FWIW, Now you've already bought one.. I have an AN1x and LOVE it. (I've also got two analog JX's from the 80s, DX7II, D50 etc)... so I've always had 'convoluted' interfaces on my synths... so the AN1x feels VERY nice in comparison to lots of menus... sure the control matrix is a tad fiddly but most of the actual 'sound' editing is done from the knobs/bank buttons and I find them nice to use
In fact I've just come back on here after taking my synth to my bed for 2 hours and just sat with it programming 10 new sounds for future work.. Great (smooth) leads, some atmospheric pads (that give my D-50 a run for it's money, not quite as warm but more spacey/epic/evolving), and some sfx...
As a controller the keyboard has a great feel (for fast synth playing) - it's a 'cheap' one by Yamaha's standards but it's a quiet action which I like and the keys just feel smooth and compliment the sounds I make well..
I dumped all the trance style sounds when I got it as that's not my bag and now it sounds like a virtual prophet 5 meets Minimoog meets CS80 meets Jupiter 8... ok not as hot as any of them, but a nice enough aproximation in a mix and lots of extra toys too
I use the editor, the soundquest one I've tried too and both are good - actually the sound quest one is more ergonomic (bigger windows for sequences etc IIRC).
But nothing beats just sitting with it, hands on , using the 8 (x8) knobs (yes it's very easy to just hit a button for VCO/VCF/VCA etc - not like you need ALL of them to hand at once) and tweaking the sounds to perfection. It's my most 'fun' synth for sure....
BTW the Plug in card doesn't sound quite the same as the Synth itself (nor does the AN200) - the AN1x is the real deal for the AN sound and the rest are variations/compromises (even though some added features/some removed poly/different character).
