Hi all,
I have successfully installed Alsa 0.9 on my PC with a PCChips 810LMR
motherboard which has onboard SiS7018 sound (snd-trident module and
friends). I am running Mandrake 8.2. The archive of this list helped a
lot to nail down those subtle devfs issues.
Then I built rosegarden 0.1.6 for Alsa and the latest timidity for
software wavetable synthesis. The playback from within rosegarden sounds
downright terrific! Wow...!
But I would like to enquire about iiwusynth because I understand
iiwusynth is better aimed to soundfonts (I know that I can use
soundfonts with timidity too). Has anybody got it working with Alsa 0.9
and SiS7018? Roger Brown (Rosegarden developer) reports it works for
him. For me it doesn't. I have recompiled with --enable-debug and set it
suid root. This is what i experience:
When iiwusynth is running, it does not open a midi port, i.e. i see
nothing related when i type 'aconnect -o'. Consequently, in rosegarden
i don't see the intstruments from the used soundfont (as I said,
rosegarden works fine for me with timidity). But iiwusynth does not
complain. It says
debug: using alsa audio driver
(loads of soundfont info)
debug: using alsa midi driver
iiwuplay does not work either. It outputs some info about the midi file
and prentends to be playing, but there is just silence.
And now on to the most astonishing thing: I built the swami soundfont
editor (successor of smurf) which uses iiwusynth for on-the-fly testing
of instruments. And that connection works! But I still dont see a midi
connection from swami to iiwusynth with aconnect or alsa-patch-bay.
However, the transport (i.e playing chosen instruments at certain
pitches) does work and I hear the notes. Also, when I turn off iiwusynth
playback from within swami and then turn it on again, then it remains
silent until I restart swami.
The SiS7018 has onboard wavetable synthesis too. I can see those ports
with aconnect. Maybe iiwusynth requires to be the only synth for correct
operation and gets confused??
BTW, does anybody know how to load a soundfont into SiS7018 for hardware
sound synthesis? According to the dox, snd-trident has even option to
change the wavetable memory.
Thanks in advance for any pointers,
Frank
