SaffireControl has two buttons on the bottom right that are used to select the two main modes of operation (TRACK MODE and S/CARD MODE: the first is the standard tracking mode for recording (the default mode when SaffireControl opens) and the second is for mixdown (Soundcard mode) when you want analogue outputs 1-8 on the rear of Saffire to match outputs 1-8 within your sequencer. The comprehensive monitoring capabilities of the Saffire means that, without preset buttons, numerous settings would need adjusting on SaffireControl to simply route 8 tracks from your sequencer to the relevant outputs on the Saffire (Soundcard mode). This is because, simply selecting a stereo drum track to be outputs 3/4 on the mixer in your sequencer will not route that track straight out analogue outputs 3 and 4 of the Saffire hardware but instead into S/W tracks 3/4 within SaffireControl. This is so that, in tracking mode, those tracks can be mixed with the audio being recorded to make monitor mixes for artists. Focusrite's clever design team have taken all this into account and included a button to route the outputs set as 1-8 within your sequencer straight to Saffire's analogue outputs - this is listed on the Getting Started A4 sheet that comes in the box and also explained as being a good way of getting to grips with the workings of SaffireControl.
