ChowMatrix by Jatin Chowdhury was released and last updated in February 2026.
ChowMatrix allows users to construct unique branching delay networks, where each node (representing new delay head) can spawn children with adjustable parameters for feedback, pitch, pan, and more, creating complex, evolving delays. You can even make the branches swing in the wind, creating organic, complex modulating delays. It supports AUv3 hosting in DAWs like GarageBand or AUM, making it a fun tool for sound designers in iPad music production exploring chaotic or ambient effects.
The app’s tree-based structure encourages experimentation, with options for randomization and node management. For how to make music on iPad, it’s a unique free utility for adding depth to tracks, though the complexity may overwhelm beginners.
ChowMatrix is an innovative free effect for delay enthusiasts, enhancing mixes with its modular approach in the best iOS music apps.
