Hey Garfield,
I pre-ordered the Disting EX from Signal Sounds in Glasgow a couple of weeks ago (Jason said the new stock had been sold before the units arrived in his store) so I guess I was lucky (and impatient ;)).
As the tagline goes, the EX is (also) like "two souped up" mk4's because some mk4's algos have been reworked and now have much better audio quality and processing. To me though it's the single modes that make the EX a wonderful module. I thought the Matrix Mixer is something I'd never want to use but the 6 inputs/4 mix outputs and 60 (!) tweakable parameters turn the EX into a complex CV/audio mixer. Then there's the SD Multisampler which I was tweaking last night (plan to post a video demoing that algo as well) and I find it so awesome (up to 8 voice polyphony, polyrhythms, etc. - and it sounds great!), the Augustus Loop stereo tape delay is also very complex. And there's a lot more to discover here. The tiny OLED is really useful and with the EX you can't escape menu diving but it's quite convenient and with 256 presets on board you're pretty much covered.
Like I said I still have two mk4's and plan to keep at least one for good. It's simply too good a 4 hp module to let go of. If one can afford it, having an Ex AND one or more mk4's is fully justified, imo. Hope this helps.
Best wishes,
Gabor
