Re: USB Audio Interface?
I don’t know much about Emu’s audio interfaces, just know they make some cool keyboard sound modules back in the day.
I’ve had or used these two interfaces
then of course I have the 8 channel version of this:
The M-Audio Mobile Pre was my first interface and did well. The firewire one we got for church to use and did well.
The Native Instrument one sounds great, fact I use it to record my mixes and did a sound job this past week.
Also, since you’re considering to learn Pro Tools, you could pick up one of the small MBox interfaces as well.
Any of these choices are fine for just recording a stereo track.
