My current setup is a Delta 1010 and I use an Alesis Studio 24 mixer, mainly for things like routing.

Of course the n12 does what both the 1010 and the Studio 24 does as well as seperate mic pres.

I don't see that the N12 has an Aux Input. On my console I use an Aux Input for mixing.
There is aux in from the DAW and there is 2 track in for monitoring.

How would I do this with the N12? My thinking is you would set it to ST mode?

Actually ST Mode is 12 Analog inputs that go to the Aux bus for talent monitoring through the Aux Phones, the Stereo bus along with the 2 Track input sent to the main outs (Also sent to the DAW) and the Rec Bus sent to the DAW.

The Hardware Mix Mode is 12 DAW inputs + 2Track Input DAW Aux send + DAW Stereo Send for monitoring, Of course you can then bounce all of that to the Rec bus back to the DAW for Bounce Downs recording using the EQ Compression and Rev X Reverb

The routing can be very powerful but not needed for day to day recording..

If you have more detailed questions, send me a PM
