Hi, this is my second post, and I'm still in the overwhelmed stage. Many things I could ask, but as I consider how to record audio onto my pc laptop-never have done before- I have a Samson condenser mic with an XLR end that obviously won't fit into my little 1/8" input on the side of my computer, so I assume I will have to shell out a couple hundred or so for a decent interface? Also have a keyboard and acoustic guitar to add in for a possible adding a few notes.

second question, not sure once I get all this how to adjust the volume of the input.
