Setting up my room for digital mixing (I've been in the analog world way too long!). I understand an external audio interface is better than using of the onboard connections on my laptop. Can anyone recommend a reasonably priced external audio interface? Looks like the prices run the gamit but I really only need it for stereo in and out, possibly a MIDI interface. TIA. I know this is pretty basic question but I appreciate the wealth of experience out there.
