The display page parameters for every one of the six
LFOs are similar.
Shape
Sets the type of waveform generated by the corresponding
LFO.
•
The
Sine
shape is best suited for oscillator FM or pan
modulations.
•
The
Triangle
shape is perfect for smooth pitch, filter
or volume modulations.
•
The
Square
shape can be interesting for hard pan
modulations or special effects.
•
The
Saw (down)
shape can generate interesting filter
or volume changes. It creates a falling sawtooth wave.
•
The
Saw (up)
shape can generate interesting filter or
volume changes. It creates a rising sawtooth wave.
•
S&H
(Sample & Hold) samples a random value and
holds it until the next value is generated. If
Speed
is set
to
0
, a random value is generated on each new note.
