Keep in mind that rosegarden can also actually work without jack and with just (Alsa) MIDI in/out. I know it's maybe not exactly a 'simple' sequencer per se, but you can use it in 'simple' ways and set it up e.g. to start with just 16 midi track (no audio), that's how I have my default template. seq24 and the newer versions/forks (e.g. seq66) also come to mind and the editing interface resembles a (very basic) piano roll. Although seq24 is more aimed at live so you don't have a typical 'track' layout. There is non-sequencer (but you'll need a bridge for alsa midi). Never really used it though as I couldn't get accustomed to it's 'piano roll'. There are a bunch of other sequencers which were quite straightforward like Jazz++ but I think most are abandonware these days. Hope this helps. Lorenzo.

Rosegarden would be far too complicated, and would be trivially easy to get into a state the intended users wouldn't be able to get out of - and I say that as someone who uses it exclusively! Seq 24, 64 etc are tracker style and not really suited to continuous live recording. Midieditor is exactly the right format, but doesn't appear to have any current activity. It's a debian package so not editable. Also the GUI somewhat primitive and has odd quirks. It always opens full screen, and seems to insist on GM instrument names. Dragging a note expands it until you let go, when it snaps back to size at the new position. Rather strangely, when recording incoming mIDI it doesn't show notes as they are played, or even finished, but only after you completely stop. helio-workstation I haven't been able to build yet. Maybe I'm getting stupid in my old age, but I can't seem to find any real build instructions. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.
