Kassen, the reinvention notion is valid, but with a twist.
Cool. I like modular synths so it's a good invention IMHO; the other people
who also invented it are generally considered to be quite clever... it's
just that they were a bit sooner. No shame in this at all.

Check. that sounds like it gets rid of many of the expensive bits. Banana
jacks are used only by Serge and (for one type of signal) Buchla, BTW.
Unless there is a smaller brand that escapes me everybody else uses 1/4"
Jack (convenient and solid) or 1/8" jacks (cheap and small). Bananas mean
grounding structure becomes quite important.

I like this idea. With large (or even smaller sized) analogue modulars it's
easy to lose track of what you were doing because the physical structure of
the patch won't always reflect the structure in signal flow.

Modules *that* small? won't that mean sacrificing things like decent
tracking for modulation CV signals?

It's a nice dream but things will only get that cheap with huge runs and
surface montage.. if it will fly at all.

Sounds a bit like a Arduino (plus a dac)? Those are about 35€ around here, I
think. Accessible but not a toy for kids. Also affordable but beyond my
budget to build Christmas trees out of...
Whew, typed a lot - as you can see I find the idea exciting. I'm working on

I like it a lot as a dream but I don't think the numbers add up on a
practical or financial level. Modular synths are large and expensive and
always have been so, to say nothing about the tuning of some types. Because
-like most people- I can't afford a decent one in terms of money and space I
once grabed my chance to live for two weeks in a studio that had some. I
took to waking up, switching on the studio, making breakfast, calmly reading
email... and by the time that would be done they'd be at a stable
temperature and hopefully the right tuning. People have been wanting to get
around these limitations for a long time. Perhaps the most succesfull atempt
so far is this;
That's a miniature modular system; quite modest (if charming) in terms of
features... and it was still something like 500 or 600€... and it probably
wasn't discontinued because they were selling it by the truckload.
I don't mean to discourage you; it *is* a very apealing idea but as a
practical product (which I sense you are after?) I don't think it will work
out. Then again; I'm neither a electrical engineer nor a salesman so I might
be way off.
