I/O
The I/O plug-in allows you to use external audio effect units in a similar way to using
the internal Logic Express effects. This only makes sense if you are using an audio
interface which provides discrete inputs and outputs (analog or digital), used to send
signals to and from the external audio effect unit.
I/O Parameters
 Output Volume field and slider: Adjusts the volume of the output signal.
 Output menu: Assigns the respective output (or output pair) of your audio hardware
to the plug-in.
 Input menu: Assigns the respective input (or input pair) of your audio hardware to
the plug-in
 Input Volume field and slider: Adjusts the volume of the input signal.
Using the I/O Plug-in
The following section outlines the steps you should follow to integrate external audio
effects in the Logic Express signal path.
To integrate and use an external effects unit in Logic Express:
1 Connect an output (or output pair) of your audio interface with the input (pair) on your
effects unit.
2 Connect the output (or output pair) of your effects unit with an input (pair) on your
audio interface.
Note: These can be either analog or digital connections if your audio interface and
effects unit are equipped with either, or both.
3 Click an Insert slot of the channel you want to process with the external effects unit,
and choose Utility > I/O.
4 In the I/O plug-in window, choose both the Output and Input (shown as numbers) that
your effects unit is connected to.
5 Adjust the Input or Output volume as required.
When you start playback, the signal of the audio channel will be processed by the
external effects unit.
