Overview
Jamulus is free, open-source software for playing, rehearsing, or jamming remotely in real time over a broadband connection. It is described for choirs, bands, folk and classical musicians, music lessons, schools, and universities. In its client mixer, users can set the level they hear from each connected musician and use mute, solo, pan, and grouping controls. People connected to the same server can exchange text messages visible to everyone there. A connected MIDI controller can operate mixer volume, pan, mute, and solo controls, with availability depending on platform and version. Users may run their own server, but this is optional because clients can connect to listed or unlisted servers. Network conditions affect server quality; the manual says fewer than five players is usually fine on a slower home connection. Communications are sent without encryption, and normal use shares a user's Jamulus name, city, country, instrument, and skill level with connected servers, peers, and protocol-using third parties. When recording is enabled, unmodified servers show a notice, and the server operator controls recordings.
