Pd-l2ork

Purr Data is a graphical data‑flow programming environment built on the Pd‑l2ork fork of Miller Puckette’s Pure Data. It provides a real‑time interactive platform for creating computer music and multimedia applications, supporting the same core engine as classic Pd while adding a modern JavaScript‑based user interface powered by nw.js. The software runs on Linux, macOS and Windows and includes a large set of bundled third‑party externals and a help browser that accesses documentation in the PDDP format.

The environment targets musicians, sound designers, visual artists and developers who need a visual programming tool for audio synthesis, signal processing, and multimedia integration without relying on proprietary software. Its cross‑platform compatibility and improved SVG graphics make it suitable for projects that must operate on multiple operating systems.

Purr Data distinguishes itself by offering a refreshed GUI, extensive pre‑built packages for major desktop platforms, and a dedicated mailing list for community support. It remains open‑source and stable, providing a ready‑to‑use alternative to commercial visual programming environments.
