I need a little more information about what version of the game you are using and what you have done to trie using the game. Possibly windows isn't set up to output the MIDI sounds correctly. You might need to go to your multimedia section of the windows control panel and make sure the correct defaul midi output device is selected. (note that this is removed from the win vista/ win7 control panel)i tried this 'superpatch' but the midi sound dont come.
I am using a xp x64 edition.
What could be the reasson ? what other fixes we could to try ?
