It's worth noting that the developer now lists this as "abandoned" on their website. As it currently exists, this completely bollixes Ableton Live in versions from 10.0.1 thru 10.1. If you'd like a VST that automagically hangs your entire DAW, this is for you...but I'm betting that that won't hold a lot of appeal for 99.999% of users.
The 64-bit VST2 version works for me in Renoise 3.1 and Tracktion 7. Not Reason 10, unfortunately, but no big deal. I never had a K3, so I'm not sure how it compares, but it seems to be a very nice plugin.
So many shitty things that get a 5 star review here, makes me wonder if it is someone connected to the development of the instrument/plug that passes out stars like candy. If this is 5 star what is then Synth 1, the free version of Dune/Zampler or OBXD???? Just to mention a few of the many, many free synths out there.
