> And once we have sampling technology, there’s little point using computational techniques to make the once-novel sounds of earlier synthesizers: we can just sample the instruments themselves You can't tweak the parameters of a filter envelope if it's "printed" to a sample. You might sample a variety of different envelopes, but there's still fundamentally no way you can get the sound of the filter attack gradually i…

Assuming the details of the DX7 are similar to some of the PC Yamaha FM synth hardware, you could do things like set the attack/decay of a modulating operator to be very slow, the attack of a carrier to be fairly fast, and subsequent key presses wouldn't necessarily sound the same. And with a big chained algorithm like the DX7 can do, I agree, you couldn't capture the full behavior through a sample.

You could replicate the most common behavior, though.

They also didn't get why FM synthesis was so appealing, in spite of being difficult to understand for the common musician. It's in the tone . Acoustic instruments respond in a complex way to the variation in strength of input: when you strike the key in the piano faster, pluck a string harder, or blow air info the saxophone stronger, you don't merely get a louder sound: the harmonic content , the timbre of the sound…

Beautiful summary of a rich and poorly commonly understood subject

Thanks so much!

I'm in love with my Reface DX, and have a soft spot for all FM synth. I'm glad it came through!

I am kind of still confused why the industry links „keyboard controllers“ with „synths“. there should be just good keyboard controllers that can plug into good synths (like Eurorack). What am I missing?

You’re missing MIDI controllers, of which there are plenty. :) Synth versions without the keys are often called “desktop versions”.

Very nice.

The DX7 is a musical instrument in its own right. Samplers are emulators of something else.

I have a MODX and although it’s so damn powerful when it comes to sound design - each of the 16 parts can have 8 layers each, it’s a lot of work to do anything with it. I’ve seen piano patches that sound REALISTIC because in 8 layers, you can model the hammer, the initial string hit, the cabinet echo, string resonance, and a whole lot of other timbres… but it takes SO MUCH EFFORT. So unless you’re a /real/ sound desi…

But what's the point of making piano patches that sound realistic, except as a tour de force? It's sort of a "Pierre Menard, author of Quixote" sort of thing. What I'd be interested in is how viable it is for producing intetesting, distinctive sounds, and tweaking them to your liking in a comprehensible way, not poking blindly.

pianos are enjoyable, but expensive and very heavy

If people are interested in the DX7's technical details, I've done some work reverse-engineering it, and some of Yamaha's other FM synths: https://ajxs.me/blog/tag/DX7.html Ken Shirriff has also done some amazing work analysing the DX7's sound chips: https://www.righto.com/2021/11/reverse-engineering-yamaha-dx... A really awesome documentary on the DX7 by MadFame: https://www.youtube.com/watch?v=sXt_NXjc7oY There are…

Attempt to summarize one part (the “playability”): You are suggesting the velocity curves and their interaction with the algorithms gave the DX7 a lot of its nuance?

“DX7 … before fading into obscurity.” Uh, yeah, that is quite a take. Like most synths, the DX7 went through an untrendy era, but it’s certainly bounced back and you’ll hear its patches used all over the place today. That Top Gun tubular bell patch, for example, shows up quite a bit - most recently heard it on a track called 4AM (the Fauns Remix) by Power Glove. Not to mention there are a ton of software emulations,…

Some great synths are taxing to operate and tweak in real time even if you know what is happening. So I appreciate your point about variations on the interface.

There are a huge number of MIDI controllers and keyboardless synths
