Interesting to find out when.Not a super big fan outside a few patches from ARP, CS, Continental and Mini Vs. I've owned so much of their stuff but ended up selling most of it. I have Spark, which is probably one of their best imo.
Like I mentioned, I don't want to come down too hard on Arturia, because I can recall off the top of my head certain patches I'd rather not live without.
I think that the u-he stuff sounds awesome.
But Arturia updated their older stuff to V3, changed the filters etc.
The new stuff, on the other hand, is in another league. Take their emulation of the buchla easel for example. It taxes your cpu and for a good reason.
As for NI, well it depends. You got instruments such as Monark which sound amazing.
