=== MIDI related === | |||
* Sometimes, incorrect music data is parsed to the MIDI parser, leading to a crash. This is occuring frequently in ITE, and rarely in IHNM. Perhaps it's related to some unhandled meta events. The crash always happens at sound/midiparser_xmidi.cpp in MidiParser_XMIDI::readVLQ2 at line 58. Refer to the bug report [http://sourceforge.net/tracker/index.php?func=detail&aid=1734416&group_id=37116&atid=418820 here] | |||
* When using the original XMIDI music resources, some songs play at the wrong speed. The worst example I've heard of this is the "Elk Fanfare" during the intro. It could be the meta events we don't handle, but at least the tempo event doesn't seem to make any difference. Maybe something in the data header instead...? | * When using the original XMIDI music resources, some songs play at the wrong speed.
