       gsequencer - Advanced Gtk+ Sequencer is an audio sequencer and composition editor

SYNOPSIS

       /usr/bin/gsequencer [--help] [--version] [--no-builtin-theme] [--non-unique] [--menu-bar]
                           [--filename file] [--no-config]

DESCRIPTION

       Advanced GTK+ Sequencer is intended to use for music composition. It features a piano
       roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output
       panel. It’s designed to be highly configurable. You may add effects to its effect chain;
       and add or remove audio channels/pads. You may set up a fully functional network of
       engines, thus there is a link editor for linking audio lines.

       As version 1.0.0 it supports LADSPA, DSSI and Lv2 plugin format. And provides the ability
       to export to WAV, FLAC and OGG audio files. It can run on various soundcard backends
       including ALSA, OSS4, JACK Audio Connection Kit, Pulseaudio Core-Audio, Audio-Unit and
       WASAPI.

       The binary looks for a configuration file in $HOME/.gsequencer/ags.conf.
