Emax

I had a K2500RS and I didn't like it. I could see why people did but no my kind of texture. Too complex, too many perameters, too many options that no one actually used. If you were an actual programmer kind of person the machine is awesome. But for me was anoying and everyone who had it barely pulled something different out of the presets already had. 

Personally I like the Emax II beter even is an inferior machine but is simple and to the point. For me is more fun to use, is more towards live performance and music rather than programing.
