I read some time ago a great explanation regarding using music when assemblimg either videos or slide shows. It indicated that it is unlawful to use music without proper permission. While I can appreciate the explanation fully, my question is this; can I add music that is created using MIDI. Essentially is the song created commercially the issue ie can I use the song created by using MIDI without concern who is playing it or are the song titles protected also. Any thoughts on this is greatly appreciated.
