also thought about looking into modules for adding "randomness"again preferrable smaller modules,without getting to cluttered,but in this regard im abit in the dark
Look into random signal modules that offer multiple functions. For example, Verbos's Random Sampling module. Sure, it's $500...but in its 18 hp, you get a multicolor noise gen, the essentials of the Buchla "Source of Uncertainty", a four-stage analog shift register that can also function as a quad sample and hold, and probably one or two other things that surface once you start screwing around with it. So, it SEEMS expensive, but you'd pay about the same amount (or more) for these devices separately, and they'd take up way more space.
Also, keep an eye out for "abuse potential". Example: modules such as Euclidean sequencers don't have to be sequencers; using them as quasi-random clock modulators is equally valid, and they can be VERY worthwhile for jazzing up your timing signals.
