Still Cannot get music to work in MMF

I am working on a game where the player runs a radio station. What I want to do is play a variety of music of different formats depending on what format the station is.
AS a global variable I have the format number (1-8)
As a global event I have:
if format=(format number)
play (mid file)
When I run the game, the game slows up and no music plays.
I have tried other methods, but with very little success.
When I start the frames with the music, it plays, but when I try to use a global, it crashes.

Can you upload an MFA file so we can look at it?

First guess is the if format=(format number) is triggering over and over because you didn't restrict it to 1 time or change the format number to something else.

Second guess is you have the synth volume turned off in Windows itself.
