Have unboxed, and set up, messed about for about an hour, and no recordings for now.
The major points:
1. It sounds amazing and is so malleable that when it does not, you can make it so.
2. Annoying when you switch presents with delay/verb still hanging on. This needs a bug fix, but for the time being, don't do that.
3. Fan noise after the initial boot up is not bad for me. Quieter than a computer, a Deepmind, or background noise of a guitar amp turned up loud.
4. Gain staging is supremely important, in a good way.
5. Took one of my go to OB6 patches, just because it happened to be sitting within arms length, and tried, with limited success, to match it. Suddenly got much closer when I played with the envelope attach curve. This is potent. Ultimately found a Moog preset with OB in the name that was in the same ballpark, tweaked that, and got a little closer. Still, that particular OB6 patch makes my big toe shoot up in my boot, to quote Little Richard.
6. The oscillators definitely do not, without assistance, jump out of the speakers crackling with life like those of a Model D or some vintage VCO's. They are however, to put it in a good light, classy and rich. Also versatile, and with the waveform shaping and mixing, capable of a huge variety of tones. They are more lively with no modulation tricks than say, the digital oscillators of a Pro-2, or the DCO's of a Juno ( or DM12 as a contemporary example). One of my next moves will be to use a boost pedal with a little bit of "hair" on it on an insert with the filter wide open, and bring it into the external input of another "synth" to drive the filter a bit more, and to see how Minimoogy it can get. I will also similarly experiment with using my Voyager oscillators with the slew rate mod triggered via midi into an external input mostly for my own edification as an A/B. Will do same with the OB6 or Prophet 6.
In a short time, what I know it can do is to be an absolutely brilliant and deep polysynth. In my mind it is the love child of a Pro-2 and a Voyager, but with both of their best features, and better looking and more successful than its parents. I did most of my little bit of tweaking sans effects, but I'd pop them on to mess with them, and they are wonderful. It can cover a lot of ground. A string sound with the ensemble effect sounds pretty great. A fat but clean bass - pretty great. Pillowy OB type sound - great. Still working on a screaming lead where one note will raise the hairs on your arms. Think I can get there. But where this will really shine is not covering for other instruments but exploring what is uniquely the Moog One, and that is by far the most exciting thing.
