Capacitors are more stable, less temperature sensitive, have less parasitic inductance, higher breakdown voltages, and the electrolytics are a lot less toxic.
Resistors have better specs and less noise -- a lot of the old synths were built with 10% bulk-carbon resistors. I don't know if you can even get those anymore. Arguably, transistors have improved, although fans of geranium transistors might disagree (but that's mostly the guitar-pedal crowd). Power supplies are more reliable and better filtered.
it was better and better...just until the beginning of the 90s. Then all began to go downhill again.
70s potentiometers had the thick carbon layer, but 90s the pots have just some carbon dust and dont last so long.
Production was transferred from Japan to China, but capacitors produced in china is a major headache which takes down the whole production quality of the items, power supplys design went cheap and troublesome if they began to use impulse PSUs on everywhere. On those places the capacitors are very eager to go bad.
There are fake capacitors, also bad capacitors.
INtroduction of the lead-free soldering made extra troubles.
Is it nostalgia? Well, partly. And yes, you can be nostalgic for a place and an era you didn't actually experience, whether that be sailing ships, coast-to-coast passenger trains, Glenn Miller at the Savoy, or Edgar Winter with a 2600 keyboard slung around his neck. Is nostalgia good or bad? Well, sometimes it's beneficial to put yourself in the place of someone from another time, by experiencing what they experienced. And sometimes it's beneficial to re-explore the past to see what was left undiscovered the first time. There's value in just seeing "how it was back
I use the synthesizers and stick to those with MIDI, however I really dont miss the modular era or the hord of the
cables and "wall of sounds". My most favourite sounds are from FM synthesisers still.
I use the hardware synthesizers becouse of the sound and it is more practical than computer with VSTs as I dont have to be this way in a endless "upgrade" cycle where this or that program or platform renders my old bought software obsolete. The way how in comptuer it is done nowadays is really offputting as everything is done like programmers hate their customers, the end product and computers.
So for me it has been in hardware 3..4 steps forward (patch memories, multitimbrality, Sysex), and one step back, but about computers and sequencers it is always one 1 forward, 3 steps back if looking what and how it was the last 20 years.
Which means that I certainly have a way much more use of the Yamaha TX802 unit in a longer run than these VST counterparts becouse just they have compatibility problems which are purely by software company policy of greed.
I never miss the hiss of the sound, also I do not like all these digital grainy emulations of analog sound.
SUmmation: I see that the whole problems are induced by marketing greed where they try to deliver for market what
market demands, but the companies introduced whole line new problems with the will to make production cheaper, maximize profit and so actually faking the products.
