What it does
Eccentric Echo puts two independent engines inside the same feedback world: the conventional Delay engine handles everything from single and dual taps to ping-pong patterns, while the Eccentricity engine captures and replays short fragments of audio for more unstable, spliced repetition - a sound-design tool for reshaping repeats as much as a conventional delay for spacing them.
Run the two engines in PARALLEL for independent delay voices sitting side by side, or SERIAL so Eccentricity's output literally becomes Delay's input - each keeps its own timing, pitch, reverse, width and feedback (extending to 150%), while shared filtering, saturation and internal reverb progressively reshape the wet signal into pitched, disintegrating trails the longer it feeds back on itself. A final ANALOG stage adds tape-style wow/flutter and saturation across the combined output.

In Action
Highlights
- Dual-engine delay + splice/replay design
- Serial or Parallel routing
- Ping-pong stereo mode in the delay leg
- Independent ±2400-cent (±2-octave) PITCH control on each engine
- Stepped 100-cent drag by default; Ctrl-click (Windows) / Cmd-click (macOS) toggles either dial to free fine-tuning, remembered per dial with the session
- In-loop saturation
- Constant-power engine blend behaviour
- Feedback up to 150%, including self-oscillating territory
- Output loudness automatically follows the input loudness at every setting, so MIX, feedback and engine moves never change the overall level
- REV plays each engine's repeats backwards, independently on the Delay and Eccentricity engines
- EXPORT MODE - 4x oversampling for higher-quality final renders
