Gravity Audio Lab / Gravitational delay
Event Horizon
Pull time into orbit.
A space-inspired delay where repeats stretch, diffuse and move through the stereo field. Explore gravitational time dilation, shape the feedback, and freeze the sound at the horizon.

Time with a gravitational pull
Use Mass to spread successive repeats further apart, while Orbits shapes the feedback.
Motion in the stereo field
Combine orbit modulation, width and ping-pong with Tidal diffusion to explore moving echoes.
Cross the horizon
Engage Freeze to sustain the delay. Start from one of 12 factory presets across five categories, or save your own.
Shape your orbit
From a repeat to a new dimension.
- Time & sync
- Set delay time freely or synchronize it to your host tempo.
- Orbits
- Control feedback and the persistence of your repeats.
- Mass
- Introduce time dilation: at maximum Mass, each repeat is spaced 1.5× further apart than the last.
- Redshift
- Shape the tonal character of the repeats.
- Tidal
- Add diffusion to the delay.
- Orbit rate & depth
- Shape Doppler modulation and stereo rotation.
- Width & ping-pong
- Control the stereo field and alternate echoes between channels.
- Freeze
- Hold the delay in a sustained state.
- Filters, mix & output
- Set low and high cut, balance dry and wet sound, and adjust output level.
