Expecially the 1 LFO, that's crazy to me. Having said that, i'm not really someone that digs too far into modulation routings and don't really need the capabilities of something like the DSI REV2, I prefer classic synth sounds.
So a whopping two LFO's puts one outside the classic synth sound category? Personally, two is the bare minimum, even for monophonic patches. If a synthesizer cannot offer simultaneous pulse width modulation and vibrato at different rates, then one of the most basic of basic patches is impossible. That's a standard that I find necessary, and it's one of the reasons I didn't care for the Moog Voyager. One of its audio oscillators was constantly being sacrificed to serve as a second LFO. It made one of the Voyager's immense advantages over the old Model D - that of having PWM, rather than several selected pulse widths - only occasionally helpful.
The Prologue does otherwise seem like a decent instrument. I'll be interested to hear its raw sound. I actually have good feelings towards Korg, since I have fond memories of owning two Korg synthesizers when I was very young. But for someone who has an eight-voice Poly Evolver and a Prophet '08/Rev 2, it does seem rather uneventful. I won't expect it to come even close to the glorious sound of my PEK+PER pair.
