Hi,
I have this error that I don't know how to fix.
I was using Craig Stuart Sapp's Midiio library to control
the Emu10k1 wave-table synth. It *was* working until I reinstalled
my linux system. I have put evrything back the way it was, and
now I get these errors when I use the Midiio library:
--ALSA lib rawmidi_hw.c:227:(snd_rawmidi_hw_open) open /dev/snd/midiC0D3 failed: No such device ALSA lib rawmidi_hw.c:227:(snd_rawmidi_hw_open) open /dev/snd/midiC0D4 failed: No such device ALSA lib rawmidi_hw.c:227:(snd_rawmidi_hw_open) open /dev/snd/midiC0D5 failed: No such device ALSA lib rawmidi_hw.c:227:(snd_rawmidi_hw_open) open /dev/snd/midiC0D6 failed: No such device ALSA lib rawmidi_hw.c:227:(snd_rawmidi_hw_open) open /dev/snd/midiC0D7 failed: No such device
--
I know I should have backed up my previous working configuration, but I didn't. One thing that has changed is that I'm using alsa-0.9.6 now, and before I was using the previous alsa (0.9.4?).
I've put the output of : 'pmidi -l' and 'aconnect -o' at the bottom.
Here's my questions:
Whats the correlation between the /dev/snd/midi* devices and the alsa/Emu10k1 wavetable ports?
Where can I get more info regarding the alsa/wave-table/sequencer issues?
Can I use aconnect and/or virmidi-devices to fix the above errors?
Or, can someone reccomend a C/C++ library/example that will show me how to write to the alsa wave-table devices?
If my questions are lacking detail, what can else can I provide?
If my questions are off-topic where should I go?
I've STFW. I've tried to RTFM, but there isn't one. I definitely would like to GAFC. (Im *NOT* criticizing linux-audio/alsa, I'm making light of my lack of knowledge :] )
*ANY* input would be greatly appreciated. I realize that my question is a little under-developed, but I've been sitting on this problem for a while now, and I can't get anywhere.
