Boss Gt-10 To Audio Interface?

Hi all,

I've been trying to understand the basics of recording by reading up on all of the forums, articles, etc. But can you believe, I still have questions?


I'm looking into buying a USB Audio interface. One of the purposes is to use a mic for acoustic parts, and possibly vocals. That's pretty clear and understandable as far as preamp functionality is concerned.

- However, as for the Boss GT-10... Is there any advantage of connecting the output from the Gt-10 to an audio interface as opposed to just directly connecting the Boss GT-10 via USB to the computer? And if so, what output would have the best results (digital out, headphone out, vs. Stereo L/R 1/4" outputs?
- Apparently some folks have connected their GT-8s to an audio interface. But my understanding is the the Boss GT-8/GT-10 functions as an audio interface itself. I would think that you would want all of the processing to be done on the GT-10


Anyhow, I'm looking at getting the Roland UA-25EX Audio Interface (To used with a Windows 7 system)

Roland UA-25EX

For the 1/4" and XLR inputs, however it appears only one (the Right input) has Hi-Z/High Impedance feature on the UA-25EX. So that would rule out stereo output from the GT-10 right? Other audio interface suggestions are welcome.

THANKS!!!!
