LFOs
The one exception to this is the Guitar waveform, which is designed to emulate bending a string on a guitar–so that the
pitch only goes up, and not down. Because of this, the waveform is centered on 50, and not on 0. Of course, you can
always use a negative Offset to shift it back down below 0 again!
Offset affects the signal after the Shape function, as shown below:
LFO Signal Flow
Waveform
Curve
(CURVE)
[–100...+100]
Curve adds curvature to the basic waveform. As you can see in the graphic below, this can make the waveforms either
more rounded or more extreme. It can also be useful to emphasize certain value ranges, and deemphasize others.
For example, let's say that you are using a triangle LFO to modulate filter cutoff. If Curve emphasizes the high value
range, the filter will spend more time at the higher frequencies. If it emphasizes the low range, the filter will spend more
time at the lower frequencies.
LFO Curve
+100

–100
Curve = 0 (original waveform)
Curve = +100
Curve = -100
Note: Curve does not affect the Square and Random 3 waveforms, since their values are always either +100 or -100.
Fade
[0.0000...5.000 sec]
The LFO can fade in gradually, instead of starting immediately at full strength. This sets the time from note-on until
the LFO reaches maximum amplitude.
