I know I'm going out on a limb here, but for what it's worth...
While I would not make any pretense of having a clue as to how an analog synthesizer performs its magic, much less knowing how that magic is emulated in software, much less knowing where an emulation falls short of the real thing, I can't help but feeling that getting on Arturia's case over the shortcomings of the MMV relative to an actual Moog Modular really isn't going to accomplish much of anything regardless of the merits of the case.
I didn't plunk down my hard-earned cash for the MMV with any allusions as to its ability to replicate in software with immaculate accuracy a piece of hardware that costs 50 times as much as what I paid for the software. I bought the MMV because I liked the sound of the software when I played with the demo and thought it would be a good addition to the my arsenal of soft synths. I didn't buy it because I expected the emulation to be flawless in every respect. The mere fact that it is billed as an emulation, in itself, is a case of truth-in-advertising.
I use a number of different soft synths in my music making and I find that while each one has it's advantages and drawbacks, in general my ability to turn the sounds I hear in my head into reproducible audio, as well as to stumble on new sounds as I experiment with each soft synth's capabilities, results in recordings that meet my exacting standards to a much greater degree, and at greatly reduced cost, than if I were to amass the kind of hardware arsenal associated with outfits like Tangerine Dream, Klaus Schulze or any other well known electronic music artist with gobs of money to spend on acquiring and maintaining every electronic gizmo in existence.
And I've got more news for you: the MMV is not the only example of "sloppy programming" in existence as far as synth emulations go. I'm not going to name names, but I've run into problems of some sort, both large and small, with virtually every soft synth I've ever worked with. In my view, it's the nature of the beast. If you're going to cut corners and use a piece of software to replicate the functionality of a hardware equivalent costing many times more than the emulation, you've got to figure corners are going to be cut. You're a fool if you think otherwise.
So yeah, while there are many holes in the MMV and a case can indeed be made that Arturia has dropped the ball as far as getting them plugged is concerned, in the final analysis it meets my needs and that's all I care about. I have no allusions of living in an ideal world as far as music software is concerned - I'm just glad I can do the kinds of things with it I could only dream of doing back when hardware synths and recording studio gear was the only option.
