Midi-output not generated

[Paul Rijke]

Hi there,

 

I have the following drum excersises written out for my daughter. It prints beautifully (except that I am not able to set the vertical spacing to my linking, but that's not that big of a problem). I just wonder why the midi-file (which is generated) only is 149 bytes long and contains no sound. Dows anybody know what's going wrong? There are no errors or warnings in the log.
