Another midi issue

[Omer Katzir]

For some reason I can’t generate pdf and midi at the same time, I must % the 
midi block or it won’t generate the pdf file. I got it working on other file 
similar to this one, but I can’t find out why it won’t do the same with the 
current one. I know it’s a lame question but I looked into the documentation 
and couldn’t find the right answer. 

All your help is appreciated.
