Happenstance controls

A musical decision engine, not preset roulette.

Start playback and let Happenstance hear enough material to understand the phrase. Set SAFE/WILD, then press MAKE IT HAPPEN. Use Again to ask for another interpretation, Keep to preserve one you like, and Undo when the accident went too far.

REARRANGERhythm-aware resequencing with smoothed boundaries.
GHOSTLeaves rhythmic and spectral traces while opening space around the source.
NEGATIVE SPACECreates intentional gaps and contrast rather than simply adding more sound.
CLOUD + SHIMMERMoves toward diffuse atmosphere and brighter, luminous transformations.
PHRASE MEMORIES A–DCapture useful phrases, recall them, replace them and drag WAV material back to your DAW.
three ways in

controlled unpredictability.

SAFE

Use a lower Wild value on drums or material where groove and transient definition must remain recognisable.

EXPLORE

Move toward the centre, generate several accidents, then Keep the one whose rhythm or space suggests a new direction.

WILD

Push toward the far end when the source is raw material rather than something you need to preserve.
