Tremolo

(1) A periodic change in amplitude, usually controlled by an LFO, with a periodicity of less than 20Hz. Compare with vibrato.

(2) A MIDI Controller Change message which is assigned to the parameter in a synthesizer which alters the depth of the effect described in tremolo. More recently this message has been reassigned as one of the five generalized Effects Depth messages. See effects control.

(3) Italian for “trembling.” A rapid reiteration of one or more notes, especially on string instruments.
