I saw your updated skiff. I don't think MG has updated the JPG yet... but it has changed since your original post.

I own Maths. I like Maths. But at 20HP, that's a lot of space for this skiff. Also, as Luiga mentioned, that buffered mult is a nice-to-have. But it really won't make a difference for the size of this skiff. For this size of a rack, every HP is important. So how are you justifying the Maths and the buffered mults?

I also noticed the Duatt. Good choice. If you get rid of the buffered mult, you'd have room to add back in your Mosiac ADSR.

As always, just suggestions.
