Fostex MR-8
 

Hi,
I have Fostex MR-8. I wanted to record and mix with it. I used 4track and thought that I was ready to mix and used USB system through my computer. The song end up each track was recorded to separate files. How can I mix it in one file? Do I need a special software or CD recorder to do mixing?
What I did was that I recorded my guitar and vocal used only 4 tracks, and connected with USB cable direct to my computer. I do not have anything more than MR-8 and computer. My computer is Acer aspire 5742. Thanks in advance.
