So the two issues first:
* My synth did not come with a US power adapter. I have lots so I plugged it in with the one from my old Neutron...
* It did not power up, so I opened it up and saw that the ribbon cable from the daughter board was completely disconnected from the main board. Simple fix and it started up.
So I am not sure whose fault that is but I was glad I could avoid returning it.
Once it was running, my experience was all positive.
The dual filters is a dream come true, especially paired with dual LFO's and dual looping ASRs. I love the multishape LFO/OSC with morphing control. I don't know why the default is to step them, but once that was set up properly, I am getting so many great complex musical sounds. It even has dual VCA's which offers some interesting ideas for a stereo path (VCA2 is normalled to the output of the VCF2 with VCA1 handling a mix. Simply using them as a stereo pair, you can have two different filters in parallel.
Missing are the excellent bucket brigade delay, sample and hold, and overddrive, but the additions allow for a richer set of sounds than the Neutron, (and I still have those features in my OG neutron... along with a stupid amount of eurorack modules).
I consider an instrument worthwhile if playing it helps creativity and performance. My experience in a few days of use is two new songs based on patches I came up while exploring.
tldr; The synth is great. The quality of the unit including power supply and detached daughter board was disappointing and could create real struggle for a novice.
