First Microstudio is not for running shows, but for working with your files, creating custom CDs, and a bunch of other things.
Hoster is for running shows and the recording capability has not been included yet, though it is on the list of functions to be added.
Additionally, just so you understand that for your recording to be legal, you can only record them if they own the CD/song that is being recorded. They can not be singing from one of your CDs and have you record it. It is pretty complicated but there are other threads that go into this.

With all that said, to record on the computer you will need an unamplified output from the mixer to the line-in or microphone input on your sound card. You will need to figure out what type of connectors you need for the mixer and the sound card to get the right cable. This varys from equipment to equipment, so no way for us to tell you exactly what to get.
