I cant decide whether to buy the XP30 or the JX305. I make experimental music and want to make the wierdest soundest possible, lots of them. Is the XP30 as "synth-like" in that respect? I like the sounds synths get when you get extreme with the cutoff and resonance. Will the XP30 allow me to get that extreme? Can it do everything the JX305 can and more? IF so, is it worth 300-400$ more? I don't make typical dance/techno music, but I love electronic sounds. Will the not regret buying the XP30?
