Chapter 5: Using Pro Tools | Duet 26
Lowering the Latency
While recording, if you notice a delay between the moment you play or sing a note and when you hear it in your headphones you
are experiencing latency.
To configure the Low Latency Mixer:
1 Once all inputs are set up, disable software monitoring in DAW.
2 Go to Output Tab in Pro Tools IO Control and choose Mixer under Speaker or Headphone Out selection.
Input signal should be heard in Speakers or Headphones.
3 Go to Mixer Tab to control volume, mute and solo of input.
Setting Sample Rate
Pro Tools | Duet operates at all standard sample rates between 44.1 kHz and 192 kHz. In most cases, the sample rate is set by the audio
application with which Pro Tools | Duet is communicating. For those audio applications that don’t include a sample rate setting,
such as iTunes, Pro Tools | Duet’s sample rate may be set in Audio MIDI Setup or on the System Setup tab of Pro Tools IO Control.
