Any specific reason you have avoided modules like Rene, Metropolix, Trigger riot, A-155, and similar modules?
Hunterprime, yes, it's because I planned to start out working with the Beatstep Pro and The Oxy One. That way I could concentrate on sequenceing some specific melodies as I learn the rack better. Then once I have a good understanding and some time under my belt on it, then there will end up being a 4th rack added that I will fill up slowly with modules in areas I find I'm lacking in, new releases, or possibly deals I come across. I've looked into the sort of modules you mentioned many times, and ultimately it's the size that was a big factor. After looking at every video I could find on modules of that sort, Trigger Riot was the one that caught my eye and I will almost certianly be one of the fist to go into the 4th rack. It does look like a lot of fun! (I also like that it doesnt have a micro screen which was the downside of the Metropolix for me.)
I also personally think that keeping the MN modules like MATHS, XPO, DXG together is going to give you massive bang for your buck. Maths in perticular, pairs beautifuly with the DXG and XPO

MN does seem to aim for making modules that complement eachother well.
My layout of the modules will surely be diffrent than what is shown here. It'll just take a bit of time to see what I end up useing the most, what makes it easy for my fingers to fit, and what just seems to make sense.
