FAQ
What is tremolo?
A steady rise and fall in volume that adds a pulsing, rhythmic motion.
How is it different from Vibrato?
Tremolo pulses the volume up and down, while Vibrato wobbles the pitch — use tremolo for a rhythmic, throbbing motion.
What does the depth control?
A light setting adds gentle movement, while a deeper one turns the pulse into a clear, hypnotic throb.

What the tremolo effect does
It moves the volume up and down at a steady rate, adding a smooth, pulsing rhythm to the sound. The motion is felt more than heard as a change in tone.
Subtle motion or deep pulse
A light setting adds gentle movement and life. A deeper one turns the pulse into a clear, hypnotic throb for retro and atmospheric moods.
Tips
- Sustained sounds and pads show the pulse most clearly.
