MIDI programming

	Hi,
	Can anyone give me a hint at writing a simple

program to read MIDI keyboard input? I don't want to parse this input, just to test the presence of the keyboard under Linux.

Well, all you do is

fh = open("/dev/midi00", O_RDONLY); // (Port 00 hardcoded)

and then you read() as from any character dev. close(fh) when done.

dd bs=1 if=/dev/midi | od -t x1 --width=1

..works for me. I strike a key and get:

0000000 fe
*
0000020 90
0000021 5d
0000022 35
0000023 fe
0000024 90
0000025 5d
0000026 00
0000027 fe
*

which is a bunch of activie sensing bytes, a note-on/note-off pair and more active sensing bytes. :)

	Hi!

	I've tried this before but never got a byte :(

Maybe, my configuration is incorrect:

OSS/Free:3.8s2++-971130
Load type: Driver loaded as a module
Kernel: Linux flex.dorms.msu.ru 2.2.14pre18 #2 Wed Jan 5 22:17:13 MSK 2000 i586 Config options: 0

Installed drivers:

Card config:

Audio devices:
0: ESS ES1868 AudioDrive (rev 11) (3.01)

Synth devices:
0: Yamaha OPL3

Midi devices:
0: MPU-401 (UART) MIDI

Timers:
0: System clock

Mixers:
0: Sound Blaster

I've tried both uart401 and mpu401 modules but none
of them responses to key presses. Maybe there's some trick with interrupt setting?

The soundcard is detected right, audio and midi
playback is ok, but I can't read MIDI.

Can anyone help me in getting my MIDI keyboard
working under Linux? (In Windows it works perfectly.)

Thanks in advance,
Taras
