Advanced GTK+ Sequencer (AGS) 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. Further it has LADSPA, DSSI and Lv2 plugin support. 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. AGS requires a realtime kernel and ALSA support. AGS uses conditional locks to keep several threads in sync that's why you need at least a preemptable kernel.

LADSPA support has been added to version 0.4.2 as well export to WAV.

Version 0.5.x brings you first concurrent audio tree processing support.

Version 0.6.x is dedicated to accessibility. You might control GSequencer by keyboard. As you move to a note it provides you an audible feedback.

Version 0.7.x gives you the benefit of providing the libraries libags, libags-thread, libags-server, libags-audio and libgsequencer. It contains for now an automation editor. Open Sound System (OSS4) and JACK Audio Connection Kit support has been added recently. Now you may configure multiple soundcards. Since 0.7.111 there is MIDI input available. Let you record your MIDI instrument and doing live performance.

Version 0.8.x extended MIDI support to import/export SMF. A built-in envelope editor and additional editing functionality like move/crop selected notes.

Version 0.9.x added automation editor.

Version 1.0.x released implemented sticky controls.

Version 1.1.x segmented AgsNotation and AgsAutomation.

Version 1.2.x improved audio backend support and improved accessibility by using Atk+ interfaces. Migrated to segmented AgsNotation ,

Version 1.3.x migrated to segmented AgsAutomation.

Version 1.4.x AgsWave and AgsBuffer have arrived in libags_audio.so

Version 2.0.x provides new machines AgsEqualizer10, AgsSpectrometer and AgsAudiorec. Wave form manipulation and recording capabilities.

Version 2.1.x has got initial OSC content model support. The provided OSC server allows you to do remote control.

Version 2.2.x support for GCC builtin vector functions and added complex data type support.

Version 2.3.x added new machines AgsFMSynth, AgsFMSyncsynth and AgsPitchSampler. Support for WASAPI.
