MPDisco is a Node.js-based music server built to let teams and groups control a single music player together. Accessing an MPDisco server puts each user, after logging in, in a rotating DJ queue. Each user will be given one hour (by default) to control the playlist and music player.
MMLi is a simple Music Macro Language interpreter written in ISO C99. The Music Macro Language originated in 8-bit BASIC implementations (as part of the “PLAY” command), and can still be found in modern BASICs (like QB64) and in system software (like FreeBSD's spkr.c driver.) This interpreter features an example "mmlitest" program which can be used to translate MML sequences into beep(1) commandline arguments.
