Oscillators- Pulse Width Modulation

Pulse Width Modulation is a pleasing aural effect generated by the voltage-controlled adjustment of the width of a square wave. In this Foundation of Synthesis video, Marc demonstrates this function on several classic synthesizers. The video includes an oscilloscope, which shows you exactly what is happening when the width of the square wave output of the oscillator is changed!

Your excellent demonstration finally helped me make sense of pulse width modulation. This and detune Seem like a nice way to get some real beef out of limited resources.

[@CaidicusProductions]

These videos are really helpful. I bought a Voyager XL this year, and have pretty much no experience with physical synthesizers (or VSTs for that matter.) This means, while it's fun to play with the Voyager XL, I mostly have no idea what I'm doing with it, as I lack the basic understanding that you're teaching in these videos. I'm very grateful.

[@salexmatei]

100% understood. thanks

[@brlinrainf]

thank you now I know how does an inverter air conditioner sound like

[@timburlingame5893]

I really need an oscilloscope

[@hz6612]

thank you !

[@oooomar]

thank you sir

[@eduardooyarzun3797]

Thanks for this ;)

[@midifromhell]

What happens when you put the speed of the LFO into the audible range? Is there a new type of FM-like synthesis hiding in there, or is it more basic?

[@JohnJohnCrusher]

Thanks

[@NuisanceMan]

Pretty groovy, man.

[@Roderick_Legato]

@Nathan Reeves: Appears to be a Yamaha CS-15.

[@Metli94]

thank you! I thought the gap of pulse width modulation was a problem with my synth :D

[@NathanReevesnate808]

what was the first keyboard? the second is an arp 2600 no?

[@DeiNostri]

Is that a Yamaha CS? It almost looks like a CS-5 but im not quite sure, is it a CS-15?

[@grigoir]

It does the trick

My favourite PWM is that of the MS-10.

[@dayglo98]

+ec101dm I like the one on the Commodore 64 :p Not bad on the Korg MS2000 either.

[@PakBudiTarigan]

Does yamaha modx has feature to do this? Pls someone opinions

[@jazzer84]

I'm not that into FM synthesis (which is what MODX has along its own S+S engine called AWM2). But I think there should be some way to achieve a similar timbre through either FMx or AWM2 engines. What you are looking here is a sustractive synthesis engine, so there would be no direct correspondence but in your reference manual you should have a very deep and complete description of the synth engine and its sonic possibilities.

[@officialdjclout]

what kind of hardware is this demonstrated on. this thing looks awesome, also is this a built in oscilloscope? are there oscilloscopes like these one can buy?

[@AdamTheAd-vanc3d]

Kevin Nowacki The hardware used is a vintage Yamaha Cs 15 and an Arp 2600, Marc uses an editor to do a split screen view here with, a seperate oscillope view its not built in . However the new(ish) Korg minilogue (poly), and the (monophonic) monologue have this built in :-).

[@infacedgetout]

2:02 almost sounded like on sight by ye

[@shabbynabby6685]

myxmnatosis?

[@serfasleep]

Is that you Marc Doty?

[@LostStylus]

I don't get it, seems like it's the same as frequency
