Just tested and bought this yesterday.
As I'm invested in the Arturia ecosystem + this sounds good and was instantly inspired - this was more or less a no brainer for 49.
+ Arpeggiator -> I love synth integrated Arps as they often are more tuned for the envelopes of the synth and this one can be modulated and has some good options
+ Pan/Spread tuning, good feature, although nothing new as this was possible with modulation eg. in Diva. Quite nice is the visualization though
+ MSEGs/Functions -> Sound Designer love this
+ it's really easy to use. Arturia have a big advantage here with their framework
+ Effects are quite good
+ Synth sounds "fat" and has low end (often missed with earlier vintage emus)
-+ Although I didn't go to the extremes of the filter which is often critized with Arturia, but I could instantly make a track and had a fat lead and bass sound (unlike with Pigments, which is more suited for Pads, Strings etc.)
+ Resizable interface
+ Undo history
+ GUI is really good, I don't mind the OBXa lines
- effects should be re-arrangeable. Currently you need to decide the order before tweaking, as they can't be moved/copied aftewards
minor request: effects should have presets
