to my knowledge it ain't a buggy plugin, and bugfixes are always quick. windows 10, by the way. also for mac. at this moment 3.14 works unproblematic.
report in the right thread, or to the developer. and fixed.
it can be system specific problem, my OB-Xa (arturia) crashes cubase pro 11, i am the only one, but arturia really tries to help, a lot..
always try the demo, discover it for yourself. the demo has no real limitations, only time out or something??
the GUI i must agree, you must learn, but it isn't melda, but that i also like... learned to like..
but in the end all is very logical.
EDIT: i do you use Vaporizer 2, with great pleasure, and my go to wavetable synth. stable. MPE is great (how release velocity is implemented..). always personal of course, what you like, but i wouldn't trade it for ... also personal..
so discover it for yourself, as always. was it buggy? a lot has changed, even the basics of the oscillators, anti-aliased by definiton, by the way, as other wavetable synths that use FFT/additive.
a lot of bugs are squashed, but some where quite esotoric..
o well, i must admit, i am quite into vaporizer 2, and the responsiveness of the developer is great, a lot of FR (MPE..) where implemented, while at this moment, the response time is somewhat slower..
i like to support developers that make a great product, are willing to change, even fundamental things, for the users. implement a lot.
but that is my personal experience. it is up to everyone themselves, of course, it is evident, to judge is this plugin the synth that get's me going.
