LOW FREQUENCY OSCILLATORS (LFOs)
A Low Frequency Oscillator is simply a
wave which repeats at a slow rate. Proteus
FX has two multi-wave LFOs for each of
its 32 channels. The LFO waveforms are:
Triangle, Sine, Square, Sawtooth, and
Random, which is a random “sample and
hold” type of wave.
By examining the diagram of the LFO
waveforms, you can see how the LFO will
affect a modulation destination. Suppose
we are modulating the pitch of an instru-
ment. The sine wave looks smooth, and
will smoothly change the pitch. The
square wave changes abruptly, and will
abruptly change the pitch from one pitch
to another. The sawtooth wave smoothly
decreases, then abruptly changes back up.
The sound’s pitch will follow the same
course. Controlling the pitch of an
instrument is an easy way to hear the
effects of the LFO waves.
If the key is released during the Hold (H) phase, the Release (R) phase begins.
