Use I/O utility
I/O utility enables you to use external audio eects units, similar to using internal eects.
Note: I/O utility is not practical unless you are using an audio interface that provides discrete
inputs and outputs, either analog or digital, that are used to send signals to and from the
external audio eects unit.
I/O utility parameters
•
Output Volume eld and slider: Drag to adjust the level of the output signal.
•
Output pop-up menu: Choose the output, or output pair, of your audio hardware.
•
Input pop-up menu: Choose the input, or input pair, of your audio hardware.
Note: The Input pop-up menu is visible only when an audio interface with multiple inputs
is active.
•
Input Volume eld and slider: Drag to adjust the level of the input signal.
•
Latency Detection (Ping) button: Click to detect the delay between the selected output and
input. Following detection, any delay is automatically compensated for.
Note: You can obtain the most accurate reading by bypassing any latency-inducing plug-ins
on the track.
•
Latency Oset eld and slider: Displays the value for the detected latency between the selected
output and input in samples. You can also use this slider to oset the latency manually.
Use an external eects unit with I/O utility
1 Connect an output of your audio interface with the input on your eects unit, and connect the
output of your eects unit with an input on your audio interface.
Note: These can be either analog or digital connections, depending on the features of your
audio interface and eects unit, and each connection can be either an output or an output pair.
2 Click an Insert slot of an aux channel strip that is being used as a bus send/return, and choose
Utility > I/O.
3 In the I/O utility window, choose the Outputs and the Inputs of the audio hardware that your
eects unit is connected to.
4 Route the signals of any channel strips that you want to process to the bus (aux channel strip)
chosen in step 3, and set appropriate Send levels.
