Maybe this goes in “Questions”… I’m not sure.
On first seeing/hearing Todd Barton’s Krell Muzak some 3+ years ago, I tried to replicate it with the modules at my disposal, with a reasonable degree of success.
The one thing which I absolutely could not work around or emulate was the heart of the whole thing - the Buchla 266e Source Of Uncertainty.
Since then, I’ve done (what feels like [1]) extensive research into what’s available in Euro format, as well as exactly what it is that the 266e does (still somewhat unclear, as it’s proprietary), but I’ve yet to find anything which I think is “the same”, specifically: voltage control over probability distribution - this seems to simply not exist in Eurorack, or for the most part at all outside of the Source, and I guess that’s part of what makes it unique.
So, the actual point of this post: prove me wrong. Or, much less aggressively, help me find something which has the character of the 266e in terms of being able to automate changes to the probability distribution of it’s randomness.
Some secondary criteria: Eurorack, in case that wasn’t clear; I prefer DIY and analog (somewhat flexible); cost is definitely a factor.
Bonus round question is to compare the Wogglebug (in it’s various incarnations) with the Swamp; they seem like something which while maybe not that close to the 266e, nonetheless maybe I could live with, but I don’t know how they differ…
Thank you for your consideration 
[1] I’ve researched the Sauce of Unce, the Wogglebug, Erica’s Swamp, and numerous modules with “Random” or “Chaos” in the name…
