the reference signal. For example, a 100 Hz tone

has harmonics at 200 Hz, 300 Hz and so on.

LFO:

An LFO or Low Frequency Oscillator is a periodic

signal source (usually below audio frequency

range) used to modulate another signal parameter.

An LFO can be used for a variety of effects

including vibrato (by modulating the pitch) and

tremolo (by modulating the volume).

Microtuning:

See Appendix A for a detailed description.

Matrix:

A signal junction where a source signal can be

patched so that it controls a destination signal. The

Octopus's Envelope Matrix is used for tasks such

as modulating a generator's amplitude by an

Envelope.

Oscillator:

A signal source that generates a waveform at a

given frequency.

Phase:

Phase defines the position of a point within a

waveform cycle. If a complete waveform cycle is

defined as having 360 degrees, then a phase shift

of 90 degrees moves the point one quarter of the

way along the waveform.

Sequencer:

A sequencer is a device that can be used to record

and play back musical control data.
