qsynth(1) General Commands Manual qsynth(1) NAME Qsynth - A fluidsynth Qt GUI Interface SYNOPSIS qsynth [options] [soundfonts] [midifiles] DESCRIPTION This manual page documents briefly the qsynth command-line options. Qsynth is a fluidsynth GUI front-end application written in C++ around the Qt framework using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynths but for the moment it wraps the excellent Flu- idSynth. FluidSynth is a command line software synthesiser based on the Soundfont specification.
