I'm at a loss here. I just want to crop a midi song I have, but after downloading and screwing around with 3 different programs I can't get it done. I have a midi that is 2 minutes long. All I want to do is cut off the first 30 seconds, without ruining the rest of the song. Does anyone have any idea what app I can use, or if you have one and its a quick job, can you just do it for me?
