 Didactic Pattern Visualizer (DPV) is an easy way to visualize sound patterns from Tidal Cycles. It was created by the artist and creative technologist Iván Abreu "...to study the potential and complexity of the syntax of the pattern system for sequencing Tidal Cycles sounds." It utilizes the open source visualization program *[Processing](https://processing.org/)* to provide a scrolling grid where colored shapes appear in rhythm reflecting the flow of Tidal events (notes).
