Examples

This page is the curated gallery for the documented core examples. The broader examples/ tree also contains subsystem demos and platform-specific proof projects such as MPE, WebView, Three.js, SDF, Stream, Plugin Host, Audio Inspector, and iOS AUv3 examples.

Reference

These examples are polished and demonstrate best practices for building Pulp plugins.

Example	Summary	Formats
PulpGain	Stereo gain effect with input/output gain and bypass	VST3, AU v2/AUv3, CLAP, Standalone, optional AAX

Validation

These examples exist to test and validate specific subsystems of the framework.

Example	Summary	Formats
PulpTone	Polyphonic oscillator synth with MIDI input	VST3, AU v2, CLAP, Standalone
Timeline Phase 1	Audio-file, step-pattern, and multitrack graph/PDC playback through the Creative Timeline Engine	Headless, Standalone
Timeline session	Clip-launching session and a full DAW-style project: launch quantization, per-track arbitration, nested sequences with divergence, takes/comp, journaled autosave	Headless
Timeline Plugin Proof	Loadable plugin owning a Timeline session, editor-host seam, native view shell, edit intents, and canonical plugin state	CLAP
PulpEffect	Biquad filter with frequency, resonance, type, and mix	VST3, AU v2, CLAP
PulpCompressor	Sidechain compressor with multi-bus input	VST3, AU v2, CLAP
PulpDrums	Generative drum sequencer with MIDI output	CLAP

Experimental

These examples explore features that are not yet stable across all platforms.

Example	Summary	Formats

SuperConvolver	GPU convolution reverb with live IR swap — built on the GPU audio runtime	VST3, AU v2, CLAP, Standalone
Spectral Lab	N-layer GPU spectral freeze / morph cloud — built on the GPU audio runtime	VST3, AU v2, CLAP, Standalone
GPU NAM	Neural Amp Modeler (.nam) player with a GPU audio engine — now in its own repo	VST3, AU v2, CLAP, Standalone
Bendr	Pitch / formant shifter with spectral freeze and a pitched feedback delay — now in its own repo	VST3, AU v2, CLAP, Standalone

Building Examples

The CMake-backed gallery examples build as part of the standard CMake build when their platform and option gates are satisfied:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

To build a specific example target:

cmake --build build --target PulpGain_VST3
cmake --build build --target PulpTone_Standalone

Which Example Should I Start With?

Start with PulpGain. It is the simplest plugin and covers the full pipeline: Processor subclass, parameter definition, format adapters, format-specific entry points, and validation tests. Every other example builds on patterns established in PulpGain.
