The Modulator effect adds both vibrato and tremolo to audio by modulating (varying) the frequency and amplitude.

Modulation Type

The type of waveform to use. Sine produces smoother modulation. Triangle produces more abrupt modulation.

Modulation Rate

The rate in Hz of the modulation.

Modulation Depth

The amount of frequency modulation.

Amplitude Modulation

The amount of amplitude modulation.
