The analog sound-generating hardware in both P08 and REV2 is identical*. The only difference is that REV2's software exposes functions of PA397 chips unused in P08 (PWM for all waveforms being one example - which is there in P08's hardware, but sadly was ignored in the original).

*a sidenote that was always interesting to me - REV2 comes with a suboscillator - but it's not a part of PA397 spec - which probably means it's digital since there's zero circuitry for it on the voice boards?

I’ve owned the OG 08, MoPho, Evolver, Tempest, Tetra(2x), 12 and REV2, and while there wasn’t overlap between the 08 and the REV2, or even the Tetras and the REV2, but I’d swear there’s something a bit more polished sounding in the REV2. I thought at first it was just the effects, but even with a patch I’ve made myself from an initialized patch, it just seems like a sweeter sound.

I always assumed it's just the sound of the curtis chip used. Does the rev.2 improve the sound, or take away from some of the character?
