minimal reproducible example

XM6 TypeG[1] is a SHARP X68000 Emulator.
When I use STed2[2] inside XM6 TypeG, some MIDI note-on messages aren't sent to
MIDI devices (e.g. Timidity++).

@honda_ken, an original reporter on Twitter, tweeted XM6 TypeG sounds strange
on Wine. He also informed me that Wine outputs the following message on his
console:
0338:fixme:midi:modData ooch 3c
0338:fixme:midi:modData ooch 403e
0338:fixme:midi:modData ooch 3e
0338:fixme:midi:modData ooch 4040
0338:fixme:midi:modData ooch 40
0338:fixme:midi:modData ooch 4041
0338:fixme:midi:modData ooch 41
0338:fixme:midi:modData ooch 4043
0338:fixme:midi:modData ooch 43

I setup XM6 TypeG environment on my PC and I can reproduce the issue.
Preparing the environment is a bit difficult, I wrote a minimal reproducible
example (shortmsg.c).

Steps to reproduce:
1. Compile the source code.
   % i686-w64-mingw32-gcc -o shortmsg.exe shortmsg.c -lwinmm
2. Setup your favorite MIDI device, e.g. Timidity++.
   % timidity -iA &
3. Run the executable (argument -1 means we use the MIDI mapper).
   % wine shortmsg.exe -1

Expected result:
We can hear the piano voice, C, D, E and F.

Actual result:
We can hear the piano voice, only C.
