You don’t buy a Model D for modulation you buy one for the sound it produces. 
Once again, is it possible to apply the Voyager in a modular capacity through some sort of “virtual patching” system, like the Oberheim Matrix 6?
Quote by Cruel Hoax:
I think people waste too much time worrying about whether or not the Voyager sounds like a Model D.
Totally agree. I think people worry to much about having the EXACT same sound they hear on a cover tune, or a classic rock song. If you play in a classic rock band, sure, you want to get something close, but I won’t spend hours upon hours programming something that doesn’t really need to be indentical in the first place.

True. But I have been thinking about this a lot recently so I spent the weekend gathering model d samples from various sources. It’s been years since I actually heard one and I wanted to differentiate between the actual sound of a d and the sound I have been referencing on recordings (and whihc were the source of my initial disappointment with the voyager).
And you know what? I could pretty much replicate all of the samples with the voyager. There were the occasional differences: the d does punch more (but I could get around this by bringing my modular into the picture - it’s definitely the voyager’s envelope shape that is largely to blame here), and it definitely has a bit more high end and drift, but the vast majority of d sounds were well within the voyager’s range. And, in fact, I generally preferred the tightness of the voyager to the d’s width: the sounds seem to sit better whereas with the d I’d definitely be reaching for eq and/or compression. I also realised that I am not terribly interested in the stock moog sounds anymore - the vast majority of the presets I have created on the voyager don’t sound like a d at all
