While I don't know a thing about the MIDI API, I have never been able to get
midi to work on my SB Awe64 ISA. It has, if I configure all of them in the
kernel, three seperate MIDI devices that NetBSD will recognize: yet playing
a midi has never once worked. It just hangs and I have to control-C it, and
then it waits a while before exiting. From sb(4):
Non-SCSI CD-ROM interfaces are not supported.
The MIDI interface on the SB hardware is braindead, and the driver
to busy wait while writing MIDI data. This will consume a lot of
I'm not sure how correct this is, because playing midi files under windows
has always worked fine on every soundblaster card I've ever owned. Perhaps
the driver is braindead, not the interface?
