Toilet in Wonderland - some specific midi musics don't play without a custom soundfont and cause troubles (Windows - files included)

[Mimigris]

Name of the game:

Toilet in Wonderland, Version 2.2e (the English translation).

Player platform:

Windows, tested on version 0.7.0 and on the latest continuous build.

Attach files (as a .zip archive or link them)

File of the tracks in question are timetolearn.mid which plays in the forest map in said game, and zerotwo.mid which plays during the end of the game (you can test the tracks in another game if needed). Those are midi of tracks from Kirby's Fun Pak and Kirby 64.
TIW-midi-issue.zip

Describe the issue in detail and how to reproduce it:

In the forest map and during the end of the game, two different midi music should normally play. They does not seem to play without a custom soundfont on my Windows, and they will instead not be played at all. After having tried to play one of these tracks, the
Player will seem to be a bit "drunk" and will have some issues to play some instruments on some midi tracks (try to play Dungeon 4.mid or Opening 1.mid from the RTP of RPG Maker 2000 after playing one of these tracks in the Player without a custom soundfont, the start will be horribly wrong).

[Ghabry]

These MIDI files use alot of SysEx commands which likely mess up something. This needs testing if harmony.dll filters them away.

SysEx is used to send system specific commands to the MIDI device.

The ones with 126 at the beginning are the normal GM Reset SysEx. This is pretty typical to do (and harmony/we already do this for cleanup)

According to the fluidsynth sourcecode these "65" things are GS_DT1 commands, whatever that means :).

Adding it since it is likely related, but No.5 こうもりさんの花物語【２ｋ】 has the same kind of issue, on the map or in a level, no music is played without a custom soundfont.
