Believe it or not, I do most of those things using the abc file format with a selection of abc tools: voices - V1, V2, etc. playback - ABCMus and others cut/paste/copy - pick an editor that supports it tablature - jaabc2ps and others key / time signatures - add as needed lyrics / fingering / chord symbols - add as needed print ps format - abc2ps, jaabc2ps and others. I use ghostwriter/viewer and convert to pdf format when needed MIDI input / output - midi2abc, abc2midi and others. This isn't as clean as I like since many like to add rests where not requested, but there may even be a solution for that file format conversions - pick as needed. There are several.
Most of the above are simply small tools that work with abc format files (or produce them). Additional tools will surround multiple tools mentioned above and do those tasks when called upon in a GUI environment. Personally I just use the command line approach with the exception of ghostviewer when converting ps files to pdf files. Good luck.
