As for the poll regarding a 1.2v converter module, I guess I was on the fence. I would have bought it given that Doepfer modules are always reasonably priced, but I would rather have had a dedicated module with more voltage processing (hence a wider audience wanting it) or a Module Module version (that's a third party format devised by Eardrill where 4 smaller "module modules" fit in one regular sized Buchla module frame).

Actually I've been meaning to do some interfacing. That was my original intent when I bought some Buchla modules but then I planned my system fairly carefully and I wound up with a long wait for my order and then a whole system. So then at that point the desire to bridge out of the system was more one out of curiosity than something I had to do. As for the 258v and Euro (it's a clone of an early 1970s Buchla dual VCO), I don't know, I have a couple Plan B Model 15s (inspired by the 258)

I guess I'm writing because I sort of take exception to the "elitist" approach claim regarding Buchla. Why I think that is the attraction to Buchla is he developed a sophisticated synth system without encountering a Moog Modular and at nearly the same time. So it opens the debate over if a company is obliged to later offer support to some other format on the basis of more people are buying it. Though I guess with the proposed Doepfer module is kind of the other way around. It does seem more like a third party thing.

But anyway it does seem like a good accomplishment that Buchla today is fairly backward compatible with it's own legacy modules and the 1.2v certainly wasn't arbitrary, it was even forward looking in that you have .1v per semitone. It makes octave switching less convenient but generating pitched voltage scales easier. EML went that way too. Then again in the triggering department Moog's S-Trig approach wasn't widely embraced and I'd say Korg really went elsewhere. (don't forget their triggering is different too)

Actually while thinking about the pressure to change or add to a system's standards because other companies went along with a sales leader, does anyone have the month and year of the A-100's public showing and modules available for sale as well as Analogue System's RS Integrator dates I'm curious for the historical sequence.
