When you have chosen the Saffire as the audio interface within the audio recording software (ie your sequencer), the input and output options audio that is available will relate to those within SaffireControl. For example, the user can select inputs 1 to 4 to be recorded to an audio track, which will relate to inputs 1-4 in SaffireControl, and similarly will be able to select outputs 1-10, which will become S/W tracks 1-10 in SaffireControl.
