I made a bunch of these when I worked with the Jazz++ sequencer. I found them quite useful and fun. For instance: - take a midi sequence, copy it, paste it in a bit later with lower velocity. I used this for delay-line like effets. - same as above, but reversed for reverse effects I find these sort of things interesting and would be willing to put some effort into it (the difficulty being that I know next to nothing about the rosegarden codebase) >> Oh ok, not really what I had in mind either...
