Adam,
That code is in there because there were some claims and some
uncertainty about whether Microsoft's code could possibly issue a
callback while another was in progress. The feeling was no, it won't
happen, but if there *were* concurrent callbacks on the same device, it
would cause problems, so some checks were added. It seems plausible that
there could be concurrent callbacks on *different* devices, and it
sounds like a bug that this is tripping the assert().
I want to look at the code, because I don't think anyone has really
considered whether the code is safe for multiple processors concurrently
handling MIDI callbacks. In the meantime, you could either read the code
too or just take out the entry count and assert() code and see what happens.
I'll report back when I've taken a closer look.
Thanks for the report -- it's a real issue that needs some attention.
-Roger
