Hi electrotum,
I've been looking for releases allowing music creation with maximum ease, and finally discovered LibraZik 3 which is buster-based and great !
As the main dev of LibraZiK, thank you for those kind words.
Maybe it is time to update this page : https://wiki.debian.org/DebianMultimedia/Links I think some distros may be deleted or marked obsolete. Maybe others also added ?
I've added LibraZiK, removes musix (which gives a 404 nowadays), and orders the list in alphabetical order.
Hope that helps, Olivier
