Bent Spool vs Auris

Bent Spool is a creative effect that can transform simple musical parts into unexpected rhythms and melodies, played live or as an effect in your favorite host app. Shape a tremolo pulse, turn a note into a run of pitched repeats, or build a moving layer from fragments of what you just played. Drive the input with built-in overdrive or fuzz, add a core effect, then finally layer in vintage analog tape effects. THREE MODES TREM: a pulsing volume effect, from a rounded sine through triangle and sawtooth to a hard square gate. Syncs to your host's tempo or runs free. REPEAT: up to 64 pitched copies with their own decay and feedback, across five pitch stations from two octaves down to two octaves up. LOOPS: up to six overlapping fragments of your recent audio, spread across pitch, direction, read position and the stereo field. CHARACTER CHAOS adds movement that suits each mode: octave jumps in REPEAT, held or stalled pulses in TREM, wandering reversals and pitch drift in LOOPS. WEAR adds tape wear, magnetic saturation and digital crush after the active mode. At the input, OD is a softer clip; FUZZ is a harder distortion that sputters as it decays. PRESETS 48 factory presets: 10 TREM, 15 REPEAT, 15 LOOPS and an 8-preset Fuzz Tremolo pack. Unlock to save your own. FREE TO TRY TREM plays in full on the OD voice with ten presets. No time limit, no interruptions. A single $9.99 in-app purchase unlocks REPEAT, LOOPS, FUZZ, the rest of the presets and preset saving. No subscription. Runs as a standalone app or as an AUv3 effect in AUM, Loopy Pro and other AUv3 hosts, on iPhone and iPad.
