Another way to explain fm synthesis is to show how it occurs in the real world. Eg. when you strike a bell, cymbal or guitar string, the energy travels through the metal as transversal waves that bounces of the edges and intermodulates in much same way as a fm algorithm.

Thanks for the shoutout, Bo. Excellent in-depth video. Your visual style is noteworthy, too.

Perfect timing, I grabbed a second hand Volca fm just the other day to dip my toe in the fm waters 😊 . Love these types of videos from you @BoBeats!

Hey Bo I've been playing music for 7 years and producing for 2, and your videos have greatly helped to not be afraid of and understand synthesis, plus your reviews are the best, Thanks!

Hey men, as a french who dont really speak very well english. I understood everything thanks to your good diction. Thanks a lot !

I've been composing music and making beats for quite a while. Thank you for explaining this and introducing me to something I should have learned about years ago.

Haven’t seen your new uploads in my recommended lately, I saw this and immediately clicked. I’m an fm fanboy as of recently, so this is great content.

You're an absolute savior, I learnt quite a lot and own a MODX so it's just perfect :) Thank you Bo, very nice video!

The way I've tried to understand FM is to just examine one operator (OP) and one modulator (MOD). The OP is the part we hear, starting with a pure sine wave with the first gen FM synths, like the DX7. The MOD is a bit like vibrato, but higher frequency. As the frequency rises, more harmonics are introduced. This is in a way the opposite of an analog subtractive synth, which starts out with harmonically rich waveforms, then using the filters to remove some of the harmonics. The complicated part is how the envelopes of the MODs interact. The algorithms (ALG) are different recipes for how the OPs and MODs affect one another. You can stack 6 sines with no MOD interaction to create a simple drawbar organ model. I think from memory this is ALG 32 on the DX7 (or Dexed, Korg Volca FM). I can't remember exactly why, but ALG 14 is great for bass. One method I used to use was just change OPs and see what happened. Occasionally this led to some very happy accidenta. One positive of FM is that it is difficult to get tired of it. You could study it for years and still not reach the bottom of its sonic potiential. A good antidote to GAS (Gear Aquisition Syndrome).

Great Video. Thanks for your easy explanations 🙌🏽

Such a clear, excellent demo/tutorial on a much misunderstood subject !

So far the best FM tutorial

I've used FM a lot and it really isn't as nightmarish as people think it would be. The most important part that people ignore is the level scale. If you want a balances sound in all the ranges you should learn how to use it. It's a bit like a keytrack but more flexible and useful as it has curves and sometimes a break point. It's best to start at the break point, which may be centre by default, as this area changes the least with level scale amendments. This is because this is the start point and as we get further away the curve can have a wider range. So get the tone right at the centre. Now go to the highest range and change the levels scales (it's basically another amplitude amount of the carrier/ modulator) and try decreasing some of the weird and annoying digital sounds you may have. This makes for a smoother and more natural sound. In the lower range increasing the same digital sounds can add much needed harmonics to make the sound less muddy, and add a lot of phasing modulation which sounds good. You could also use level scale as a type of EQ. You could have one carrier/modulator to be used specifically for each side of the level scale.

This seems to be one of the things which divides people of the synth world... MO-DX or MOD-X... (it’s MO-DX by the way... :) and I call my MODX7 as the MO DX7... as I just want to have the DX7 as a part of the name, even the 7 in the MODX only refers to the octaves of the keybed...)

Amazing ❤️

Thank you Bo for the well done explanation. I had a Yamaha DX21 in 1991 as my first synth. I always said "This thing is made like a tank but whoever designed the language was a sadist!" LOL!

A really good tutorial and ease of understanding. This is good info, helped me better understand FM and also the additional resources Bo points out are a great help. Clear, concise, and straight to the point. Bo has done it again! Bo makes a good point here, the carriers need to be highlighted by a different color in the MODX in the number block, this would help in ease of workflow in creating a new sound in FM on the MODX. This would seem like a simple change that could be made by a future update that would greatly improve the MODX especially for folks like me.

