Pulse Width Modulation can be done is several ways in Dune. The easiest is probalby manually using the Mod Wheel. Set the Pulse Width knob on the GUi to around 5%, and in the MM follow the settihng in the image. Moving the MW will change the width
using an LFO is also simple, but much smoother. Set LFO1 to a sine wave, speed to around 1/4 or 1/8 (fade in to taste) In the MM follow settings in image.
you can also combine the MW and LFO...by using LFO!*MW as the source, the MW controls the AMOUNT the LFO affects the PWM
You can also use the Mod Env for PWM. Set the PW to around 90%, and use setting in the image below. Adjust the Mod Env setting to vary the effect.
You can use 2 unison voices and two LFO's at diff rates for a thicker PWM sound. Set LFO1 to 1/4 and LFO2 to 1/8, then pitch up voice 2 an octave to really hear the difference. (solo each voice to find a speed that suits) Also, when using an LFO, it sometimes sounds better if the effect slowly fades in, rather thatn being there from 'note on'
you can do a simpler similar version by using constant values to keep each voice at a set PW.

Dune - PWM TipsIs there any way to prevent that PW reach its max or min value using an LFO? I ask this because at its max or min value the pulse becomes a flat line and it doesn't sound, it's technically correct, although, but uncomfortable.
Dune - PWM Tipsyes, which is why i used those settings....place PW knob at centre (technically 50% square) and set value of LFO to no more than 49%. I keep it a bit lower, 35% cos it sounds better.

Tweak the PW knob and/or reduce the LFO amount at the MM. The described behavour was discussed in beta phase, it's technically correct, as you say and it also gives a potential for stutter and gating effects.

Dune - PWM TipsIf you keep up with this, looks like there will be more of it.

Dune - PWM TipsI could guess that, however I had an small hope. I'm not an expert programming synths but I think that other PWs I've tried doesn't get muted and you can achieve less squarishs sounds if the PW is at ~75% and it has a big modulation, like 40%-50%. I like that sound.
