aveX is a free software for running and monitoring ABX listening tests. It works as a Jack (Jack Audio Connection Kit) client and is able to send test-status messages over a network for monitoring purposes. ‘A’ and ‘B’ audio files are read in pairs from a list and played in randomized order, the ‘X’ audio file is also randomized and is either ‘A’ or ‘B’ (double-blind test).
The listening test results are written after every choice in a file in text format.
The program is configured by filling in a very simple XML file.

Features:
- Cross platform support (Linux, macOS and Windows to name a few)
- SoundFont 2 support
- SoundFont 3 support (vorbis-compressed SF2)

QSynth is a fluidsynth GUI front-end application written in C++ around the Qt framework using Qt Designer.

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.
