"plateau" portions that give the wave symmetry. This
waveform, therefore, provides sharp high-low modulation
and is commonly used to produce a "trill".
Aperiodic Waveforms
RANDOM - "Random Modulation"
This waveform outputs an irregular modulation pattern used
mostly for effects.
NOISE - "Noise Modulation"
This is also an irregular modulation signal in many respects
similar to RANDOMbui sounds like Random Modulation at
a much higher speed. As a result, using this wave gives a
noisy, harsh effect to the sound, hence the name.
The SPEED control has no effect for these two waveforms.

SAMPLE - "Sampled Modulation"
When this is selected, the LFO samples another modulation
source and uses that as its waveform. The SPEED
parameter controls how often this source is sampled (the
"sample rate"). The source to be sampled can be any of the
MATRIX-12's 27 Sources, selected with Knob #3.
