Sound Synth chips manufacturers

ZeroResistance:
Are there any manufactures around for Sound synth chips.
I found only one company, called Dream, https://www.dream.fr/

Any idea why wouldn't any one manufacture these chips any more or are they aren't sold in the open market?
There are a number of products based on the Dream chip like Fluxamasynth, Nanosynth etc.

TIA

AFAIK the known synth makers like Yamaha, Roland, Ensoniq, Kurzweil to name a few, after the analog period ending late 70s begin 80s,  all made their own custom digital chips.
The synths I have seen from the inside, only few used standard components for waveform generation. It was their secret sauce recipe, not something you sold on the open market.

Nowadays it is all PCs with plugins, barely new hardware sees the light of day.

There isn't much except Dream nowadays, most audio is done in software even in hardware synths.

You could make your own synth "soft-chip" with a microcontroller though

Will these companies sell their synth chips now? Don't find them on the market though..

How hard would it be to do this, would we need a powerful MCU like the Cortex M4 to get this done?
What about any chinese synth chips?

oPossum:
If you want to learn how it is done, the lectures by Aaron Lanterman are great. Analog and digital methods are covered. How much compute power you need depends on what you want to do.
