LinuxBand is a GUI front-end for MMA (Musical MIDI Accompaniment). Type in the chords, choose the groove, and LinuxBand will play a musical accompaniment for you. It’s an open source alternative to Band-in-a-Box featuring: an easy to use graphical interface, an open and well-documented data format, and output to JACK MIDI to facilitate co-operation with other audio applications.
mmq plays arbitrary audio files gaplessly and continuously without needing a predefined queue. mmq is an exercise in minimalism, so it is more about avoiding needless features than anything else. mmq may be used standalone or managed by a larger application. mmq is only configurable at build time. Currently, FLAC decoding and SALSA-lib audio output support are implemented.
