 =====
 
-* [Open Music](https://github.com/openmusic-project/OM6) - a visual programming, computer-aided composition environment. [GPL3][2].
-* [OM7](https://github.com/openmusic-project/om7) - a new implementation of the OpenMusic visual programming and computer-aided composition environment including a number of improvements on graphical interface, computational mode, and connection to external software libraries. [GPL3][2].
 * [Incudine](http://incudine.sourceforge.net/) -  Music/DSP programming environment for Common Lisp. Useful to design software synthesizers or sound plugins from scratch. It is also a compositional tool that allows to produce high quality sounds controllable at the sample level, defining and redefining the digital signal processors and the musical structures on-the-fly.
 * [cl-collider](https://github.com/byulparan/cl-collider) - A
 [SuperCollider](http://supercollider.github.io/) client for CommonLisp. With a [tutorial](https://github.com/defaultxr/cl-collider-tutorial) and [live coding demos](https://www.youtube.com/watch?v=xzTH_ZqaFKI). Public domain.
-* [csound](https://github.com/csound/csound) - A sound and music computing system. Includes CFFI and FFI interfaces for Common Lisp.
-* [CLM](https://ccrma.stanford.edu/software/clm/) - Common Lisp Music is a music synthesis and signal processing package in the Music V family. It provides much the same functionality as Stk, Csound, SuperCollider, PD, CMix, cmusic, and Arctic — a collection of functions that create and manipulate sounds, aimed primarily at composers (in CLM's case anyway).
   * [common-tones](https://github.com/theraphonics/common-tones) - a fork of CLM5 with modern Lisp (ASDF, cffi…). [BSD_3Clause][15].
 * [cl-patterns](https://github.com/defaultxr/cl-patterns) - a system for composing music via Lisp code, heavily inspired by SuperCollider’s patterns system, with aims to implement much of it, but in a more robust, expressive, consistent, reflective, and lispy way. Audio output through SuperCollider, with preliminary support for Incudine, and MIDI through ALSA.
 * [cl-openal](https://github.com/zkat/cl-openal) - bindings for the OpenAL audio library. Public domain.
-* [Common Music](https://github.com/ormf/cm) - the repository of an
-ancient version of Common Music (version 2.12.0), the presumably last
-version which ran on Common Lisp dating from around 2007-09, before
-work on Common Music shifted to (scheme-based) cm3.
 * [Slippery Chicken](https://github.com/mdedwards/slippery-chicken/) - Algorithmic composition library which outputs Midi, Common Music Notation, pdf-score via Lilypond and sound via Common Lisp Music. [GPL3][2].
-* [Common Music Notation](https://ccrma.stanford.edu/software/cmn/) - Common Music Notation (CMN) provides a package of functions to hierarchically describe a musical score. Public domain.
 * [cm-incudine](https://github.com/ormf/cm-incudine) - extends Common Music 2 with realtime capabilities. GPL2.
 * [Mégra](https://github.com/the-drunk-coder/megra) - A mini-language to make music with variable-order markov chains and some other stochastic shenanigans. [GPL3][2].
 * [Music](https://github.com/MegaLoler/Music) - A framework for musical expression in Lisp with a focus on music theory (built from scratch, unrelated to Common Music).
