Greetings,
For several years I have been preparing MIDI files to help our local choral singers learn difficult material. In particular I have produced MIDIs for music that is under a current copyright. These files are placed on our chorale website on a password protected, members only page. They can be downloaded by the members to be played on the member's computer.
My question is whether posting such files on a publicly accessible site such as CPDL violates the copyright. I would not post the actual score since that would clearly violate copyright, but since the MIDI is intended to be used in conjunction with a personally owned score does the MIDI also constitute a copyright violation? If you have your own music notation s/w then you can easily modify things like volume, tempo, and the like which you cannot do easily with an .mp3 file.
In particular, I'm thinking about the John Rutter Requiem and the Ariel Ramirez Missa Criolla.
Many thanks,
Bob

Re: MIDI FIles and Copyright
The short answer is, yes.My question is whether posting such files on a publicly accessible site such as CPDL violates the copyright.
Why? Because a MIDI file encodes the notes and durations of the piece, and these can be imported by any of several music notation programs to reconstruct the score.
It is no different from my posting:
49 74 a0 77 61 73 a0 61 a0 64 61 72 6b a0 61 6e 64 a0 73 74 6f 72 6d 79 a0 6e 69 67 68 74 2e
Once it is recognized that these are character codes, it is a simple matter to see that they yield the famous sentence:
It was a dark and stormy night.
You already alluded to the fact that:
And therein lies the copyright problem. One of the "and the like" things you can do is to tweak the results of the MIDI import and then circulate it, whether in print or PDF form, thereby potentially violating the terms of the copyright on the work in question.If you have your own music notation s/w then you can easily modify things like volume, tempo, and the like which you cannot do easily with an .mp3 file.
I'm not a copyright lawyer, and these are only my opinions, but I think they are held by many. My advice: Be VERY careful about such things.
