Well, at 44.1K I have to wonder what market they're aiming it at, cause it's generally accepted since as far back as I can remember, that 48K is the sweet spot beyond which you get diminishing returns. I've always been in agreement with it too, cause I've obseved it first-hand.
For a product such as this, 48K should have been the absolute minimum, after all, the job of the sampling on this device is to capture the "analogue" aspect as faithfully as possible. 44.1 is indeed very capable, but I happen to know first-hand that 48K is notably better at it. The sampling should have been left to the DAW, that way the device would only ever have been limited to the processing power of the computer running it.
Regards the VCO/DCO thing, personally, as long as the oscillators themselves are true analogue then I'm not too bothered about that. I love the Roland JX-8P, intend to own one some day, and that's a completely digitally controlled analogue.
So in a nutshell, for me, a synthesizer can only truly be said to be analogue if it's signal path is 100% analogue. And the unfortunate thing is, this device falls flat on it's back even if that were the case internally, because there's no way to get an analogue signal out of it without going through conversion.
It's like they're saying, here's an analogue synth, but sorry, it doesn't actually output analogue
So my own personal conclusion: I think it's a good overall idea that was poorly thought out.
