Hi there. Is the file a .bmtp or .bmte? If its .bmtp you'll be able to edit it using Bome's MIDI Translator Pro. If its a .bmte then it's encrypted and impossible to edit. Just to add Bome's is not free but it is well worth your cas. There's a demo version to try put unless you're already pretty experienced with MIDI and controllerism then be prepared for a learning curve that's pretty much vertical. It's worth the effort.
