MusE is computer software, a sequencer for Musical Instrument Digital Interface (MIDI) and audio, with recording and editing abilities.[2][3][4] It was originally written by Werner Schweer and now is developed by the MusE development team. It is free software released under GPL-2.0-or-later.
MusE aims to be a complete multitrack virtual studio for Linux. As of 2020, it has no support under other platforms as it relies on Linux-only technologies, such as Advanced Linux Sound Architecture (ALSA). It also supports the Linux Audio Session Handler (LASH).
For version 0.7, the music notation feature was removed from MusE; this code later became the cross-platform notation app MuseScore.[5] A scoring feature returned to MusE in version 2.0.[6]
