Modulator is a dynamic audio effect plugin that uses an LFO to generate various modulation-based effects, including flangers, phasers, and ring modulators. This flexible modulation source can be replaced by an envelope follower, allowing the plugin to respond to the incoming audio signal's amplitude and create unique, expressive modulation patterns. This approach makes Modulator suitable for adding movement and texture to a wide range of sounds.

The plugin offers an extensive selection of effects such as low, band, and high pass filters, frequency modulation, pitch shifting, chorus, gating, autopan, and modulation delays. Users can control feedback intensity, LFO depth, and offset, and choose from numerous waveform options, including 150 custom waves with smooth control. Tempo synchronization can be set to BPM or freeform, providing flexibility for rhythmic modulation aligned with the project.

Modulator also supports MIDI control, allowing pitch bend, aftertouch, and mod wheel to influence parameters for expressive performance capabilities. The LFO can be re-triggered by MIDI note on events, and all effects feature autopan functionality for stereo movement. Randomizer tools enhance creativity by generating unexpected modulation patterns, making this plugin a powerful tool for producers seeking to enrich their sound with intricate modulation effects.
