunch audio punch-in and punch-out
and MIDI punch-in and punch-out recording
are supported.
The footswitch connector is designed specifi-
cally for instantaneous (momentary) on/off
pedals with a 1/4-inch TS connector. Continu-
ous on/continuous off pedals can also be used,
but may result in unexpected behavior.
To use a footswitch control:
1 Connect a footswitch to the footswitch con-
nector on the back panel of the Mbox Pro.
2 Launch Pro Tools.
3 Choose Setup > Hardware.
4 Select Record Punch In/Out or Playback
Start/Stop.
