You got quite some nice fancy modules in this rack ;-) That's nice to see but it certainly has disadvantages too...
Depending on what you have already, but assuming here you have no other devices just that what you are planning here in the above shown rack then you got yourself too many fancy modules planned and too less classic and basic components like oscillators, LFOs (okay I saw that Doepfer A-145, that one together with the Moog that might be enough to start with), filters, envelopes (yes I saw the Maths but that one is too nice to use just use it as an envelope; of all the fancy modules at least keep this one, nice module), VCAs, audio input & output module and in your cases you might want to check if the Moog can be directly used with a Eurorack system, if I am not mistaken that's not 100% compatible, so better check that first before you start.
You also got far too less space. So why not leave the Moog out and put that back in it's original casing, that saves you a lot of space that you really will need with the above mentioned modules.
Regarding the music you like to create, I have no experience with that so can't help you there, perhaps other members can give you some advice into that direction.
Oh yes, I forgot to mention the Make Noise MMG, are you sure you are still able to buy that one? I can't find it with my regular dealers, so you might want to check that too.
Kind regards, Garfield Modular.
