Recursion by folina

Features
Read full description

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.

Give your sound a past. Reelmoire is a hands-on tape sound studio for iPhone, iPad, and Mac. Import an audio file, choose from six machine profiles—studio reels, cassette decks, and compact recorders—and dial in anything from gentle warmth to worn, unstable texture. SHAPE THE SOUND • Add saturation, wow and flutter, head bump, hiss, dropouts, and crackle. • Play and loop your track, then compare the original with the processed sound. • Fine-tune the stereo image and save your favorite settings as presets. TAKE IT FURTHER • Export finished audio as WAV, M4A, AIFF, or CAF. • Transcribe audio into MIDI notes, including chords and overlapping parts. • Import MIDI to shape note timing, pitch, and velocity, with original/processed preview. MAKE MUSIC IN YOUR HOST Use three AUv3 plug-ins in compatible music apps: a tape audio effect, a MIDI processor, and a polyphonic instrument. Reelmoire's tape character and tactile controls follow you into your session. Audio-to-MIDI results depend on the source and may need editing. MIDI does not retain the original timbre or tape effects.
