Chapter 5: Using Pro Tools | Duet 23
Clear Meters
The Clear Meters function will remove any peak and over indicators in Pro Tools IO Control and OLED meters on Pro Tools |
Duet’s front panel. If
Peak Hold or Over Hold (in the System Setup tab) is set to Infinite, all indicators will remain illuminated until
Clear Meters is engaged.
MIDI Input/Output
Mac
Pro Tools | Duet’s USB MIDI input/output provides a MIDI connection between class compliant Core MIDI devices such as key-
boards and other controllers and Apple’s Mac OS X.
A class-compliant MIDI device works with Core MIDI without the need to install drivers or other additional software.
To confirm that your MIDI device is class-compliant:
1 Using a standard USB cable, connect the device directly to a Mac.
2 On the Mac, open Audio MIDI Setup, found in the Applications > Utilities folder.
3 In Audio MIDI Setup, choose Window > Show MIDI Window.
4 Verify that the MIDI device is detected in the MIDI window.
5 If the device is not detected, click Rescan MIDI.
If the device is detected, it’s class-compliant and will be available to MIDI software.
Windows
MIDI I/O is configured automatically when the Pro Tools | Duet device driver is installed.
Recording Software Settings
Before using the Pro Tools IO Control mixer, it’s necessary to change a few settings in your recording software.
Software Monitoring
Because the signal to be recorded is monitored through the Pro Tools IO Control mixer, the outputs of software tracks actively re-
cording should be muted - after all, that’s the source of the latency. Most software applications provide an option to turn off soft-
ware monitoring of recording tracks.
Playback Mix
In your recording software, set up a mix of all playback tracks and route it to the first pair of outputs. If a master fader controls the
global output of the mix, we suggest setting the fader to 0 dB.
