The two apps from #26997 #23756 use midiStream with DCB_CALLBACK_FUNCTION.
They need patch 1+2.

I've not retested ff7 from bug #9220 which uses midiStream too.

The apps that would benefit from patch 1/2 alone are those that
use midiStream with one of DCB_NULL, WINDOW or EVENT.

I've not investigated which MIDI apps are of the required kind or if
they use mcimidi, midiOut directly or midiStream with DCB_FUNCTION.
