Undulator

Undulator by Eventide is a modulated tremolo effect with roots in the legendary H3000 processor. It pairs rhythmic amplitude and frequency modulation with detuned echoes and feedback, letting you turn short sounds into evolving pads, tempo-synced chops, or dreamy, time-lapsing textures. Use it to add movement to strings, pads, guitars, keys, and vocals, or to give sustained notes rhythmic shape. The Ribbon macro lets you morph the effect in real time via MIDI mod wheel, while Sync, Tap, and Slow/Fast modes keep the tremolo locked to your track. With adjustable mix, spread, and secondary LFO, Undulator is a creative tool for producers seeking playable, ethereal motion in their DAW.
