Yeah. I was hoping to minimize additional hardware (and clutter)... trying to use the built-in (crappy) sound card in my laptop... trying to do things mostly in software. My laptop only has USB 1.x so the Audigy (USB 2.0,) while I'm sure is a good value, would not be optimal. If I were to get an external sound card, I'd probably look into an Echo, Terratec, DigiDesign or something like that (I'll need to do MUCH more research) and make use of a PCMCIA device.
Oh, now I've tried the Amplitude. I agree with tsl602000. It is a mess (bad user interface design) to get a good sound from it. And I couldn't try the Warp VST because Steinberg doesn't have it (or any of it's products) available for download. Well, I'm ok with the ReValver for now... I still say it sounds pretty good and the UI is easy .
