JJazzLab is a Midi-based application dedicated to backing tracks generation. You type in chord symbols, select a rhythm (style), then the application generates a complete backing track with drums, bass, guitar, piano, strings, etc.
The objective is to generate intelligent and interesting backing tracks, i.e tracks which are:

- realistic
- non-boring (with variations)
- easily customizable, even for complex songs

Buzztrax aims to be a music studio that allows one to compose songs using only a computer with a soundcard. If you’ve used tracker programs like FastTracker, Impulse Tracker, or the original AMIGA SoundTracker, that will give you an idea of how one can sequence music in Buzztrax.

The Buzztrax editor uses a similar concept, where a song consists of a sequence with tracks and in each track one uses patterns with events (musical notes and control changes). In contrast to other Tracker programs, tracks are not simply sample players: a user can make a song using an arrangement of virtual audio plugins that are linked together to create different effects. Each of these machines can be controlled real-time or via patterns in the sequencer.

Anvil Studio™ is a free Windows 11, 10 / 8.x / 7 program designed for people who want to:

This software allows “scratching” on digitally sampled audio data (*.wav, *.au, *.ogg, *.mp3, etc.) the way hip hop DJs scratch on vinyl records. It features multiple turntables, realtime effects (built-in as well as LADSPA plugin effects), a sequencer and MIDI interface – all accessible through an easy-to-use gtk+ GUI. This software is designed to run under Linux, FreeBSD and the like.
SunVox is a small, fast and powerful music sequencer with modular synthesizers. This application is addressed at all those who want to compose music everywhere they go.
Built-in synthesizers: FM; Generator; Sampler (supported formats: WAV, XI); SpectraVoice (FFT-based synth for analog-like pads); Kicker; Stereo Delay; Distortion; Echo; Filter; Vocal Filter; Flanger; LFO; Loop; Reverb.

CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single “instrument,” allowing for even more octaves without sampling artifacts.
Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.
CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
AUBE is a system for sound generation and processing. You can process audio on the fly by setting up arbitrary configurations of sound generators, sequencers and effects modules, through which sound is played, filtered, and recorded.
“Sekaiju” is free, open source MIDI sequencer / editor software for creating and editing MIDI data. You can record MIDI keyboard or synthesizer playing to the computer, and you can compose music to play with your MIDI modules or synthesizers. Since it allows editing of all kinds of events, and has an unlimited undo and redo feature, Sekaiju can also be used as a powerful MIDI editor. A real-time input which can input each MIDI channel messages into separate tracks at the same time is a popular feature .

Drumstick MIDI Monitor is a MIDI monitor for Linux using ALSA sequencer and Qt5 user interface.

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, add or remove audio channels/pads.
You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines.
In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that’s why you need at least a preemptible kernel.

SeekMIDI is a simple multi-channel MIDI sequencer for quick song creation.
