The audio inputs & outputs page lets you edit the list of available audio channels.
Sometimes it is useful to either disable a set of channels not needed or to give some channels clearer names.
Renaming Channels
Audio channels in LiveProfessor can have user labels. If no user label is provided the label provided by the audio device will be used. To rename a channel double-click on the channel in the User Label column and type in the name.
Enabling and disabling channels
Some audio devices have sets of channels you don't use. For instance, if you only use the digital ports and none of the analog. You can hide the channels you don't need by clicking on the green check mark next to the channel name.
The audio patch inside LiveProfessor will not show the hidden channels.
Please be aware that if you disable channels after setting up the routing of your chains and plugins, it will affect the audio patch. For example, if you have a plugin with input from channel 2 and you disable channel 1, the plugin will receive audio from channel 3 instead because it has become the second channel in the list.
Virtual I/O
To allow for routing and programming without access to a multi-channel audio device, the ability to add virtual inputs and outputs has been provided.
If a project that was saved with a multi-channel audio device is loaded, and the device is not available the project will enter Offline Mode and virtual I/O will be added to compensate for the missing hardware.
Virtual IO can also be added and removed manually using the Add Virtual, Remove VirtuAL, and Clear Virtual buttons.
Virtual IO will always be pushed to the end of the list, with physical IO taking priority.
