It’s not “new” so I’m not really answering your question but really like the original Quadra, it has a different character to the Quadrax and I dare say a different sound, like a sizzle and it’s just such a playable module in such little hp…it doesn’t hurt to have it along if you just need more envelopes. For something different that can do other things I like stages which is a goto for gate like percussive envelopes and multistage. Then there’s Maths of course which gives you a lot of other functionality. But my favorite ultimately is Quadra, with or without the big ass expander.
