I recently started using Ableton Live next to Traktor (FS), Vinyls and Buzztracker. The freedom that comes along with this setup is pretty genius. The only thing i miss right now are some Kaosspads II and another set of arms/hands :)
The big thumb down of this setup: It needs too much tablespace for the perfect fun-setup (including 2 oct keyboard and drehbank). Btw, when i started releasing music on the internet in '95 i was dreaming about something like Final Scratch. It's also a good opportunity to play good and fresh music that the public doesn't know. Think about it. Ronny
