Ask HN: Introduction to Analog Synthesizers (Simulation OK)
I realized I've had a long fascination with analog synthesizers going back to the first one I saw in 1977. The band teacher had one in his office.
And I was tempted toward random knob twisting today when I saw yet another 'analog' synthesizer runnable in the browser.
But I'd really like to have some basic idea of how to put together rudimentary sounds with intent.
I was wondering about book like objects that explain the basics. Maybe a good used book to pick up. Thanks.

VCV is an amazing tool, seriously amazing. I would have never dove into modular without it as the cost to entry is just too high. VCV also nice because you can play with what you want and just ditch it if you don't like it. Can't say that when you buy a $550 module.
Highly recommend VCV + Omri videos.

I think it is superior to any book.

THis guy is my favorite professor from my school. He has posted online lectures because of COVID and decided to put it up on his youtube channel so people can watch.
back in the day this course had like 25 official seats but like 40 people would show up every day to "unofficially" audit the course.
Thanks for this
I particularly loved how he was able to be vulnerable and admit that, even with a PhD in EE/CS, he had no idea what was happening in most circuits when he started.
Mad props to that. I don't know a lot of PhDs who'd cop to not knowing something.
I've been interested in audio. I have no electronics background, so I am overwhelmed by the topic. I find there's a lot I don't understand, and a lot of tutorials online don't quite give me an understanding I'm looking for.
If anyone is looking to be inspired (rather than be informed, necessarily), check out the crazy English guy (is there any other sort?) who runs the channel Look Mum No Computer: https://www.youtube.com/channel/UCafxR2HWJRmMfSdyZXvZMTw
He's got quirky things like a Furby Organ, a 1000 oscillator megadrone, and a cryptocurrency synthesiser. He is also opening a museum soon: The Museum Of Everything Else, dedicated to old music and electronic stuff. It even includes a telephone exchange and his Googol clock, which he plans to never turn off. He also has a flamethrower synth, which he uses indoors. And he has a safety pin for an earring.
Love it.
Ultimately, I think using synthesizers does entail a lot of exploratory knob turning, even if understanding the effect of different components can help guide you to the sound you are looking for.
I got back into making music during the pandemic, partly as a deliberate choice where I turned my formerly chaotic and cluttered office/music room into something actually usable, but also through watching a lot of YouTube videos, researching, listening, and looking for a synth to buy.
The key is to get something with all physical controls so you get that immediacy of feedback in terms of the sound changing. You can hear the effect of switching between different wave forms, playing with the pulse width, maybe using an LFO to modulate pulse width, applying a filter and so on. Avoid anything that involves menu diving or relies heavily on a touch screen where you're not getting realtime feedback.
Analogue synthesis is super-popular at the moment so bargains are hard to come by - you are not going to get a used Prophet of any era for a couple of hundred quid, and basically forget anything vintage - but you can get some really good synths for not that much money, particular if you go the monosynth route. The Arturia MicroBrute is great, for example. They're about £260 new and I've seen them for £160 - 200 used on Reverb and eBay. If you're happy to spend a bit more, something like the Behringer Deepmind 6 packs a lot of punch for about £400, and the Deepmind 12 is available for around £600. (Behringer had a sketchy reputation for quality but their synth division seems to absolutely nail it - I have a TD-3, which is a clone of the original Roland TB-303, that costs about £100 new as opposed to £3-4000 for an OG 303 on the used market. Sounds spot on. Couldn't be happier.)
I'd also recommend easing yourself into it. One day I'll get into modular (it's inevitable) but I'm not there yet, and it would have been a mistake to start there as it would have been a bit overwhelming for me. You might be different but I'd say get something that, again, gives you results and immediacy - something that you can tinker around and learn and have fun with, and then take that knowledge and use it with other synths.
Sorry, not really a tutorial, but there are plenty on YouTube, which will help, but what you really needs is hands on time with synths, and lots of it. Try programming patches that you've heard on different tracks you like from scratch. For example, I really felt like I was getting somewhere when I managed to program a decently credible Tom Sawyer bass patch with a really dirty vintage-ised filter sweep. It's one of the few events during the last lockdown that brought me some proper joy.
And that's really the final piece of advice: have fun and don't be afraid to experiment. You will probably create some really awful sounds, along with some really interesting ones, but just embrace it all as part of the journey.
But I am not that committed. At least yet.
I try to avoid starting by shopping when I can. This seems like one of those. A browser is probably enough to gauge the stickiness of my current interests and avoids figuring about where to put “the damn thing.”
Or to put it another way, I give this kind of interest time. It might have been awesome to have lived circumstances that encouraged my interest of forty five years ago. But I don’t let that put me on a rush.
In my other comment I suggested that you won't find a bargain in vintage gear. That's true. However, if you don't want to be financially committed, you might do well do buy a vintage synth because you should get your money back - or maybe more - if you decide you're not that interested after all and want to sell it. Whereas with a new piece of gear, it will depreciate.
As I say, the market for these things is pretty hot now. I'm weeping that I didn't pick more gear up 10 or 15 years ago before it all became so popular. Of course, I didn't have any spare cash back then so there's that.
It’s not the spending money.
It’s that spending money can seem like progress. But not really. At least not at first. Doing the thing is progress and I can spend what time I spend that way without product research and bargain hunting and shipping and unboxing and making room for another hobby object.
And accessories.
If I find myself at the point where buying something is progress, then that’s the time, but that is statistically less likely.
I think for a beginner it’s more helpful to have as many controls as possible accessible hands on, rather than having to go to different pages and have different knobs do different things depending on context.
Analog Four is awesome as you get more experienced though as you can create a whole track on it if you are creative!
I’d personally probably go for a Korg Minilogue as a beginner these days…
Neither of the books that I'll recommend here are specifically about learning to play analog synths, but they both give a bunch of background to understanding analog and digital synthesis:
I read an earlier edition of this when I was getting into working in electronic music, and found the background very useful and a pleasure to read.
https://www.amazon.com/Electronic-Experimental-Music-Thom-Ho...
This one is specifically not about analog synthesis (but rather digital synthesis and sound processing), but is kind of a classic in the field:
https://mitpress.mit.edu/books/computer-music-tutorial
The most common physical analog synths have two to three oscillators and a resonating filter. The first book would give you enough info to know what that means and begin to explore the space a little more intelligently.
Assuming you're a programmer, you can also do a lot of things by creating synths using either a visual or code-based synths on your own. I'm partial to ChucK, but there's also Supercolider, CSound, Max, Pd, Reaktor, ...
Warning that modular synths are typically not cheap. However, most of the physical standalone synths that exist today use the same principles.
Physical hardware can be really fun if you don't end up going with VCV rack or syntorial as mentioned in this thread.
Good pieces of hardware for a n00b:
- arturia microfreak
- korg minilogue
- any of the korg volca lines

