How to set Pulse Width percentage on Sub 37?

[drossi]

Greetings. I'm working through Welsh's Cookbook and I can't for the life of me figure out how to set Pulse Width from 0% to 50% or 100%. I understand the rightmost setting on the sub 37's oscillator wave is Pulse, but where do I set the width of the pulse?

Thanks

If you look carefully at the oscillator wave knob, notice the markings at about the 2:00 position look like a square wave, and the markings at the far-clockwise (5:00) position look like a pulse wave. At the square wave mark, the oscillator is putting out a square wave with a pulse width of 50%. As you turn the knob clockwise from that position, the pulses get narrower and narrower, until at the far clockwise position, the pulse width is probably around 10% or so.

So to answer your question: to set the pulse width, set the oscillator wave knob somewhere between the square wave and pulse wave markings.

And if a patch calls for modulating the pulse width with, say, an LFO, they you would modulate the oscillator wave setting, adjusting the modulating signal and the wave knob setting so that it varies between the square and pulse wave settings.

Hope this helps.

P.S. If you have an oscilloscope or a DAW plugin that can show waveforms from external inputs, it's very instructive to watch the wave shape change as the oscillator wave knob is turned.

Now I get it... Thanks!