Hey Bo, great presentation on FM synthesis....your intro is so dead on. Some of us know very little about synthesis....like almost nothing lol You did such a great job of introducing and explaining the FM format so that anyone unfamiliar could understand it.... Excellent work!

Additive synthesis and subtractive synthesis is like the inductive logic and deductive logic of creating sounds.

I hope one day we get some crazy DX synth with like 10 operators and a knob per function interface....but such a synth would need to be bigger than an OB-Xa.

The Volca FM is better than I thought once I used the Synthmata online editor. I've made sounds in Dexed and sent them to the Volca FM but they don't quite sound the same. I think the best solution is to do the midi out mod. Make a sound with Synthmata. Save it to Dexed. Sounds like hard work but I feel you'll be able to get the best out of the Volca FM this way in terms of making original sounds.

nice!

Is it Frequrency modulation or freaky modulation?

Thanks for the intro video. On the MODX/Montage, can VCFs etc. be used on the FM sounds?

An editor is basically essential for those older synths if you want to have any fun with them. BTW, I love the V50, mine's in storage on the other side of the world right now but I miss it. The keyboard feel is my favorite of all the synths and controllers I've owned, though everyone prefers different things... For those that don't know, it's basically 2 TX81Zs with an effect module and drum machine and sequencer wrapped up into a keyboard.

I've been considering Akemie's Castle for my eurorack. We're talking 5-voice polyphony potential in 38 hp! Not too shabby, but since the Castle has no heads-up display, I wonder if the dial-based interface might actually make FM tougher?

Great demo and explanation. One thing still not sits well in my brain is what exactly the modulator oscillators modulating in the carrier? I do understand when you use LFO to modulate pitch (it modulates.. pitch). In modular synth its very clear what each module modulating because you manually patch it. But in case of FM synth the modulation parameter is usually can't be changed (like in DX7 or Dexed) right? So what does it modulating? Is it the frequency (like the name FM suggests :/) but then isn't it just adding to frequencies on top each other basically addictive synth? I mite said a bunch of nonsense so sorry in advance still very new to synths. Thanks :)

@BoBeats

Жыл бұрын

So if I understand the question correctly: You are modulating the pitch of another oscillator using an oscillator. That is FM at its core. So you use one oscillator so add harmonics to the sound of another oscillator (remember, an lfo is a really slow oscillator!). Hope that helps

@eli-shulga

Жыл бұрын

@@BoBeats "You are modulating the pitch of another oscillator using an oscillator" thats exactly what Im not fully understand. So in all FM synths (which don't let you control of what the carrier is modulating) The target parameter changed is the pitch? Also, does pitch and frequency are the same thing in this case?

Me watching this to try to figure out Fm so I can start making music on an old soundcard with Yamaha OPL3 chip and it's 2 operator synthesis. (thought there's is also a 4op mode but that also eats a sound channel)

Hi, where shall i start as a beginner ?

To make a long story short: it's basically up to experimentation lol there's no way to predict how the modulations would work outside using pure sinewaves and even then when there are too much of them it becomes impossible again

@@BoBeats hello Bo! 👋 new subscriber here. thanks for the amazing videos :)

Me personally find claim "FM synthesis is difficult/complex" is at least controversial. Any synthesis if it's not trivial (like just passing saw or square through LPF/HPF/BPF/etc) is difficult. For example, If you're passing oscilator through a distortion or a saturator, even if it's just a regular hard clipper or tube amp (emulated or physical) with just one parameter "drive" it depends a lot on the phase response and frequency response of the signal what you'll get as a result. It means that if you'll put an allpass filter between a generator and a distortion you would hear the diffirence if and only if the distortion is not bypassed. If you're mixing two oscillators and they're detuned, it will cause filtering because their phases are not aligned. Chorus, flangers and reverb also create a lot of phase cancellation along the spectrum, etc.
