If you have multiple chains selected when you do an ao-attach or ao-add
then the output will be attached to *all* the selected chains. I think
this is the only time that having multiple selected chains is useful
(but don't quote me on that :)
So:
c-add t1
c-add t2
c-select t1,t2
ao-add fred.wav
makes fred.wav the output for both chains.
Hope that helps.
With regards to frontends for eca, I am working on one myself. I hope to
have the first release in a month or so. It will try to preserve as much
of ecasound's semantics as possible, and even give you interactive mode
access. I'll try and get a screenshot of the current version up
somewhere for people to look at and make suggestions on.
Cheers,
Stuart

Ecmdr looks good, but just doesn't suit my purposes, and I started work
on my frontend quite a while ago. I generally create ecs files by hand,
them run ecasound in interactive mode and use the command line to tweak
parameters while the song is playing. What I wanted was to be able to
see, and tweak in real time, as many params as possible, and still have
access to the command line. I wrote an early version in python/tkinter
that worked okay but I found tk a bit limiting. I recently rewrote it
from scratch in python/qt and it's getting close to what I want.

Ooooh yep. There certainly are. I'm trusting ecasound to report any
problems. The hardest part is keeping the gui in synch with ecasound,
but I think Ive got that under control.

Me too, so I've tried to make as much visible at one time as humanly
possible.

They have their uses, but I think that making the user shift their
attention a lot is usually a bad thing.

Me neither. Nor am I a regular perl hacker, so modifying ecmdr was not
an option for me.

I basically write songs using muse or rosegarden, then record the live
parts using ecasound. Then I record the midi tracks to audio files and
use ecasound to do the mixing. So I'm trying to make ecasound look like
a mixing desk (sort of) more than a multi-track recorder.

Looks that way :)

Hi all,
sorry for being slightly OT. Would you recommend me
some links in order to make my pregnant wife listen to
some relax music?
Many thanks for your help,

Hi
In general I appreciate fsck running at boot from time to time. But not
when I'm on stage trying to set things up in a hurry. Is there a way to
quit fsck when it has kicked in, so that it'll run at the next boot, for
instance?

error compiling an ALSA demo program : invalid conversion from void* to
pollfd* ?
I see that pollfd is a struct ufds pointer.
I did not write the code so I'm somewhat lost, could it be a compiler
(switch) setting problem or something else?
The conversion is not valid C, as far as i know, but then why would it be in
this demo like that?
Thanks,
Daniel.
Thanks for reply.
I wanted to try by myself and I made last night a
quick hack for extreme time stretching by using FFTs.
I like the results very much.
Here are some demos (the links will work only for few
days):
Original sound is this:
http://zeus.integrasoft.ro/~nop/1stretch_paul_in1.ogg
Stretched (over 60x) is this:
http://zeus.integrasoft.ro/~nop/1stretch_paul_out1.ogg
Please tell me your opinion about the stretched sound.
The program is not complete (is just a quick hack
written in about one hour), but if you are interested,
I can put it somewhere on net (and make it usable and
improve the quality :) ).

Hi y'all
I have a bcf2000 that's been working well. Sometime in the last 2 months
or so (I've been busy with other things) it stopped responding to inputs
- ie the sliders don't move and the buttons and LED rings don't light up
in response to incoming midi - they work fine if they're triggered from
the unit itself. However, Ardour and Rosegarden both respond to inputs
from the controls, and if I can see incoming midi data if I use amidi.
Re-sending the 1.10 firmware worked fine, so it's not a problem with
sending midi data to the unit.
I've tried saying
amidi -p hw:2,0,0 -r tmp.syx
and then moving a slider, and then using
amidi -p hw:2,0,0 -s tmp.syx
to send the exact data back to the unit (after I've put the slider
somewhere else). But the slider doesn't move.
Same story using cat and the /dev files.
I'd really appreciate it if someone could try out the above and let me
know if it works. Then I'll know whether to take the unit to be
repaired, or to carry on fighting with my setup.
FWIW, I'm using 2.6.16-rt23, and alsa-lib-1.0.11.
thanks
John

Hello,
I'm looking for a LADSPA plugin that acts as an automatic
leveler for an audio stream playing different songs, which
will have (very) different volumes.
A simple compressor wouldn't suit my needs since it would
either sound too low for some songs or smash the sound for
other songs.
Actually I used such a plugin (I think it also was a command
line tool) some months ago but now I don't remember its name.
Any hint?
Many thanks,
Pau Arumí
