[sdiy] Reproducing Oberhiem "Jump" Voice

[Richard Johnson]

Dear List,

I'd like your input on reproducing something similar to the Van Halen
"Jump" voice. Some research yields:
It is a "brass" voice was produced using a Oberheim OB-Xa. (Sorry if
this next part is pedantic. I'm new at this.)

Oberheim OB-Xa Specs
   8 voices
   Technology: PWM Synch
   2 OSCs (Waves: pulse saw noise)
   1 Filter: LPF Resonance 2-4 Pole
   1 LFOs: sine, square, sample+hold
   2 ENVs 2x ADSR

My goal is to implement a similar sounding voice with very few
components (some may be digital). I don't have an analog synth to use,
so I've been using software synths. Any help would be appreciated.

Another list member suggested that it looked like a combination of a
Sawtooth Fundamental + a Pulse Wave at 5F or 10F in sync.

I don't think ENV or LFO are too big of a concern right now. The LPF/Q
might be though. I've come up with something close using Sawtooth (F)
and a pulse (2F) on a software emulator.

Can anyone confirm or deny? Also is there some sort of standardized
notation for building analog voices like there is for FM voices or do
analog synths vary too much from one to the next?

Thanks!
Ric

P.S. Sorry to ask for the cliche of all synth sounds. Please no tar,
feathers or Mangus Chord Organs.
