Regarding the mixer. As you already have an x-pan, you could stick with the make noise schema for mixing and grab a moddemix to add to the case. I like to use the moddemix and optomix as a sub mixer before inserting it into the aux in on the x-pan. So rather than having 1 large mixing module, you can cascade submixers throughout the case and still have the benefit of the other functionality they add. And as mentioned above, maths is great for this as well.

Thanks Wm

Checked out the Moddemix and this seems a good idea, yeah think I would like to keep with Make noise stuff now if I can! I want sure if best to get a large mixer or go down different module route but this is wise since I would have other functions, learning all the time lol! My original plan was to get the Shared System but decided to get case and slowly build it myself and maybe change a few things on the way once I gathered more info on Modular and what I want. But I would like to stay close to it but with the new modules like xpan and Mimeophon. Does that make sense

Thanks
