zebra pulse width

[gentleclockdivider]

At the moment since zebra's osc are in fact wavetables and not code generated osc's , the pulse width sounds a bit strange ( applying pulse width from the osc module of course draw a square wave first ).
The only way to make it sound real is to actually draw a square ...to pulse and then applie wave scanning .....instead of using the pw on the osc module
So , will the upcoming release of zebra have some real osc's with real pw ?

But when you're adjusting the PW in PW mode, you're just summing two static sawtooth waves with varying phase offset (and with one phase inverted), which is what most synths do to create a varying pulse. This should actually be more 'realistic' than creating a square to pulse wavetable, because the wavetable is updated at a frequency slightly shy of the control frequency (AFAIK), whilst the inversion-modulation-PW is happening at the control frequency, with no wavetable animation required.

Note if you're applying PW using the inverse summing mode thingy, you need a saw as your basic wave, not a square. Maybe that's where you're going wrong?

Open a new instance, click PWM button, put LFO on phase. That's what Sendy says, in a nutshell.

There's always the negative sync trick. Set up a square wave (or any wave with a vertical transient in the middle), enable sync mode then send a negative modulation to the sync amound via the mod matrix. This sounds slightly different to my ears (kinda crisp and chompy), though it looks like regular PWM. I could explain why it produces PWM but it would probably bore everyone and take too long

Which mode? There are currently 3 forms of PWM:




Each of which sounds different. One might appeal to you more than others. And be sure to mess with the resolution knob; it can make PWM sound completely different at various values.

There's always the negative sync trick. Set up a square wave...

Slightly different would be to modulate the phase with the LFO instead of the sync tune. As we know that the phase knob has a significant timbral effect while osc sync is active. (more noticeable with small sync tune offsets)

-select square wave
-turn osc sync on and offset sync tune with gate or an "unused" maxed constant sum mods MMixer to -12

-set osc phase to 25 and modulate with LFO, positive or negative 12

Different sound... smoother and slightly more "detuned"

Apply the osc PWM effect with a saw, not a square. As mentioned this is what most synths do internally (both analog and digital) to generate PWM, and how to create the "normal" PWM sound.

[Sendy]

I quite like adding a modulated odd/even FX to a PWM patch. If you set it going at a different speed to the PWM, you get a cool, intense, constantly changing effect that still sounds like PWM.

Zebra is a good synth for doing PWM+ (i.e. taking it that one step further)

yes yes ,indeed pw is possible with a saw .( + invertedsaw )
I was trying it with a square ,
