Quick pulse-width question

[Blank]

There is no pulse width with saw waves...the only way to be able to get a pulse width modulation would be to mix a saw with a square...i have noticed tho that if u turn the shape knob half way or more towards square u can modulate the pulse width...which would give u somewhat of the effect u r looking for...but from what i know u cant modify saw waves like that...the only thing similar is frequency/pitch change...that shrinks and grows the cycle of the wave form...the deeper the pitch the longer the wave cycle and the higher the shorter the cycle...but just look at a square wave vs a saw...and u will notice that it is not possible...the saw does not have all the characteristics of the square for it to be able to do it...

peace
