Description
AI generated. Mosaic Spool is a standalone browser sample instrument for rearranging sounds into new rhythmic phrases.
Three original source recordings are generated locally from editable synthesis code. Import your own licensed mono or stereo audio, divide it into eight slices, edit their boundaries, reverse individual pads and perform using the mouse or computer keyboard.
Arrange sixteen steps with per step velocity, swing and tempo. Choke previous slices or layer up to four. Pitch and speed use resampling and therefore change both pitch and duration. Session JSON embeds PCM audio so a saved session can carry its source recording.
