Perhaps http://msdn.microsoft.com/en-us/library/dd798477%28VS.85%29.aspx
 "A stream buffer cannot be larger than 64K" => INVALPARAM
(which is about midiOutPrepareHeader, while midiInPrepareHeaders says nothing
like this).

Now somebody needs to do additional testing to determine when/how
midiIn/OutPrepareHeader may return INVALPARAM for buffers >64K and when not,
i.e. how to detect a stream buffer.
I can add some tests to my emerging MIDI testsuite.

BTW, for comparison I'd like to see a +midi,+winmm,+driver application log with
Lauri's hack that permits a larger buffer size.
