[linux-audio-user] why this works now ...

[Eric Dantan Rzewnicki]

Well, now that I know ecasound's rtnull is not meant for use with the 
kind of thing I was trying to do and remembered that you can't add a 
chainop to 2 chains at once ... This whole thing works in one ecasound 
instance, with or without jack ... I feel really foolish for making all 
this noise on the lists all week ... <hangs head in shame>  I'll try to 
write up something for the ecasound docs to explain this so others don't 
make the same mistake.

There is still a slight zipper noise in the -ea: controller. Steve seems 
to think that's related to the analogueOsc somehow, but I don't see how 
it could be since the plugin doesn't have an amplitude control. The 
glitchiness in the audio output seems to be pretty much gone. It was 
probably a symptom of the xruns due to the rtnull object and the rest of 
the settup running off different clocks (system vs. soundcard).

One weird thing, though. Before I remembered to split the doubled chains 
out into separate lines I tried to get the previous version to work with 
-i:null instead of rtnull. It worked to play via jack, but, as soon as I 
connected another ecasound to the first's jack ports the first ecasound 
got kicked out.

I haven't tried checking on the .ecs problem, yet. But, I'm guessing I 
probably just messed something up with that, too. :(

Oh well. Thanks for everyone's help. The working ecasound only version 
is attached. Sorry for cross-posting again, but since I went and spread 
this "problem" all over 4 different lists, I figured I should wrap it up 
on at least 2. I figure most people on LAD and jackit-devel are probably 
on LAU, too.

The upside is we have another positive experience with the patched 2.6 
kernel to report. And for myself, I'm finally using this controller I 
bought almost a year ago to have some fun making sounds. I can go ahead 
and write my randomized ECI versions as well. I'll also look into adding 
interpolation to the analogueOsc Hz control.

Thanks,
Eric Rz.
