What is patching?

Build with blocks, not code.

plugdata lets you create and manipulate audio systems using visual elements rather than writing code. Think of it as building with virtual blocks: drop them onto a canvas, connect them with cables, and hear the result instantly.

It's a friendly, intuitive way to experiment with sound and programming, whether you're designing a synth, prototyping an effect, or teaching the fundamentals of digital audio.

Many, many objects

Batteries included: ELSE, Cyclone and Gem in the box.

plugdata ships with the ELSE library for high-level abstractions on top of Pure Data, and the Cyclone library so Max users feel right at home.

Run your patches anywhere

Standalone app, plugin in your DAW, or embedded hardware.

With Heavy/hvcc integration, full plugin support, and cross-platform builds, your patches are going places.

target / standalone

A native desktop app

Open plugdata, create a patch, and run it as a regular desktop application on macOS, Windows, Linux.

target / mobile

An iOS app

plugdata is available as a native iOS app for iPad or iPhone, directly in the App Store

target / plugin

Drop it into your DAW

Load the same patch as a VST3, AU, CLAP or LV2 plugin. Mix it with other plugins and automate it with MIDI like any other instrument.

target / hardware

Compile to embedded

Use the built-in Heavy/hvcc toolchain to export C/C++ code, flash it to an Electro-Smith Daisy, or export real audio plugins.

Who it's for

A tool for classrooms and stages alike.

plugdata for education

From high schools to universities, plugdata has found its place in classrooms and workshops, providing a simple yet powerful environment to learn the fundamentals of programming and explore the depths of audio creation.

plugdata for artists

For artists pushing the boundaries of sonic expression, plugdata offers limitless possibilities. Craft unique soundscapes, experiment with synthesis, or weave it into your live effects chain. Bring your artistic vision to life.

Vanilla compatible

Built directly on pd-vanilla.

plugdata is based directly on pd-vanilla, with minimal modifications to the original source. Your Pure Data patches open in plugdata, and your plugdata patches open in Pure Data, and your skills carry over either way.

Reads and writes the standard .pd patch format
Same runtime behaviour as upstream Pure Data
Everything you learn here transfers to vanilla Pd
All plugdata's objects objects are available in vanilla Pd through the ELSE, Cyclone and Gem externals
