yes indeed the JP8000 super saw can give you that Ferry Corsten sound. As roland says, that super saw is seven sawtooths simultaneously, all detuned slightly +/- to make it a little thick. This sound on the JP8000 is a little thin and with the treble knob right there on the board (or rack in the case of 8080) you just crank up the treble a bit and you're close to that sound. Also the JP's have that cute delay knob right on there so crank in a little tempo dependant delay, find a good riff, and you're cruisin'
With that said I've owned both the JP8000 and JP8080 but I've sold both since. This Ferry Corsten sound we're talking about is the one thing I miss about my JP - other than that it's a bear to use, not to mention set up in your midi rig...I've got the Nova and the CS6x now, and I can still coax that sound out of them by layering sawtooths, detuing them by small amounts, and adding the proper treble and delays..
