Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves. Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones. Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space. Features: - Orbital echoes, where Feedback sets how many circle you - Spin, from a gentle drift to a full whirl - Doppler pitch-bend as the orbit turns - 3D binaural imaging for headphones - Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves) - Per-echo Trail tone, tape Wobble, and Drive - Lush reverb applied to the echoes - Full 5-band EQ on the wet signal - Orbit and Ping-Pong patterns, tempo sync - 18 factory presets, plus save your own - Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more No accounts, no tracking, no data collected. Everything stays on your device.

Groove Destroyer isn't a gate, stutter, or glitch effect. Instead of chopping your audio into predictable patterns, it continuously reinterprets the groove underneath your music. Rhythms shift, accents evolve, filters dance, and movement emerges that feels alive instead of programmed. At the heart of Groove Destroyer is an intelligent groove engine that generates evolving rhythmic events while preserving the underlying pulse. Resonant filters, animated movement, saturation, and controlled instability combine to produce textures ranging from subtle motion to complete rhythmic mayhem. Use it on drums, percussion, synths, guitars, loops, vocals, or entire mixes whenever you want movement that sounds organic rather than mechanical. Whether you're adding a little instability or pushing a beat to the edge of collapse, Groove Destroyer creates grooves that never play exactly the same way twice.

Swing Introduces evolving timing offsets and rhythmic feel. Density Controls how frequently the groove engine generates new rhythmic events.

Glue Blends saturation and dynamic cohesion to keep evolving rhythms feeling musical. Mix Blends processed and dry signals.
