It's very different than Diva. Diva is a kind of Swiss Army Knife of synthesizers, and with that you get a lot of flexibility and added features, like polyphony, but at the expense of sound quality when doing audio rate modulation. Both are great for different tasks.
You are wrong my friend. "ADS" does not mean that there is no "Release" but that it is hidden, that is, the "Decay" pot controls the "Release" stage as well. In a real Minimoog you use one hand to play the keyboard while with the other one you move a single pot that controls "Decay" and "Release" at the same time: there is no way to do that using this plugin. If you use a real Minimoog you will quickly realize the great difference that exists when modifying the envelopes while playing the instrument.
Definitely not a deal breaker for me. For the price and no need to do maintenance, etc. I'm perfectly happy with Synapse's offering. And yes...why not just MIDI assign those 2 parameters to a single CC knob?
