FluidPatcher ~ GUI & Automation

FluidPatcher is a performance-oriented interface for FluidSynth built using wxpython to create a simple GUI that allows live editing, selecting, and playing of patches. A patch is a collection of settings such as soundfont presets for each MIDI channel, control-change/sysex messages to send when the patch is selected, and midi router or effects settings. Groups of patches are stored in banks, which are saved as human-readable and -editable YAML files. This allows a musician to easily create complex combinations of synthesizer settings ahead of time and switch between them on the fly during a performance.

Features:

  • Live playing: Play on your MIDI controller and hear the results
  • Customization: Create your own combinations of instruments/effects
  • Extendability: Use the included libraries to design your own implementations/software
