If you have tried other midi's on my site and could not hear them. This is what you must do:
Check if you have Windows Media Player(almost everyone has it)It should be in StartMenu/programs/accessories/entertainment
You better know where the start menu is!
If you do not have it, go to download.com and download it!
Open the windows media player
Select "View" on top and then "Options"
Select the "Formats" tab on top.
Scroll down the list a little until you see "Midi File"
Click on the checkbox until it is a WHITE box with a check. NOT GRAY!
Select Ok and close the media player. Now whenever you open a midi file it will open with this.
