more this control is turned up, the greater will the increase and
decrease in the brightness of each note. Controls (17) and (19) have
an additive effect on the cutoff frequency.

You will hear the brightness of the note increase sharply at first,
and then more gradually as the attack time increases.
4. The DECAY TIME control (21) determines the duration of the second
segment of the contour, the fall from the initial peak to the sustain
level. The range of this control is about the same as that of the
previous control.
