- At at least one place in INDY4 the game attempts to send a Roland MT-32 patch to the Amiga driver. This will fail and thus not cause any harm, but I have added a check nonetheless. The original Amiga driver ignores sysex messages that don't have the iMuse manufacturer id 7D.
- In INDY4 the iMuse player thinks it has a percussion channel due to the fact that it plays ROL resources. This should also be irrelevant for the actual playback, but I have added a check for that, too.
