This is a personal fork of the original IanniX project, a graphical real-time open-source sequencer for digital art.
IanniX is a graphical open-source sequencer, based on Iannis Xenakis works, for digital art. IanniX syncs via Open Sound Control (OSC) events and curves to your real-time environment.

Getting started

1. Download the latest IanniX-…-macOS-arm64.dmg from the releases page
2. Open the DMG and drag IanniX into Applications
3. Launch it and open a score from FILES → Examples in the Inspector panel — press play
4. Toggle light/dark with the ☀ button in the toolbar; Cmd+, opens the preferences (Config tab)

That's it — no extra installs needed. To send/receive OSC, MIDI, or Syphon video, see the CONFIG tab in the Inspector.

⚠️ Platform support: this fork is developed and tested only on Apple Silicon Macs (arm64, recent macOS). The changes are not intentionally platform-specific, but Windows, Linux, and Intel Macs are untested here and may have regressed — use upstream for those platforms.

Branches

• main — stable; releases are built from here
• dev-macos-arm64 — ongoing work (Apple Silicon focus)
• pr/* — single-topic branches based on upstream master, intended for upstream pull requests

Changes in this fork

Build / platform

• Updated for Apple Silicon (arm64): builds with Homebrew Qt 5.15 on current macOS
• Syphon.framework built from source for arm64 and vendored in frameworks/
• Syphon client ported to the modern SyphonOpenGLClient API (enabling Syphon-In crashed with the legacy API)
• Hardened-runtime codesigning + notarization script: Tools/build-macos.sh
• Restored icons/IanniX.qrc (accidentally removed by an over-broad .gitignore)

Content & files

• Bundled Examples and Patches are copied into ~/Documents/IanniX at launch (missing files only — edits are preserved; delete a file to restore the original). Saving into the signed app bundle would break its code signature
• File browser shows one coherent tree (your Documents/IanniX folder); right-click any file or folder to reveal it in Finder
• The accent color is configurable: INFOS → RESOURCES → COLORS → gui_accent

UI / theming

• Coherent dark and light themes for the whole interface (toolbar, inspector, transport, helper, script editor), switched live with the sun toolbar button — the toggle previously only changed the score canvas colors
• Theme engine in misc/uitheme.cpp: one parameterized stylesheet + per-theme palette applied app-wide (Fusion base style). Do not add color-bearing stylesheets to .ui files — widget-level stylesheets block app-stylesheet updates on theme switches
• Configurable interface accent color (gui_accent in INFOS → RESOURCES → COLORS, default muted steel blue); a RESTORE DEFAULT COLORS button resets the palette
• Script editor: dark/light syntax color schemes, theme-following help pane, line-number gutter no longer collides with the scrollbar
• Transport: playback rate as a compact number box next to the clock
• Keyboard shortcuts: Cmd+0 resets the view to 2D (object editing is disabled while the camera is rotated); Cmd+Shift+C adds a cursor; Cmd+, opens Preferences (Config tab), revealing the Inspector if it was closed

Stability

• Fixed a crash (use-after-free) when opening scores after the file browser refreshed itself
• The file browser recovers automatically if the first launch races the macOS Documents-folder permission prompt

Using Syphon

• Out (CONFIG → SOFTWARE → Enable Syphon Out): publishes the score render as a Syphon server for any client (MadMapper, OBS, VDMX…)
• In (Enable Syphon In): registers the first available Syphon source as a live texture named syphon. Show it on a trigger with run("settexture <id> syphon"); from the script editor (or the equivalent message over OSC)

Build IanniX

macOS (Apple Silicon)

• brew install qt@5

• Xcode with the Metal toolchain (xcodebuild -downloadComponent MetalToolchain) — only needed to rebuild Syphon

• Syphon.framework is vendored in frameworks/ (built from https://github.com/Syphon/Syphon-Framework for arm64+x86_64)

• Build + sign + notarize + DMG: Tools/build-macos.sh (requires a Developer ID certificate and a notarytool keychain profile)

• Or manually:

    mkdir build && cd build
    /opt/homebrew/opt/qt@5/bin/qmake ../IanniX.pro CONFIG+=sdk_no_version_check
    make -j8
    /opt/homebrew/opt/qt@5/bin/macdeployqt IanniX.app
    codesign --force --deep -s - IanniX.app   # ad-hoc; required on Apple Silicon
  

  Note: after a code change, always delete build/IanniX.app before re-running make — relinking into an already-deployed bundle mixes two copies of Qt and the app aborts at launch.

• If you want to build IanniX with Kinect support, you'll need libfreenect (http://openkinect.org/wiki/Getting_Started)

Other platforms

• Download & install Qt5 for your platform (QtCreator included)
• Open IanniX.pro and build/run!
• Linux: install Qt via your package manager (Qt5 development + OpenGL packages) or build it from source
