JJazzLab-X is a Midi-based framework dedicated to backing tracks generation -some people talk about “play-along songs” or “auto-accompaniment applications”. 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 develop a jam buddy able to quickly generate intelligent and interesting backing tracks: realistic and non-boring backing tracks which you can easily adjust to a specific song.

SuperCollider ~ Audio Synthesis & Composition
SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It consists of:
- scsynth, a real-time audio server with hundreds of unit generators (“UGens”) for audio analysis, synthesis, and processing
- supernova, an alternative server to scsynth with support for parallel DSP on multi-core processors
- sclang, an interpreted programming language that controls the servers
- scide, an editing environment for sclang with an integrated help system
sclang comes with its own package manager, called Quarks. scsynth and supernova both support third-party plugins via C and C++ APIs.

ChordPro ~ Create Lead Sheets
In 1992 Martin Leclerc and Mario Dorion developed a simple text file format to write lead sheets, songs with lyrics and chords, and a tool to create neatly printed lead sheets out of these text files. The tool was called
www.chordpro.org/chordprochord, and the text files were calledchordfiles. It soon became a popular way to write lead sheets and many users and tools adopted this format for similar purposes. For still unknown reasons people started calling the fileschordprofiles.
The ChordPro (also known as Chord) is an ASCII text file format for transcribing songs with chords and lyrics. The format was originally used for guitar, but is used for variety of other string instruments, such as ukulele, bass guitar or mandolin. Although this format is legible as it is, there are many popular programs for displaying, transposing and printing. Files in this format often have extensions such as .crd, .chopro, .pro, .chordpro or .cho.

Chrome Music Lab ~ Interactive Music Online
What is Chrome Music Lab?
Chrome Music Lab is a website that makes learning music more accessible through fun, hands-on experiments.
What can it be used for?
Many teachers have been using Chrome Music Lab as a tool in their classrooms to explore music and its connections to science, math, art, and more. They’ve been combining it with dance and live instruments. Here’s a collection of some uses we’ve found on Twitter.
Can I use it to make my own songs?
Yes. Check out the Song Maker experiment, which lets you make and share your own songs.
Do I need to make an account?
Nope. Just open any experiment and start playing.
How were these built?
All our experiments are all built with freely accessible web technology such as Web Audio API, WebMIDI, Tone.js, and more. These tools make it easier for coders to build new interactive music experiences. You can get the open-source code to lots of these experiments here on Github.
What devices do these work on?
You can play with these experiments across devices – phones, tablets, laptops – just by opening the site on a web browser such as Chrome.

AGS ~ Advanced Gtk+ Sequencer
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.
Features:
- save or open Advanced Gtk+ Sequencer XML files with XPath support
- add or remove audio engines with adjustable audio channels and pads
- link channels with property dialog
- output panel, mixer, drum and matrix sequencer, soft synth and audio file player
- piano roll with basic notation editing supporting copy & paste
- adjustable BPM
- LADSPA, DSSI and Lv2 support
- export to WAV, FLAC, OGG and others

- automation editor
- waveform editor with copy & paste
- capture sound with AgsAudiorec machine
- MIDI instrument input
- import/export to Standard MIDI Files
- OSC content format support
- OSC server for remote control and monitoring

Polymeter ~ Compose Polymeter Based Music
Polymeter is a MIDI sequencer for music that’s in multiple prime meters (1, 2, 3, 5, 7, 11, etc.) simultaneously. Each track has its own loop length, and when the lengths differ, the tracks “slip” (or shift phase) relative to each other. The resulting interference pattern is sufficiently intricate that variations similar to the embellishments of a live performer can be generated algorithmically.
Features:
- Multitrack step sequencer for polymeter
- Each track has its own loop length
- Any number of tracks, of any length
- Full clipboard support (copy/cut/paste)
- Unlimited undo and redo for all edits
- Multiple tracks can be edited at once
- Optionally shows current position within each track
- Drag reordering of tracks
- Exports a MIDI file
- Join adjacent steps to make tied notes
- Velocity editing
- Controller tracks
- Recording of live arrangement
- Editing of arrangement on timeline
- Inter-track modulation of mute, note, velocity, duration, position, and more
- Live performance view with full screen mode
- Recursive modulation (modulation of modulation) for mute and position
- Modulation graphing via Graphviz
- MIDI mapping of all parameters with learn mode
- Optionally transmits MIDI clock
