I/O utility in Logic Pro for iPad
I/O utility lets you use external audio effects units in a similar way to the use of internal effects.
Note: I/O utility is not practical unless you’re 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 effects unit.
To add the I/O utility to your project, choose Utility > I/O utility in a channel strip Audio Effect plug-in menu or the Plug-ins area. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.
I/O utility parameters
Output Volume knob and field: 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 knob and field: Adjust the level of the input signal.
Latency Detection button: 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 Offset knob and field: Displays the value for the detected latency between the selected output and input in samples. You can also use this slider to offset the latency manually.
Dry/Wet knob and field: Set the balance between the direct and effected signal, if effects are used.Format pop-up menu: Choose between Stereo and Mid/Side in stereo instances.
Use an external effects unit with I/O utility
In Logic Pro, connect an output of your audio interface with the input on your effects unit, and connect the output of your effects 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 effects unit, and each connection can be either an output or an output pair.
Tap an Effects slot of an aux channel strip that is being used as a bus send/return, and choose Utility > I/O.
In the I/O utility, choose the Outputs and the Inputs of the audio hardware that your effects unit is connected to.
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.
Adjust the Input Volume and Output Volume knobs as required in the I/O utility.
Tap the Latency Detection button if you want to detect and compensate for any delay between the selected output and input.
When you start playback, the signals of any channel strips routed to the aux channel chosen in step 3 are processed by the external effects unit.