Getting "the sound in your head" coming out of the machine takes lots of practice, but this really, really gives you a running start.
This guy has a channel where he builds up analog synths from basic components. He does a great job explaining the intuition.
If you want to follow along with your own synthesizer, there's a breadth of options ranging from software recreations of the 2600 to a licensed hardware reissue, but for $25 you can get Cherry Audio's respected CA2600: https://cherryaudio.com/instruments/ca2600
So if you go the route of buying a broken one and restoring it make sure you refresh all of the caps that are across the voltage rails (of which there are quite a few).
- Learn some music theory
- Learn some signal / information theory
- Synthesize!
[UPDATE] Here we go: https://learningsynths.ableton.com
There is a lot of science behind audio and if you are that way inclined, learning about it is really worthwhile. All those effects create the sound they do for a reason.
I know that there is a semantic difference in technical contexts. It doesn’t bother me. It’s a true-enough Scotsman.
The distinction for me is with sampling synths (which can also, though rarely be analog)…I mean I have a forty plus year passing interest and the personality to gravitate to HN.
I am more interested in the empirical part. And digital has some practical advantages like using my iPhone.

That way you're doing the same stuff you would in a pure analog synth, and getting similar sounds. In the digital realm there are lots of other ways to make sounds: FM, additive, samples, physical modeling, etc.
Pure analog synth hardware had fallen out of favor by the turn of the century but since then it's made a comeback.

Once you get the basics down, when it comes to real sound design I've found the best tool is to get on YouTube and search for "<name> sound design" where <name> is the kind of sound you want to make: spacey pads, EDM pluck, dub techno stab, 90s synth bass, etc.
Over time, your ear will get better at hearing a sound and understanding how to build it in a synth. You'll learn to hear the difference between a sawtooth and square, what different filters sound like, and how detuning, unison, PWM, etc. all affect a sound. Tutorials are a good way to build up that knowledge.
Also, just like programming, there is absolutely no substitute for just sitting down and noodling with it yourself and trying to make sounds. Like cooking, much of the learning happens in the intuitive non-verbal part of your brain. You don't just need to learn the words for things, you need to develop a deep auditory intuition around sound. You need to feel it. Books will only get you so far with this. Making sounds yourself is key.
You can do this all on a computer using software synths if you want. You can get a free or cheap DAW like Reaper or Ableton Lite and then a free soft synth like Tytel's Helm.
But, personally, I think it's more fun and easier to learn on hardware. That lets you engage your sense of touch and muscle memory, which helps really lock in the learning. The Korg Monologue is a great analog subtractive synth to start with, or a Minilogue if you want to play chords. Hardware holds its value really well, so you can always sell it and recoup most of your investment if you lose interest.
Note that subtractive synthesis is just one way that machines can make sound (but it happens to be one of my favorites). Over time, you'll want to explore FM, wavetable, additive, granular, etc. There's a ton of fun to have.
