V4JB is an atmosphere and texture instrument. Pads, drones, air, fog. Very vibe, very mood.
VST3 and standalone. Stupid Systems LLC. MIT. Site: docs/. Manual: docs/MANUAL.md.
A modular additive synth: up to 512 sine partials per voice, 8 voices. A fixed spectral stage (18 spacing algorithms, shimmer, spectral noise, sub octaves) feeds 10 slots of swappable spectral modules (filters, Hype, Modulator, Random Drops, Phrase, Wave and more), then drive, chorus/phaser, delay and reverb. A morph pad blends four macro snapshots by hand, along drawn paths, or as an envelope. Design in docs/DSP_NOTES.md.
just build-debug (Projucer resave + MSBuild). just check runs the version compare test and the engine render check (tests/engine_check.cpp). JUCE is expected at %USERPROFILE%\JUCE (override with JUCE_PATH).
194 factory presets in 16 categories live in presets/*.xml (compiled in as BinaryData; list only what differs from the defaults). just check validates them with tools/check_presets.ps1. The built-in Wave page sources in presets/waves/ are synthesised by tools/make_waves.cpp; regenerate them with just waves.
just build-dist writes dist/V4JB-<version>-win-x64-vst3.zip, dist/V4JB-<version>-win-x64-standalone.zip, and dist/V4JB-<version>-win-x64.msi. The MSI lets you install the VST3, the standalone app, or both. Defaults are Common Files\VST3 and Program Files\Stupid Systems LLC\V4JB; each folder can be changed. Building the MSI needs the .NET 8 SDK.
