Hmm... After some debugging of the code in oss_envy24ht, it seems like the driver code is working. I added some more cmn_err outputs in the midi code and it seems like it can read the input events that is sent to it from my midi keyboard. The received events seem sane (when I print the RX queue and the input read) but it seems like the output gets lost somewhere on the way to the midi in device in /dev (midi00 in this case).
For example this is what I get in dmesg: Checking for input, status is 13 Trying to read midi, input is 80 /dev/midi01: Input buffer overflow As you can see here the RX queue (status) is 0x13 and the input is 0x80. However it seems like this trying to pass the information to the midi01 device (output/MIDI out) and not my input device! I think this explains why midi00 is always silent. But I have no idea why it tries to use midi01 instead of midi00 as it will only listen to input if i open the input device for reading. An other thing I noticed is it seems like I can't send and receive MIDI events at the same time. If I connect the MIDI in jack to the MIDI out jack and run the midiout and midiin examples from the OSS4 manual the output transmits put the input seems to get put on hold till the output is done. Is this a limitation of the current midi implementation in OSS4 or is it perhaps my soundcard? It seems quite dumb to have two MIDI jacks if you can only use one at a time... The software based midi loopback device seems to be able to. But i guess it differs somewhat from the MIDI implementation on the soundcards. Anyhow, it seems to me like I need to find out where and why it tries to output to the wrong device and I should be able to use my MIDI in jack. I would be really grateful if someone would try to help me out with this. Not necessarily with coding but just with a few pointers of hint on where the problem could reside.
