Implemented JUCE-based VST3 plugin and standalone executable - Core audio engine: Sample playback, pitch-shifting, velocity-sensitive ADSR - 3-band parametric EQ (250Hz, 1kHz, 4kHz) with ±12dB gain - 4 filter types (lowpass, highpass, bandpass, notch) with adjustable Q - Recording system with MIDI playback scheduling and WAV export - Round-robin sample support for natural instrument articulation - Full UI with knobs, sliders, combo boxes, and file choosers - Sample manager with proper RAII memory management - Build scripts for Windows (MSVC) and macOS (Xcode universal binaries) - Comprehensive documentation (installation, build, quickstart guides) - Type-safe implementation using std::unique_ptr and JUCE framework - Cross-platform packaging system for easy distribution Key Components: - AudioEngine: Polyphonic voice management, DSP processing pipeline - ADSREnvelope: Linear ramp state machine with per-voice tracking - FilterProcessor: IIR biquad implementations for 4 filter types - EQProcessor: 3-band parametric EQ using cascaded biquad filters - Recorder: Event-based MIDI recording with offline WAV rendering - SampleManager: Type-safe WAV loading with round-robin sample mapping - PluginEditor: Complete UI with all parameter controls and file I/O - StandaloneApp: Full desktop application using JUCE framework Fixes code violations: - Replaced unsafe void pointer with typed container - Fixed timer lifecycle issues with proper inheritance - Implemented all declared methods - Added complete WAV export with offline rendering --- vst3-plugin/BUILD.md | 403 +++++++++++++++++++++++++ vst3-plugin/CMakeLists.txt | 106 +++++++ vst3-plugin/INSTALL_Windows.md | 223 ++++++++++++++ vst3-plugin/INSTALL_macOS.md | 256 ++++++++++++++++ vst3-plugin/LICENSE | 65 ++++ vst3-plugin/QUICKSTART.md | 123 ++++++++ vst3-plugin/README.md | 384 +++++++++++++++++++++++ vst3-plugin/build-mac.sh | 22 ++ vst3-plugin/build-win.bat | 20 ++ vst3-plugin/package.sh | 86 ++++++ vst3-plugin/source/ADSREnvelope.cpp | 106 +++++++ vst3-plugin/source/ADSREnvelope.h | 41 +++ vst3-plugin/source/AudioEngine.cpp | 162 ++++++++++ vst3-plugin/source/AudioEngine.h | 74 +++++ vst3-plugin/source/EQProcessor.cpp | 91 ++++++ vst3-plugin/source/EQProcessor.h | 29 ++ vst3-plugin/source/FilterProcessor.cpp | 102 +++++++ vst3-plugin/source/FilterProcessor.h | 28 ++ vst3-plugin/source/PluginEditor.cpp | 392 ++++++++++++++++++++++++ vst3-plugin/source/PluginEditor.h | 81 +++++ vst3-plugin/source/PluginProcessor.cpp | 177 +++++++++++ vst3-plugin/source/PluginProcessor.h | 74 +++++ vst3-plugin/source/Recorder.cpp | 239 +++++++++++++++ vst3-plugin/source/Recorder.h | 58 ++++ vst3-plugin/source/SampleManager.cpp | 38 +++ vst3-plugin/source/SampleManager.h | 21 ++ vst3-plugin/source/StandaloneApp.cpp | 2 + vst3-plugin/source/StandaloneApp.h | 70 +++++ 28 files changed, 3473 insertions(+) create mode 100644 vst3-plugin/BUILD.md create mode 100644 vst3-plugin/CMakeLists.txt create mode 100644 vst3-plugin/INSTALL_Windows.md create mode 100644 vst3-plugin/INSTALL_macOS.md create mode 100644 vst3-plugin/LICENSE create mode 100644 vst3-plugin/QUICKSTART.md create mode 100644 vst3-plugin/README.md create mode 100644 vst3-plugin/build-mac.sh create mode 100644 vst3-plugin/build-win.bat create mode 100644 vst3-plugin/package.sh create mode 100644 vst3-plugin/source/ADSREnvelope.cpp create mode 100644 vst3-plugin/source/ADSREnvelope.h create mode 100644 vst3-plugin/source/AudioEngine.cpp create mode 100644 vst3-plugin/source/AudioEngine.h create mode 100644 vst3-plugin/source/EQProcessor.cpp create mode 100644 vst3-plugin/source/EQProcessor.h create mode 100644 vst3-plugin/source/FilterProcessor.cpp create mode 100644 vst3-plugin/source/FilterProcessor.h create mode 100644 vst3-plugin/source/PluginEditor.cpp create mode 100644 vst3-plugin/source/PluginEditor.h create mode 100644 vst3-plugin/source/PluginProcessor.cpp create mode 100644 vst3-plugin/source/PluginProcessor.h create mode 100644 vst3-plugin/source/Recorder.cpp create mode 100644 vst3-plugin/source/Recorder.h create mode 100644 vst3-plugin/source/SampleManager.cpp create mode 100644 vst3-plugin/source/SampleManager.h create mode 100644 vst3-plugin/source/StandaloneApp.cpp create mode 100644 vst3-plugin/source/StandaloneApp.h diff --git a/vst3-plugin/BUILD.md b/vst3-plugin/BUILD.md new file mode 100644 index 0000000..33f8d1b --- /dev/null +++ b/vst3-plugin/BUILD.md @@ -0,0 +1,403 @@ +# Building Snowflake Instrument Studio VST3 + +Complete instructions for building the VST3 plugin and standalone application. + +--- + +## 🖥️ System Requirements + +### **Windows 11** + +- **Visual Studio 2022** (Community Edition is fine) + -

b6cb2a24353cc9624a65d262d414a7dd208e1bd9 Mon Sep 17 00:00:00 2001 From: TracyLee1972 Date: Fri, 20 Mar 2026 22:02:16 +0000 Subject: [PATCH 4/6] security: Add bounds checking to ADSR envelope parameters - Set minimum sampleRate to 1kHz (prevents division by zero) - Set minimum attack/decay/release to 1ms (prevents NaN from zero values) - All timing parameters now guaranteed non-zero before division operations This prevents potential undefined behavior or NaN propagation in audio processing. --- vst3-plugin/build/CMakeCache.txt | 358 ++++++++ .../CMakeFiles/3.28.3/CMakeCXXCompiler.cmake
