That's my opinion, too. All things considered, the Prophet 12 is the best hybrid instrument that someone of my financial circumstances could possibly afford. And that's not a complaint, because there's more in a P12 than I'll ever need. But I personally wouldn't want a synthesizer that approaches the price of a car or a down payment on a house. It's just too much invested in one object. I'd be afraid to turn it on and use it, lest I break it!
The funny thing is - considering the theme of this thread - the P12 now lingers in my memory as more of a virtual analog than a hybrid or digital synthesizer. I spent little time experimenting with its digital prowess, except for running through its few digital wave shapes. Coming from the Evolver's 90+ digital wave shapes, plus its several analog, they certainly didn't impress me, but I realize it's a matter of what you do with them across the entire instrument. The oscillator is such a fundamental component in synthesis; and yet, with the P12, for the first time I felt as if it was only the bare beginning of a long series of events, at the end of which the oscillator would hardly seem to be of importance. I realize that's technically incorrect, but I'm describing an impression the instrument left.
So, until I've had my hands on one again, it's hard for me to consider the P12 a "digital synth". The instrument just doesn't fit into a category I can name. It's more of a nondescript masterpiece, if that isn't a contradiction in terms.
