Low Frequency Oscillators
Sequential
Loop: Off, On—When on, the Delay, Attack, and Decay segments of
the envelope repeat. Sustain still affects the level at which the Decay
segment ends, but instead of sustaining at a xed level while a key is
held down, Delay, Attack, and Decay loop until the key is released. (The
Release segment begins when the key is released, just as it does when
Repeat is off.)
Low Frequency Oscillators
The three LFOs are special-purpose oscillators that produce a frequency
that is typically below the range of human hearing (although these can
actually extend into the audio range if set to their maximum frequency).
The LFOs are typically used for periodic modulation such as vibrato
(periodic pitch modulation) and tremolo (periodic amplitude modula-
tion). They can also be used as modulation sources for any of the many
modulatable parameters in the Pro 3.
The LFOs produce a variety of waveshapes, including triangle, sawtooth,
reverse sawtooth, square, and s&h (sample & hold/random). Though
most often used for low-frequency modulation, the Pro 3 LFOs can actually
function at speeds that extend into the audible range for extreme effects.
