please review the midi editing features of guitar pro 5 software. this video is a good place to start: [url removed, login to view]
i am looking to have a desktop app (with the possibility of porting it to a webapp) that will basically be a multitrack midi editor very similar to guitar pro.
one of the main differences however will be that there is no need for RSE/audio sampling. just midi is fine.
please provide samples of midi related work you've done and how long you expect a project like this to take
