bip is a fantastic creative tool for playing, recording and performing musical rhythmic patterns. Starting with the simple idea of a programmable generated beat, touch and hold gestures are used to select beats and patterns. Patterns of recorded beats can be mixed and matched along with a touch-strip controller for transforming beats. Choose from track templates for quickly creating tracks or spend the time importing and tweaking beats with your own samples.
