#1910 LOOM: Overture sounds awful with MT-32 emulator

[Gunther Schmidl]

With the MT-32 ROMs, both in emulation and real MT-32
mode, the first minute or so of the Loom overture (from
the MT-32 patch provided by LucasArts) is distorted and
sounds nothing like it should. Then, suddenly, it starts
working fine. Using native Win32 MIDI, the overture
plays normally.

Forgot to add: this is ScummVM 0.8.0CVS (Dec 29 2004
16:00:22) with Vorbis/FLAC/MP3/zLib/MPEG2 on Windows
2000.

Sounds fine to me using the built-in MT-32 emulation code in
Win32 0.8.0 CVS Feb 20 2005 11:25:04 daily build.

I listened again with the latest build -- if you pay attention to
the rising and falling tone that plays almost immediately, it
changes speed almost randomly. I am not talking about the
normal intro, by the way, but the overture you get with the
patch from Lucasarts.

Kingguppy, maybe you have an idea on this one? Feel free to unassign /

This is specific to the MT-32 emulation, not actual playback
using a real MT-32. I think this is what the author of this
report was trying to clarify. If you play the extended
Fatman overture using MT-32 emulation, notes are missing
altogether and most instruments sound off-key. This will
likely be fixed as the MT-32 itself progresses, but is not
due to any fault in the imuse/midi parsing code.

"as the MT-32 emulation progresses", that should have said.
Obviously, the MT-32 itself has not 'progressed' in over 15
years :)

I'm not entirely sure what the original reporter meant, but
I'm assuming that "in emulation and real mode" means "with
and without 'True Roland MT-32 (Disable GM emulation)'
selected".

tbcarey's right, this is a Munt issue, and it will improve
as we work on the accuracy of the emulator. I'll leave the
bug open here anyway

tbcarey is correct -- not having an MT-32, I can only compare
it to a) the other MT-32 emulator out there that works as a
Windows device driver and b) native Windows MIDI. In
ScummVM's MT-32 emulation mode, the music plays wrong;
in native Windows MIDI, it does not.

As far as I can tell it works nowadays with the latest build from master (3e47203d645b24b8d94cb2ac742072764e49ef04), probably it got fixed when we switched to the new Munt code.

Closing as works for me.
