I have very limited experience with home recording - mostly very crude efforts using Audacity and an analog mixing board into the PC sound card. I am interested in doing more recording for my own amusement; capturing ideas, creating backing tracks to improvise with, etc. Ease of use would be my priority, with versatility second. I thought that a small mixer with USB output would be a start. I searched other posts in this forum and saw recommendations to use an audio interface instead. I am trying to decide which would be best for me. A small mixer could do double duty for live gigs. I looked at a Line 6 audio interface that comes with modeling software for classic amps and stomp boxes. What things should I take into consideration before jumping in?
