On the basis of the subject title alone (Analog synths are now craftmanship), I respectfully disagree.
Years ago, PC boards were done by hand. Craftmanship.
Today, one can draw a schematic on a computer and it can automatically generate a PCB from that drawing.
The parts of the past were often much stronger.
Many were first designed to meet military specs.
There was hardly a US consumer electronics industry for a while.
If you bought a portable AM transistor radio then, there was a good chance it was made in Japan.
Why? Because US components were larger.
Same for cars too: eariy US cars were always bigger than early Japanese cars.
But these are just isolated, arguably comments above.
My larger concern regards construction and all-around complete designs.
Today there are people building synths that have no idea about RFI emissions.
Some are clueless about mechanical engineering despite then being little Einsteins in EE design or programming.
Many don’t understand basic electronics and have learned only what they needed to get from point A to B.
Say “induction” to them and they make look at you like the RCA dog.
For example, they may make a Tesla coil, but have no clue about high-frequency/voltage burning and emissions both at their core and resonant frequencies.
In short, they’re not well-rounded engineers; they’re talented and applied DIYers often with some business acumen.
This is no slams to them at all though. It’s a criticism based on the public perception that older and newer things might be equal.
Indeed they may be equal until someone tries to export their wonder-goody to another country and finds themselves amongs ROHS or FCC compliance demands.
And if you think I’m just a big bag of woe here, think again.
I’m digging seeing what many people are making today.
Yesterday’s engineers were rarely artists.
They followed directions and procedures to build something.
Without such frameworks in place, today’s builders can enjoy journeys through creativity unencumbered by rules.
(I draw the line at some circuit bending tho. Currents and voltages don’t know Picasso.)
So anyway, my opinion is that our technology is far advanced over yesteryear, but that many of today’s offerings are constructed much more poorly.
Not built to last time, nor everyday repeated usage.
Where yesterday a maker might only have one choice for a particular switch, today the common denominator can be price and with that thinking, quality goes the other way.
I’d love for those that haven’t had the opportunity to compare, say, an Arp 2500’s parts to many instruments today.
You’d find the older devices used metal shaft pots, instead of plastic and on and on.
No, today’s analog synths are not so much craftmanship (exceptions withstanding), but moreover they’re now far more controllable and capable.
I’d rather be in an accident in a '57 Chevy against a 2013 Kia.
