Gateway command line: GATE MT32
After the intro, the first piece of music plays fine.
There should be a second piece of music immediately following the first, but it doesn't play.
MPU interrupt generation stops at the end of the first piece.
The correct behaviour was confirmed on a DOS PC with a Roland MPU-IPC-T interface.
Fixed this bug by adding new lines of code to the specified files. Refer to: https://skydrive.live.com/?cid=5650b73edd2496b3&id=5650B73EDD2496B3%216628 and download the DOSBox-MT32-Patched.zip file. Enjoy!
