How can I reproduce this patch on a Voyager?
The Rogue patch seems trivial to set up on the Voyager, but nevertheless I am struggling with setting this up.
Apparently I am unsure about the interaction of the modulation LFO VCF On, OSC 1 Contured, Contour Generator Sustain In, Contour Generator VCA bypass and the Mod Wheel.
There seem to be things under the hood that are not easily affiliated without a block diagram.
Any help is greatly appreciated.
Thanks,

You may not be able to replicate it. The dealbreaker is hard sync. The Voyager hard sync is nowhere near as nasty sounding as the Rogue.
Ok, hard sync or general sound texure aside, focusing on the modulation routing, can I somehow get the same behaviour of the Rogues Modulation to Contour Generator VCA mode?
I had a hunch and just found the MG-1 block diagram:
Is this comparable to the Rogue functionality?
Aside from the obvious missing polyphony on the Rogue, there are also other differences:
The two oscillators share a single toggle switch for waveforms on the Rogue, as well as octave choices. Whereas the MG-1 has independent control for each.
Also, the MG-1 has separate sliders for modulation levels individually sent to filter cutoff and pitch. The Rogue uses the single mod wheel as levels for both, and you can only switch on or off the modulation.
The Rogue offers envelope modulated sync, however, and the MG-1 only offers the sync on or off, with manual control of the slave oscillator.
That’s why those two models are more like cousins then brothers.
As for your patch on the Rogue, from what I see, there’s nothing there that the Voyager can’t do.
Great, will try again with your comments in mind and report back.
Thanks!
Auto trigger is missing, so I guess this isn’t possible to recreate on a Voyager. 
Opening another thread for this.
From the Rogue manual:
“Auto Trigger will trigger the contour generator at each complete cycle of the LFO, when turned “on”.”
Yep. I had missed the auto-triggering part of the patch… 
But looking at it more closely, having an LFO at medium-fast speed, auto-triggering an envelope with relatively slow attack setting, and short decay, that controls both the filter cutoff and the VCA with osc1 and 2 levels very low in the mix, would not produce a very audible patch ? This would likely sound like a somewhat distant, quasi pulsating, randomly pitched both by the oscillators and the filter, with lots of white noise, patch. In other words, a sound effect. And not a very loud one.
Anyway, sorry to have missled you. I thought it would be feasible on a Voyager. I’ve even thought of using an ramp-up waveform from the LFO to simulate auto-triggering of the envelope contour on the filter cutoff and the pitch, but alas the Voyager doesn’t offer such a waveform for the LFO.
The Rogues VCA is bypassed (i.e. always on) in my picture. Would that change your visualization of the patch?
Still working on getting a similar sound on the voyager. Main hindrance so far were a non cycling envelope (solved by setting Filter ENV Trigger: S+H and Env Gate: ON/External) and a non ‘all the time’ open VCA (solved). To be solved: the Rogues Contoured sync behaviour and still working on getting the unexpected, irregular and organic opening and closing of the Rogues envelope. Trying the VX-351 Smooth S+H out to ENV Rate input next.
