Hi Bruce,

If you want to drive your external MIDI gear, just use

Hello Frank
Thanks for the reply. Just for fun, I downloaded the alsa code and tried
the midi fifo (midiC0D0), and got fairly chaotic results, which I suspect
was due to the 'timer' frequency, which I don't really understand what
it is. As far as the lack of an interupt goes for the card, upon reflection
I would imagine writeing a polling type driver for a multitasking system
as something of a hideous nightmare. Fortunately I am not stuck with
the cmipci card. I can replace it. I also have another option which I like
better. The korg has a jack for a standard serial port which I'll try to
hook up.
