quick question- is this for mixing live or doing post production editing/ mixing
for post production editing I use Audacity- it is a free Open Source program that works as well as programs like Adobe Audition or garage band.

Its a free software you can download & become your own DJ mixing & what not.
hope this is what you were looking for.

that should take you to the right place & it offers you a free download.
