Coil vs Recursion by folina

Coil brings the character of spring reverb into a compact, playable pedal. TWO TANKS Choose LONG for spacious, wobbling tails or SHORT for a tighter, brighter response. TWO ENGINES A uses physical spring modeling. B offers a lower-CPU vintage spring sound. Both follow the TANK switch. KICK THE TANK Tap the pedal body to strike the physical springs. You can also trigger Kick from your host, MIDI CC 83, or MIDI notes; velocity controls strike strength. THREE KNOBS DWELL sets decay, TONE shapes brightness and high-frequency damping, and MIX blends your dry signal with the reverb. CLEAN OR AMP Use the dedicated CLEAN / AMP switch to add the built-in amp stage. The lamp and artwork show the amp state. PLAY YOUR WAY Use Coil as an AUv3 audio effect in a compatible host or as a standalone app with an audio interface. The MUTED/LIVE control provides quick access to input muting. The in-app scroll guide explains controls and MIDI mappings. One purchase for Mac, iPad and iPhone.

Recursion is a delay and feedback effect built around inherited mutation. In a conventional delay, a sound repeats. In Recursion, it evolves. Each generation passes through a changing recursive system before becoming the source for the next. Timing drifts. Memories smear together. Sudden tears disturb the signal. Those disturbances are then inherited by everything that follows. The result can move from subtle animated echoes and strange doubling to deteriorating rhythmic patterns, unstable ambient spaces, and dense halls of increasingly distant memories. Seven controls keep the process immediate. Memory determines the spacing between generations. Recursion determines how deep the family tree grows. Decay determines how long those generations survive. Smear, Drift, and Tear determine how faithfully—or badly—the signal remembers its past. Recursion isn't designed to be a perfectly behaved delay. It's designed to remember. Incorrectly. Features: Self-mutating recursive delay and feedback processing Each generation inherits changes from the generation before it Independent control over recursive depth, memory spacing, and decay time Continuous bounded drift and instability Smearing that transforms distinct echoes into evolving washes Tear events introduce abrupt mutations into the recursive history From subtle animated echoes to deeply unstable feedback structures Designed for drums, synths, guitars, vocals, sound design, and ambient processing. -------------------------------------------------------------------------------------- Behavior Note: Recursion is intentionally less predictable than a conventional delay. At high Mix settings, more of the immediate dry attack is replaced by the delayed recursive signal. Short sounds may therefore seem quieter as Mix approaches fully wet. Around 50% Mix is recommended when you want to preserve the original attack. Recursive processing can also produce occasional abrupt transient or crackle-like textures as generations mutate and interact, particularly with sustained material, aggressive settings, or parameter movement. These behaviors are part of Recursion's unstable character.
