I had a dx7 in college. Its an FM synth, an from the little diagrams on the top, it was fascinating. I could make my own sounds, but I never could get the time to get programming (beyond detuning the sound and doubling it to make a "fatter" sound, the dx7 had a gray matter mod chip). Lamentably in the 90s information about this stuff was harder to come by, plus the 2 line led screen to input things wasn't ideal. You can see the top of the keyboard images here: https://soundprogramming.net/synthesizers/yamaha/yamaha-dx7/ https://soundprogramming.net/synthesizers/yamaha/yamaha-dx7/ But the internet abounds with sound making tools! ableton has a synth basics online class/demo kind of thing: https://learningsynths.ableton.com https://learningsynths.ableton.com visual programing sound machines in pd http://www.pd-tutorial.com/english/index.html http://www.pd-tutorial.com/english/index.html Also the GDC talk by the sound designer of doom (the new one). He's using sine wave, and a bunch of effects boxes (some in parallel) to generate all those sounds. There is also a sound morph tool they used to combine sounds with a chainsaw sound... The talk starts a couple minutes in after a doom sound trailer thing: https://www.youtube.com/watch?v=U4FNBMZsqrY https://www.youtube.com/watch?v=U4FNBMZsqrY

Dx7 is such a rad synth!! I had a few vintage synths when I lived in New York but sold them due to space. Just started getting back into it and there is some really cooo hardware out there. Especially digging the Elektron line right now. Picked up a Digitakt which is a funky sampler / drum machine / sequencer. Has allowed me to drive my synths via midi without using software or a laptop. Very refreshing and a totally different workflow.

You aren't alone. Almost no one could figure out how to program the DX7. Even today with the resurgence of FM (Digitone, FM8, Volca FM, etc.), it's still just a really unintuitive way to build sounds. That's not to say it's a bad, or powerful way, it's just really hard to build a correct mental model of how changing parameter X will affect the sound in the way you want.

  Aphex Twin figured out how to program his: https://magpi.raspberrypi.org/articles/aphex-twin-midimutant https://magpi.raspberrypi.org/articles/aphex-twin-midimutant

    wow.. That is a good use of a pi. Though the button labels are a little odd (given that its a genetic algorithm..)

    I can't tell if that's an argument in favor or against my claim. :) If you have to have a brain like Richard D. James to grasp it, what hope is there for us?

  ALM makes some eurorack modules that are fun to use and sound great. This one provides 4 operator digital FM using ‘new-old-stock’ Yamaha ICs: https://busycircuits.com/alm011/ https://busycircuits.com/alm011/

  I was something of a synth expert in the 80s. Built my own analog synths using Paia kits, used giant wall-sized modulars with rats nests of patch cords, programmed Arps, owned a few Korgs. Later I learned the Fairlight, hooked two of its channels up to galvos and did laser shows with it. But I could never figure out the DX7.

  There is a new, very nice sounding open hardware FM synth running on a Xilinx Artix-7 FPGA chip that I really want to build (by René Ceballos, creator of z3ta+) - https://www.futur3soundz.com/ https://www.futur3soundz.com/ But yes - it has 400 parameters, programming the sounds isn't going to be easy! I wonder if you could use a neural network to map many parameters into a reduced set of useful controls. Advanced physical modelling synths can have the same issue - too many parameters to meaningfully control while playing.

I am a huge fan of FM synthesis; it's wonderful for making growling bass sounds as well as drum/wood/metallic sounds as well as keyboard, brass, harp/guitar and string sounds and bizarre screaming out-of-tune noises. And of course the (in)famous DX7 "piano" sound. If you want to keep it simple you can use it similarly to subtractive synthesis - instead of using a lowpass filter you can just reduce (or increase) the amount of FM on a single carrier oscillator. I had never owned a hardware FM synth (though I was intrigued by the Volca FM) but after making many dozens of sounds on iOS FM synths I actually bought a vintage Yamaha TX81Z for cheap on eBay just so I could have fun with a hardware instrument. It's Yamaha's simpler 4-op design (with extra waveforms to compensate) and it's a fantastic instrument if either a) you can deal with the tiny display or b) you program it over MIDI using an external editor program. I think it was designed as a rack ensemble of sorts as it is 8-voice multitimbral. It also came with a cassette tape (!) containing the sysex data for its factory patches. ;-) For anyone who wants to try out a free/open source DX7-like software instrument, you may want to check out Dexed: https://asb2m10.github.io/dexed/ https://asb2m10.github.io/dexed/
