A square waveform has exactly the same width, up and down but
a Pulse Width waveform has different widths. The ratio of upper
width to lower is called pulse width, 0 to 100 are valid for setting
the pulse width. Depending on the set pulse width value, the
harmonic content of the sound changes greatly.

@Velocity Range
This sets the senitivity of the velocity that controls the pulse
width from —7 to +7. With ”—" values, the pulse width becomes
