Mad_Cyril …yeah, the master ISO isn’t really for mixing per-se, more for messing with track frequencies over a big system… you’ll see the likes of Claussell, Krivit etc. wanking themselves daft with them, which personally I think sounds shit, but horses for courses, used more sparingly they can be quite effective.
The HPF on the Radius is basically a super-smooth subtractive filter… removes the frequencies from low>high as you turn it up…. it’s really all you need for mixing house/techno and is why lots of folks with Xone 92/96’s and Rane MP2015’s scarcely touch the EQ.
NasserAlazzawi …the valve will sound incredible, but I wish they’d just do a valve Radius, you really don’t need EQ’s/Xfader on a mixer of that type (but then I guess they’d have effectively re-made the A&H V6, which they might be reluctant to do).
