Often I will play karaoke videos from Youtube to sing along with. Is Presonus going to allow me to listen and record that music at the same time I'm recording my vocal on a separate track by itself without picking up the music from the video playing?
It will - as much as any interface is going to; you're going to have some issues with all of them if you attempt this, regardless of who makes it or how much you pay. You are going to have to be careful how you monitor yourself and the video, otherwise the replaying video will break through - you don't want it through speakers. So you are going to have to wear headphones, and keep the level down. And I reckon that initially, you may have a bit of fun with the configuration. Playing a track back from Audition whilst recording your vocals is easy - that's bread and butter stuff. The problem is going to be getting a live video feed in, and recording yourself at the same time.
To me, the most obvious solution is to get your video into a form that Audition can play, and play it from Audition whilst recording yourself - then you won't have any problems at all. There may be other solutions, but they are going to take a bit of thinking about. The problem is that you need the external video to play its audio to somewhere, and you to be able to hear the results somehow, and using an external device with Audition rather precludes this - Audition uses an ASIO engine, and it cannot (because of Steinberg's specification) run with more than a single sound device, although you can get around that somewhat with ASIO4ALL - possibly...
Your real problem is going to be getting an output from whatever's playing Youtube and Audition at the same time. Essentially you need an internal feed going to one Audition channel - people have a lot of trouble doing this anyway - and on top of that, you need to be able to record yourself using another device and also feeding the Youtube output to your ears, all together. That's a routing nightmare in a PC! Another way to do this (and it would also work fine) is to use another PC to play the video, and this is probably going to be a much better bet - far more controllable. There's only one slight snag though, and that's that you'd need the next Presonus up, as that's the one with the line inputs you'd need for recording the second PC.
