That’s funny, I love the sound of the current generation of Curtis filters, but I also like many other filter styles and types too. Each of them offer their own sound. And I find on the Rev2 especially, the filters are super super smooth and lush sounding.
To my ears, there are many different implementations of Curtis filters and not all of them sound the same by any means, even if they use the same chipset - this likely has to do with things like internal drive level, osc. harmonics and other interactions, and possibly even impedance loading, etc. of the chipset. So, personally, I don’t like or dislike Curtis filters any more or less than any other filter architecture, I just really love them in the Rev2, just like I love my Moog filter in my Subsequent 37. I even really like the digital filters in the Nords… to each instrument it’s own timbre, and a filter to go with it, I say!
The thing I really like about the Rev2 is that it doesn’t pretend to be a Juno or Jupiter, but it has its own, beautiful, and very entrancing versions of those sorts of nostalgic sounds. It’s not “too clean”, and it can definitely be “dirtied up”.
But there’s nothing wrong with not liking the timbre of a certain instrument either, so really, let your own ears be the judge! (And choose good headphones or monitors to listen on - I can’t tell you how many times I’ve had friends say they really didn’t like a certain synth and then have their minds blown when they heard it on better speakers – or vice versa!)
