Hello list,
I'm new to audio recording, and have a couple of unsolved questions
after getting my basic setup working. I've searched the archives
using google (is there a list-specific search somewhere?), but haven't
found a solution. I'm currently using
- pc with sblive! soundcard
- 2.6.20-rt8 kernel, by patching stock debian kernel 2.6.20
- external evolution usb midi keyboard
- external 4-channel mixer
- timidity as a soft-synth
- ardour 2.0 for audio recording
- rosegarden for midi recording.
- jack + qjackctl to connect it all
All that seems to work reasonably well, and since the realtime kernel
there are no noticeable latency problems. I do get the occasional
xrun (about once every 5 minutes or so) but it hasn't been
bothersome.
The thing I cannot get to work is midi playing through the sblive
soundcard. I've followed countless howto's, yet all I get is dead
silence. The card works for normal audio, all modules including
snd_emu10k1_synth and snd_emux_synth. I've tried loading the
soundfont like so
aweset -v init -> initializing AWE chip
asfxload 8mbgmsfx.sf2
It seems to work if I inspect /proc/asound/card0/wavetableD1:
Device: Emu10k1
Ports: 4
Addresses: 17:0 17:1 17:2 17:3
Use Counter: 1
Max Voices: 64
Allocated Voices: 61

Locked Instruments: 1849

But all that comes out is dead silence, wether I route the keyboard to
the soundcard or try through rosegarden. Here's the output of
aconnect -lio just after loading the soundfont:
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '

client 14: 'Midi Through' [type=kernel]

3 'Emu10k1 Port 3 '
client 20: 'MK-225C USB MIDI keyboard' [type=kernel]
0 'MK-225C USB MIDI keyboard MIDI '
I've tried to connect 20:0 to 16:0, and also to 17:0,1,2,3, to no
avail. What should I be connecting? Any other hints as to why my
sblive card won't play midi?
Here's the output of lspci -v:
00:0d.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 04)
Subsystem: Creative Labs CT4850 SBLive! Value
Flags: bus master, medium devsel, latency 32, IRQ 17
I/O ports at a400 [size=32]

Any help will be much appreciated.
Kind regards,
Hein Zelle
