Back in the day there was a very nice and simple little MIDI sequencer for X-Windows called Seq24 that I used every now and then. Of course there are much more complex music software that also happens to have MIDI-support (LMMS, Renoise, ...) but I liked Seq24 because it only did short MIDI patterns and had quite good GUI (holding down various modifiers and using the different mouse-buttons to do most edits). Searching I get a link to a URL that looks like it could have been the Seq24 home page, but Firefox throws up a security warning for that domain. There is also a hit for this project that claims to be based on Seq24 and that has commits as recently as a few days ago, so maybe this is worth looking at: https://github.com/ahlstromcj/seq66 https://github.com/ahlstromcj/seq66
