SysEx issues with real MT-32

|Game:||Quest for Glory 2|
ScummVM version: 1.3.0svn54897 (Dec 13 2010 11:14:31)
Version: Quest for Glory Anthology CD-ROM
Platform: Windows 7 x64
When I launch Quest for Glory II: Trial by Fire in the ScummVM version listed above on my real MT-32, I get an \"Exc. Checksum error\" while ScummVM is uploading the SysEx banks (which indicates that ScummVM is probably sending the SysEx data too rapidly). I then get title screen music that sounds noticeably different from what I hear when running the original Sierra interpreter version in DOSBox.
I\'ve made some recordings using Audacity just for this bug report; you can find them here: http://www.multiupload.com/L0O83O213Q
The files are one minute recordings of title screen music, with descriptions as follows:
qfg2-dosbox.ogg - Recording while playing original version in DOSBox at 1800 cycles (avoids same "Exc. Checksum error").
qfg2-scummvm.ogg - Recording while playing in ScummVM.
qfg2-scummvm2.ogg - For this one I started the game in DOSBox, then cut off the MIDI connection to my MT-32 and switched over to running the game in ScummVM, then restored the MIDI connection. Net result is running with ScummVM but with original version SysEx.
