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.

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.

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

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?

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

2:02 almost sounded like on sight by ye

[LostStylus]

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

[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?

[DeiNostri]

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

[Metli]

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

My favourite PWM is that of the MS-10.

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

[PakBudiTarigan]

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

Sounds like a Kanye West song from YEEZUS
