I don't need that for now. What I need are the 119 missing bytes between
17.015:003b:trace:midi:modLongData dwBufferLength=125 !
17.015:003b:trace:midi:modLongData                  F0 42 40 ... 00 00 00

Please copy&paste & adapt this code to produce a full hex dump:
http://source.winehq.org/source/dlls/winmm/winmm.c#L1066

In particular, I want to know if there's some F7 amid that data
(remember that your original patch precisely stopped at a F7...)
and what the bytes following that F7 look like.

That's a possible interpretation, however your log snippet shows no
sign of sending another message.

Do you have MIDI/ALSA debugging tools that can show you whether ALSA
truly sends out the 125 bytes?  That too would help identify the problem.

Thank you,
