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.

Note:

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, Wave Reset is

off—there is no fixed start point from which the

phase can be offset.

Slew Rate: 0...127

—Slew rate is defined as the

maximum possible rate of change of a signal.
