Hello !
I was just wondering if this is still planned ? Thank you !
I love the sub phatty and would really add 3 more (a rack version if available ) to have a four voices poly sub phatty !
This could be a nice workaround for poly chaining sub phatties !

So Moog launch please a rack version for 800 $ and I will buy 5 of them 
This would avoid Moog to develop a poly sub at least …
