PWMOD/PWM Parameters
Both VCOs provide for
display. This means that the width setting of the pulse wave set by the
knob can be varied by a modulation source. This mod has been popular for years and
has been used to re-create many well-known sounds ranging from lush string
ensembles to thick synth pads.

modulation parameters for that VCO. A VCO's pulse width is most often modulated
by an LFO, but it can easily be modulated by an envelope, the keyboard (velocity,
aftertouch or key track), the pitch bend and modulation wheels, pedals and ribbon
controller, just to name a few of the 79 possible sources in the A6. See Appendix B for
a complete list.
