nyx.vfx is a multithreaded, real-time shader pipeline for creating GPU-accelerated visual effects synchronized with musical events.
Originally developed to synchronize music with video effects in DaVinci Resolve, the project evolved into a modular visual engine supporting MIDI-driven effects, parameter automation, multi-pass shader processing, and frame-accurate video export.
Highlights
- Multi-pass GPU shader pipeline
- MIDI-driven visual triggering and automation
- Dynamic VST3 parameter registration
- Frame-accurate video export
- Interactive effect design and experimentation

nyx.vtheory vst3 plugin
Interactive chord and music theory tool · VST3 · C++
nyx.vtheory is an interactive tool for exploring chord progressions and harmonic relationships without interrupting the creative process.
It provides visual chord relationships, rapid progression building, custom layouts, and chord stacking in a lightweight VST3 plugin.
Highlights
- Visual chord relationship mapping
- Rapid progression experimentation
- Custom progression creation
- Flexible layouts and chord stacking

nyx.wnd & nyx.host
Cross-platform embedded windowing and plugin UI test infrastructure · C++ · Win32 · X11
nyx.wnd on GitHub · nyx.host on GitHub
nyx.wnd is a lightweight glue library for environments where an application or plugin framework provides a native parent window but leaves management of the embedded UI to you.
It creates and manages the child window, provides event-loop and UI-thread scheduling, and stays independent of the renderer placed inside it.
nyx.host provides the other side of that boundary: a lightweight standalone host for developing and testing embedded UIs without requiring a complete VST3 plugin or DAW.

Spectral MIDI Engine Testbed
Real-time spectral analysis and audio-to-MIDI engine · C++ · FFT · MIDI
The NyxFX Spectral MIDI Engine explores the problem of extracting musically meaningful MIDI events from real-time spectral content.
Built as the signal-analysis backbone for nyx.vfx, its standalone test environment provides deterministic signal generation, FFT visualization, interchangeable mapping algorithms, and tools for developing and evaluating audio-to-MIDI strategies.
Highlights
- Real-time ring buffer and overlapping FFT processing
- Configurable windowing and FFT pipeline
- Hot-swappable spectral-to-MIDI mapping
- Harmonic Energy and Gaussian Cents mapping
- Multi-region spectral analysis
- Synthetic signal generation for deterministic testing
- Real-time FFT and MIDI visualization
