Slew Rate:
0...127
—Slew rate is defined as the maximum possible
rate of change of a signal. The effect of the Slew Rate control is most
obviously heard on Pulse and Random, shapes that normally change
state virtually instantaneously. As Slew Rate increases, those changes are
drawn out, elongated, and the result is a sort of smoothing effect.
Slew behaves much like a low-pass filter and can be used to “round off” the
triangle wave for a more sine-like shape.
Phase:
0...127
—Used in conjunction with Wave Reset, Phase sets the
initial phase, from 0 to 360 degrees, at which the LFO wave shape starts
when keyed on. Each step represents 2.8125°, so a value of 32 equals 90°,
64 equals 180°, and so on.
Use Phase to offset the start point when Wave Reset is on. For Phase to have
any noticeable effect, Wave Reset must also be turned on for that LFO. If the LFO is
free-running—that is, with Wave Reset off—there is no fixed start point from which the
phase can be offset.
Wave Reset:
Off, On
—When off, the LFO is free running. When on,
the LFO is re-started each time a new note is played.
