It's supposed to be a premium pack of vintage analog synthesizer sounds but those sounds showcased fall seriously short. Yamaha has never had great samples of analog synthesizers and other than the CS-80, Yamaha has no analog synthesizers to speak of worth a damn.

I definitely don't see Ian ditching his Jupiter 8 for the vintage synth pack. The Tyros 4 is a decent keyboard but in no way are its synthesis capabilities on par with the best analog synthesizers of the past. To think otherwise would be foolish.
