Re: [PATCH v4 0/1] MR10581: winealsa.drv: Simulate blocking calls midiOutLongMsg.

April 6, 2026


      Some justification for this patch. After noticing SysEx data not being transmitted properly to my Roland MT-32 when going through Wine, I created a test program that confirmed that the midiOutLongMsg call on Windows is blocking. Attached are four log files generated by my test application:

[win10-cb.log](/uploads/c0f6cc5c97a53988d40a516705ceacea/win10-cb.log) on Windows 10, with a notification callback function

[win10-direct.log](/uploads/096c54ab6975bbfa4770118ba76e2c90/win10-direct.log) on Windows 10, without a notification callback

[wine-cb.log](/uploads/33974b0ed3510c31693b7bc8848a02a5/wine-cb.log) on Wine, with a notification callback function

[wine-direct.log](/uploads/540320fa4d45e73b9d52e14451f1682a/wine-direct.log) on Wine, without a notification callback
