GM Midi file Editor - simple

Friend of mine is doing live performances with Gm midi files. Shes got no idea of audio software but wants to edit (cut trim tranpose merge ect...)her midi files. Any recommendation for a very simple midi file editor? Reaper is far too complicated. Thanx in advance

All sequencer piano rolls are pretty much the same, so she's going to have the same problems with every other one out there. How about notation? She could use a free notation editor like MuseScore.org and edit the note there...

nah there must be a simple beginner friendly editor out there...with big knobs ;-) ist just for mainly transpode and cut midifiles (the comple track) maybe merge some tracks together...

Show her how to do midi editing in Reaper, and tell her to ignore the rest...or theme up something that strips away all of the other stuff for her.
