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.

  • 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!
