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


/usr/bin/gsequencer [--help] [--version] [--single-thread] [--no-builtin-theme] [--filename file]


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 and Core-Audio.
