kids songs

2008-09-09 by Spencer_Lists

Joan,

I got your kids songs and tried to play them with my file player. Your files all use note off events instead of note on with velocity 0 to turn them off. This is unusual although legal MIDI. What is most strange is that the velocity in the note off message varies and is not 0. I have never seen this before. It may be some way of encoding aftertouch with which I am not familiar.

In order to get my players to work with your files I simply convert the note off vel xxx to note on vel 0 and they play fine. I am pleased that I discovered this and made the change to my player so it will handle this use of MIDI that I never considered. However I would like to know why these files are made that way. Did you do it intentionally? Were they recorded on a Disklavier? Any other information would be helpful.

I probably never had this problem before because I never wrote a file player and all of my previous programs treated note off messages differently. I needed to make my processing loop as tight as possible for the player and simplified the note event parsing. 

It is great that you have these kids songs. I support anything that encourages kids musically. It would be even better if they had lyrics. Do you have any intention of adding them?
