RME Fireface 800 techniques

I use fireface interface and I find this one to be really cool.
Sound quality is superb.

what's interesting is their software mixer. I know lot of people dislikes software-ness but there are more advantages than disadvantages.

first you have presets. and You can toggle presets 1-8 by doing Option + preset number (probably alt + # on PC)
I have so far 3 types that I use
1. Listening/Monitoring - one with good volume setting for whatever you want to do
2. mute monitor for Recording purpose
3. one for listening back direct signal (yes you can do this if you turn up those faders for mixers.)

secondly MIDI control
you can use your motorized controller, or midi keyboard, etc to control faders.. even when the software is in the background...
it doesn't have monitor fader on the outside but you can actually add them. and for all of them. every single inputs can have different monitoring levels. (like when you don't need much of anything other than kick and snare in the headphone mic.

submixes..
you can create submixes.... it works like a mixer.

Very cool. good in studio and works amazingly LIVE
