Say two for the piano and > the > third for the voice...? You described connecting the mixer to your computer's line-in port. The line-in is stereo ie 2 channels. So, yes, you can connect more than 2 mics to a mixer, but then use the mixer to mix/merge those signals into just two which you send to the computer. It mean the decisions on how to do that mix have to be made at the time of the recording... which is not easy if there's background noise, or hardly any time to do it, or you are listening on headphones whereas later on you could also listen on speakers... A multi-channel USB audio interface lets you record all the signals at the time, then do the mixing and experiments later. -- Jeremy Nicoll - my opinions are my own.
