scttr – free collision-based arpeggiator on iOS
scttr is a collision-based arpeggiator. Placing pulse emitters in a 2D plane enables you to intuitively create and manipulate rhythmic structures, ranging from simple patterns to polyrhythmic mayhem. Subtle parameter changes can result in startling, sometimes unpredictable results, while always maintaining sonic coherence.
It was designed as a creative software instrument/sound generator for live performances and improvisational modular setups.
The PRO version will feature MIDI support, control over sound parameters and advanced particle control parameters.
