I tried MixMeister couple years ago,but found it very boring
I use sometimes Ableton for mixing accapellas and tracks for further mixing, also tried Virtual DJ which is stable but its so far the worst mixing software ever,lol...using Traktor for about 5-6 years now and its really the best and easiest for me to use
I got a Creative sound card (internal) so I can mix in Traktor with an external mixer.
If you need any help with Traktor just let me know,but it would be better if we would contact via msn or skype.
Must mention that my fave mixing is on Technics turntables
