Hi,
i've read many threads in the forum but it seems like there's no ready-2-use module "PWM" for adding simply to an multi osc?! :-(
Simply add PWM to an OSC (ready-2-use module available?)
From the original SynthMaker forum (2004–2014), with its members’ names and dates.

Is this the right way?
Is it normal that every output sounds like a square then, whatever i've selected as waveform?

You can do that, but I think when you do Code OSCs, you'll get some aliasing at higher pitches. Fine for typical OSC usage & good for LFOs.
Seems you missed my thread & WIKI postings.

Hi infuzion,
i've downloaded the schema from [old link] .
Sounds good... but how can i add this simply to an multi osc?

...but you will geneate non-aliased square pulses out of everything... reading the code (casually) the input only appears in a comparison... so the output will be either 1 or -1.

Dave, simply copy & paste what you want inside the MultiOSC, move the connections from the existing Square to the new one, then add an extra In or 2 to get the PWM control to connect to the new Square. If you don't know how to do that, might be better for you to run through the tutorials... I don't want to sound mean, but simple replacement hacking is one of the basics everyone has to learn.

For some reason, my instinct says that anything outside a Sine wave will have extra harmonics, which will end up wrapping around with higher pitches at lower sampling rates. The output of the picture above is indeed only +/-1, & doesn't benefit from the bandlimiting of the "source" OSCs. I may be wrong though...

Ups... perhaps i'm totally wrong with PWM?
Does PWM only make sense with a square?
So if a saw in the multi osc is selected the PWM should be switched off because otherwise the output is no saw but a pwm'ed square?

Looks like January's the "Month of PWM":
I think it's pretty logical and everyone will agree if I state that: the more general -- W idth M odulation -- applies also to triangle, saw, whatever waveform you want, but PWM is obviously just -- P ulse W idth M odulation -- and reserved to pulse (also called square)..
PS. Rarely you can find TWM (triangle width modulation) and saw width modulation (i.e. saws are WM-able in some oberheim synths) but I've never registered any special name for other width modulations performed on different waves than pulse and triangle, but of course there are many examples of HW and SW performing those last...i.e. Vember Audio Surge does a lot of wraps n' rips on his tables, both vertically and horizontally including WM..
