How about using the Scarlett as it is, but feed the mixer's aux out or record out to the Scarlett ?

By the way thank you for your feedback.

I have the Mackie Pro FX12. same thing minus the 4 extra channels.
the Traction software that's bundled with the board when you purchase it suggests using ASIO4ALL.
this will cure your latency issues. but I honestly believe the Scarlett has better pre amps in it than the Mackie Does.
I have a Focusrite 18I8 and that's what I use as a full time AI. I got the Mackie to use for micing up a drum kit, monitoring, exc. IMO the USB is a bonus, so I can hear an IPOD, or send a stereo mix to my laptop.
but one thing is for sure, the Mackie Pre amps cant touch the Focusrites Mic Pres, even on the cheap little Scarlett's.
because the mic pres you have in your Scarlett is the same Mic pres in the larger Focusrite units (except the ISA and Claret) its just you only have 2 mic pres on the 212. The big units have 8. my 18I8 has 4 but I also have 4 more 1/4 inputs, lightpipe and SPIF.
This is how I convert 8 track tape to digital (I do a lot of conversion work)
 
Its all about mic pres my friend. Ask any good engineer.. They will tell you,
Even though I own one, a Mackie's Mic Pres is not better than a Scarlett. The noise floor is also not even close.

Thanks bro, I think I'm going to take your advice go back to the Scarlett as my input, but I think I can leave the Mackie side by side to use as my output still on the USB right? If not I can always go to the outs from the Scarlet to the mixer but with my other mixers always found that a little bit unsatisfying... either way I appreciate very much somebody confirming what I had already suspected but was not going to be able to decide without a push, and then maybe I'll find a larger Scarlett and trade up the 2i2 was one of my very first purchases not really knowing what I needed for Studio...
Thanks again

you can use your Mackie to to send the signal to the Focusrite if that's what you mean,
but be sure to Tap the insert. its a cleaner route to your Focusrite.
using them side by side might be impossible (Using 2 USB devices at the same time)
it will cause driver conflicts, though some might have a better idea on that.
 
your Scarlet will use an Asio compliant driver, while the Mackie will use ASIO4ALL.
that's a recipe for destruction. however, you might be able to try WASAPI.
a user here on the forums swears by it and I trust his judgment. so possibly another option.
