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 repre-

sents 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. The

effect of the Slew Rate control is most obviously heard on
