Will an audio interface improve play back sound quality?
Over the winter I bought a Focusrite Scarlett 2i2 USB audio interface for the purpose of hooking my acoustic guitars up to my comps, which I haven't bothered to do yet. But most of what I do with music on the comp is just with VST's in daw's and sometimes plugged in to notation software like Overture. I rarely record any audio and don't plan on ever recording much audio. I kinda like keeping my acoustic universe separate from my electronic universe. I've been happily using my on board sound card exclusively for a long time. If I'm only using VST's on a project would the Focusrite improve playback quality through my speakers and/or render quality when generating mp3's compared to what I get using my on-board sound card? I know this is really basic, but, frankly, I don't know if the sole purpose of this device is to connect physical instruments, or, if it also improves these other things. Thanks in advance for any guidance.
