Random, also known as “sample and hold,” generates a series of random
values, each held for the duration of one cycle.
Triangle is bipolar. That is, it is positive for half its cycle and negative for the
other half. That makes it possible to generate a natural-sounding vibrato that
goes alternately sharp and flat in equal amounts on either side of a center
frequency. The other wave shapes and Random generate only positive values.
However, any of the LFOs can be inverted by specifying negative

values (e.g. -127, -64, etc.) in the modulation matrix.
