Qsynth 0.3.4 released!

Howdy! Simple as it could be,

Qsynth 0.3.4 released!


Qsynth is a fluidsynth GUI front-end application written in C++ around the Qt4 toolkit using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynth but for the moment it wraps the excellent FluidSynth. FluidSynth is a command line software synthesiser based on the Soundfont specification.


Project page:



Qsynth is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.


  • Command line option parsing has been slightly refactored to allow custom override through extraordinary fluidsynth option settings (eg. -o name=value; fixes bug #2781579).
  • Main form layout has been given a little bit more slack space, just to accommodate some longer text label translations (eg. German).
  • Converted obsolete QMessageBox forms to standard buttons.
  • Saved channel presets are now effectively loaded on engine startup.
  • Russian translation added (thanks to Alexandre Prokoudine).
  • Grayed/disabled palette color group fix for dark color themes.
  • Qt Software logo update.
  • Fait-divers: desktop menu file touched to openSUSE conventions.
  • Slight optimizations to the output peak meters refresh rate.
  • MIDI and audio device names are now user selectable options through respective drop-down lists on each engine setup dialog.
  • New knob style: Skulpture.

Cheers && Enjoy!


Wow, we waited until it released. I need it very much as this open-source software must be the best. Change log has many functions, thanks very much for it, they all very useful and required. It will be hightly esteemed among people.

Pleased to have the change to the main form layout. Many times required the longer text label translations. I am sure all the updates are a great improvement as well.

I hope I can expand my business enough to require the Russian Translation! Oh and the new Knob style so important!!!
