parameter
A numerical value used to control some aspect of an SFX Machine
Pro patch.
patch
A configuration of interconnected modules and associated menu
items and parameters. You can design new Patches using the Preset
Editor. Patches are also referred to as “Presets.”
phase
1. The periodically changing appearance of the moon, due to
angular rotation.
2. A fraction of a cycle of a waveform. Typically phase is measured
as an angle. A sine wave makes a positive zero-crossing at 0°
phase; hits 100% at 90° (or 1/4 cycle); makes a negative zero-
crossing at 180° (1/2 cycle); hits –100% at 270° (3/4 cycle); and
returns to zero at 360°. See “Initial Phase.”
PhaseShape
The PhaseShape process changes the shape of sine, triangle, square
and sawtooth waveforms, thus changing their timbres. PhaseShape
Modulation (Phase Mod) changes the amount of PhaseShaping over
time.
pitch
A psychoacoustic phenomenon that is closely related to but not
synonymous with frequency. Pitch is the subjective property that
lets us compare whether one sound seems “higher” or “lower” than
another.
The pitch of a sound can be ambiguous or ill-defined. What is the
pitch of a chord, a click, white noise or silence?
pitch tracker
A process that “listens” to a sound and attempts to track its pitch
contour. You may use the resulting signal to modulate another
module’s source frequency, filter cutoff, or (inverse) delay time.
polyphonic
Music in which several melodic voices are playing at once.
