I love the old Oberheim sounds and continue to enjoy trying to get them on these analog synthesizers. The '08 and Rev2 do indeed achieve some great Oberheim patches. There is a Jump patch on the Rev2 (Jump!), and the GEOSynths patch set for the Rev2 has one too.
Although the Rev2 Jump patch is a great sounding Oberheim patch (I like what they do with the additional slop setting on that one, which wasn't possible on the '08), I think the original patch from the Prophet '08 (Yump) is still the most accurate of the three. It's pretty simple: no resonance, oscillators at -5 and +5, etc. That patch has a slight pitch blip/ramp up at the attack, which the designer must have heard. I once slowed down the recording of Jump to hear if there was a slight ramping up or down of the pitch. I didn't hear one, but I did hear a very short/fast tremolo on the attack, which isn't noticeable when played at the normal speed. So I eliminated the pitch blip and instead use the third EG to get a very short and fast tremolo... and then dial it back to an appropriately subtle level. Putting this sound into the Rev2 means that you can also program in some delay, which helps a lot. Like everything else, these patches sound much better when using Sacred Synthesis' stereo arrangement, such as with an '08 module. Everything else makes subtle differences, but running it in true stereo from two different units really gives it the 'wow' effect.
