Hahahaha I actually really want to make a skat track.
I use FL Studio, 9 to be exact.
I have legally owned it since 6 was the latest version, so I have 10 through 12 and use them from time to time for some of their plugins that don't work in 9.
However they changed the interface and a few features in 10 and I just feel most comfortable in 9 so I still use it 99% of the time.
How about you?
