Hello, I'm from Brazil and like every undergrounds dance styles... I buy a JX305 and love it. It had 768 patterns from de garage to the jungle... and the sounds are not too clean. Had a set of 3 effects, a reverb, a delay and a multi effect with over 30 effects, including the vinyl noise.

I don't know the yamaha's cs1 or 2 but my friend had both the jx305 and the cs2 and he prefered the jx305.

ops, it had a drum machine and a 8 track sequencer built-in, with also simulates the up and down the speed of an vinyl...

exculse me for my bad english...

I hope help you.
