dIanniX

A modernized fork of IanniX with enhanced MIDI support and PipeWire compatibility.

WARNING: This fork is currently under active development and not ready for production use. MIDI configuration with PipeWire may require additional system setup.

About

IanniX is a graphical open-source sequencer based on Iannis Xenakis works for digital art. This fork (dIanniX) extends the original project with modern MIDI infrastructure and improved Linux audio integration.

Changes from Original IanniX

MIDI System Modernization

• Updated RtMidi library from 2012 version to 6.0.0
• Added ALSA MIDI API support for PipeWire compatibility
• MIDI virtual ports now work correctly with PipeWire-based DAWs (Bitwig Studio, Reaper, etc.)
• Added JACK MIDI API as fallback option
• Fixed MIDI note octave calculation (C4 now correctly maps to MIDI note 60)

User Interface Improvements

• Added comprehensive MIDI trigger settings in Inspector panel
  • MIDI channel selector (1-16 channels)
  • Note picker with full range (C-1 to G9, notes 0-127)
  • Velocity control (1-127)
  • Duration control (10-10000 ms)
  • Selective parameter application via checkboxes
• Added Delete key shortcut for removing selected objects
• Reduced excessive debug output for cleaner console

Build System

• Added CMakeLists.txt for modern CMake builds
• Organized build artifacts into build/ directory
• Created build.sh helper script with clean target
• Updated .gitignore for proper version control

Build Instructions

Requirements

• Qt5 development libraries
• ALSA development libraries (libasound2-dev)
• JACK development libraries (libjack-jackd2-dev, optional)

Linux (qmake)

./build.sh

Linux (CMake)

./build.sh cmake

Clean build artifacts

./build.sh clean

Manual build with qmake

qmake IanniX.pro
make -j$(nproc)

Manual build with CMake

mkdir build && cd build
cmake ..
make -j$(nproc)

PipeWire Configuration

This fork uses ALSA MIDI API which provides full compatibility with PipeWire. When IanniX starts, it creates two virtual MIDI ports: "From IanniX" (output) and "To IanniX" (input). These ports are visible to all ALSA/PipeWire-compatible applications.

To verify MIDI ports are created:

aconnect -l

You can then connect these ports to your DAW or other MIDI applications using your DAW's MIDI routing panel, qpwgraph, or similar tools.
