First I had the rack version (CS6R), but with a strange business, I replaced it to the full workstation. So when I first began to make a new preset, I just gone empirical, menu-by-menu, feature-by-feature. And it all amazed me. The ROM sounds are incredible good selection for electronic styles. Really, tell me another synth which has at least so focused and even reach samplepack in it's heart! I can't, because CS6X is truly one of the best EDM synth ever built. That filters! You get many characteristics, in "analog" and "digital" type (the "A" in the filter's name means "analog", while "D" means the "digital" version), and it seems all can scream but "A"-types are more. From raw bass sounds to thin belly tones you can find everything, but don't try the drum sounds, you will be disappointed. Otherwise, arpeggiator is far enough to fire typical house, trance or acid phrases, and best of all, it has something similar to MOTIF pattern audition, so you can bind a style-pattern to a preset. Effects are good and all can make serious changes in the sound. I feel myself a bit stucked with 2 MFX channel + 1 master FX for the whole bunch - but another hand, performance mode has the ability to act like a perfomance mixer console, so you have a 2 band EQ, Chorus, Reverb and MFX send on all the 16 channel, and the summed signal could be processed by the Master FX. After all, this is a rompler, but the good wavetable, the tasty and crazy filters makes this instruments a real well-developed gear ready to make your hits in effectively short period.
