[@PatrikČerný-n3u]

You have SOOO BIG Talent in explanation. This is absolutely BRILLIANT. THANK YOU !

[@samusbros66]

Bro, bro u have improved my mind, listen a wave just watching it's mind blowing, thank you very much for this tutorial

[@giordansprock7787]

Cheers for the amazing video dude! Have been struggling to fully wrap my head around FM synthesis but this helped so much!

[@mitchelldavid2916]

this is awesome man, thanks for explaining so simply!

[@gudgejm]

As someone who's trying to understand FM it made me super confused how people actually used phase modulation so frequency was different than i would expect it to be, this video cleared this up for me, thank you so much! Big thumb up

[@그렌다이저-u9t]

OUTRO TRACK IS SOOOOOOOOOOOOO GOOD

[@basho5493]

Great vid!

[@Ghosthack]

Thanks!

[@DaddaPsy]

Very well explained! I think you kind of put words on something i subconsciously understood. Considering that FM something where the modulator signal is pitched very low, you can "hear the actual movement of specific shape". This is very fun to do with the noise oscillator by turning the pitch down in it and let it modulate OSC A or B

[@dcodex2376]

dope thanx. stoked on Massive X and PM, it's kinda like it has an extra two OSC's for modulating VS the idea of MOD targets in Serum, then the noise OSC you can load any sample like Serum has it's noise osc too as a MOD target. This is probably a reason I've been having so much fun with it and why it feels so fresh,(and crazy how they all blend well) and finally wrapped my mind around the custom LFO ratios and preset shapes, at least sorta ugh workin on it!

[@ELMNTALV1Music]

Best explanation iv heard

[@DWinters]

Very helpful explanation, thank you

[@sheilavandeweerd]

wauw this video was so good! thankyou

[@MaikSchott]

Very good explained! Thanks a lot.

[@chekromlek1918]

you help me to understand the phrase a lot

[@gentleuproar8297]

Wow dude that was sick! You break out the crayons!!!! No crazy terms but you still tell us what's going on.

[@gri_sh5081]

Very Informative, Thank you !!

[@Eric-Marsh]

Good explanation - thanks

[@Freedomintertainment]

That was excellent teaching

[@fano72]

Ok cool. But WHY is phase Modulation actually preferred by most plugins?

[@theunconciousmind7314]

i agree you should have both atleast linear fm and phase mod, like in pigments. the reason they made it phase mod i think is for the purpose of creating more glitchy textures and wavetables...

[@tailsandwings]

Modern computers calculate sine from a taylor series approximation of only the first quarter of a sine wave, which is then mirrored and flipped to make the whole wave. So at the lowest level the time value is already chopped up into repeating linear ramps of a quarter of the period, which are then transformed by the taylor series to look more sine-like. In a software synth, full period ramps are made with accumulators which add a small value at each tick (usually 44100 times per second) until they wrap around back to 0 at which a new wave cycle starts. The slope of the ramp at each point in time determines the pitch. This makes it possible to vary that pitch at any moment without glitches by simply adjusting the slope while the accumulator keeps on counting. - That's just how a basic oscillator tends to work... Because of the math used to describe FM and PM (from the time it was used in analog radio), using the slope to determine pitch is called PM. So even if we only vary the pitch of the oscillator itself this is already PM under the hood. If we then sum a carrier and modulator pitch first, making it look like FM from a higher level, it's technically still going to be PM. If you really want it to be mathematically-certified FM, you'll find that the math behind FM requires you to know the shape that the modulating signal will take, define a function for that and then compute a finite integral of that function for each sample point, which is annoying if you expect a user to change a knob while playing expecting to hear the change right away, which means you need to create a small windows of time in which you create function (probably by polynomial approximation because users with knobs can be unpredictable) to be integrated (ok, this better be a very simple polynomial) and unavoidable adding latency in doing. I suspect that this will make the average DSP programmer go "Nah, not going to bother... It's much more fun spending that time swapping out the taylor series with a wavetable and make this synth do much more than just pure FM/PM..." Now there may be a case where you specifically want to model an old analog FM synth, taking it apart, measuring response of each resistor and so on. In this case you're basically programming a sort of virtual machine that painstakingly emulates FM. But any producers I know would rather have the raw creative power from something like serum and leave the adding of subtle harmonics from emulated (or outboard) gear to a mixing engineer or quickly slap on a bespoke LA-2A emulation for that coveted placebo effect. I hope this provides a bit of an answer to your question why PM is preferred ;)

banging video thanks so much mate

[@eiis06]

i love sound design

[@lavicho.5184]

deserves more views

[@7ktraxbeats118]

Great video 💯

[@Garbagepaildumpsterfire]

This was very helpful! tysm

[@michaelvaughan2888]

great video, such a good explanation, makes perfect sense

[@pheymee88]

What a discovery! :O I'd never doubt it's actually not FM :O

[@jackgrothaus2722]

Thanks I understand calculus now

[@flyoverfredusa]

super helpful

[@brianenrhrj9299]

youre amazing dude ive learned so much from you ( :

[@shaylinsuren1027]

very clear explanation 👍🏽 thanks!

[@carlosperez8321]

You're da best ma g 👌🏻

[@blindcamel6236]

so why does serum's knob say FM if it's not frequency modulation?

[@MikeRenouf]

This is a really interesting video and very clear explanation. I think the answer to your question is simply that the mathematics required to create FM synthesis effects in a digital environment is best done using the technique of phase modulation. It provides near enough the same sonic output, but is more easily coded than using actual FM. I'd be happy if someone corrects me or gives a better explanation. 🪐✨

[@ColdRane]

Thanks man!

[@sirmatthewbaum]

youre a beast

[@Youcantdoxxme]

amazing

[@vnyk8357]

very well explained! i lloved it

[@EyalKomorovskyOfficial]

thanks

[@sebastiendas]

why are diagonal and horizontal lines outputting one singular pitch? shouldn't the diagonal one be changing?

[@EyalKomorovskyOfficial]

What actually happens that sounds like clicks when a square wave does PM?

[@theunconciousmind7314]

this took me a long time...

[@ArtfulRascal8]

i appreciate it, bc i never caught on till now.

[@blindcamel6236]

Good stuff

[@JyoHxOfficial]

Best Explanation Ever!!! Very educational & easy to understand🔥🔥🔥

[@t.d.3803]

Fun fact: with sine waves FM and PM are mathematically the same.

[@oraz.]

Where's it demonstrated they are different with non sines?

[@EdgyNumber1]

No. I'm completely lost. I get the principles of FM, effectively adding harmonics to a carrier wave but does PM strictly have to have a direct up and down motion? Surely, judging by your explanation, its just a difference in the type of waveform you are using. Sine waveform = FM, anything else waveform = PM?

[@oraz.]

They are the same. There's a lot of confusion online about naming but FM is PM.

[@ganapathyaiyappa3327]

Hey guys can we get a video on fixing emptiness in a track and how to fix low ends of the track please

[@mink8068]

well, this explanation is just wrong. it's neither the frequency nor the phase of the second oscillator that's modulating the carrier signal, it's the amplitude of the modulation which is affecting either the frequency or the phase of the carrier signal. what you considered to be the phase of the wave is actually the amplitude. if it was the frequency of the modulator that modulated the wave of the carrier, you wouldn't hear a difference in pitch when modulating with a low frequency of the modulator as it's constant unless you're actively changing it
