Hi,
I got an Edirol FA-101 and seems to be working fine with Planet CCRMA/Fedora
7. The only problem I found is that it seems the output level is too high. I
have a pair of Adam A7 monitors plugged to it and I have to set their levels
to -30db, and even when I set them to the minimum (-60db) I can still hear
something! Is this related to the frebob driver? Is there a way to lower the
volume in the outputs?
Thanks!

There is a test application for setting the volumes. But you have to
compile the freebob source yourself, since it is not shipped normally
(after all it is only a test application so far).

Hi Daniel,
Thank you for your response. I found a thread about that test application
and I've been trying to build libfreebob but I had problems with it not
finding libpthread. I have Fedora 7 and can't find the devel package of
pthread anywhere.
Cheers,
Hector

Ok, I got it to build (I was missing gcc-c++). I ran the different test
programs and I couldn't find the one that reports about the volume.
test-freebob gives this results, but I don't know if there is any volume
information there:
$ ./test-freebob discover

I read about a test-volume program but I couldn't find it in the latest

As it seems the test-program was moved away to the libfreebob-1.4

to set the level according the notes.
Hope that helps,

Thanks Daniel,
I checked out again from SVN and rebuilt. Now I have the test-volume program
but this is what I get when I try to run it:
$ ./test-volume 0 5 -32768
/home/hector/Desktop/libfreebob/tests/.libs/lt-test-volume: symbol lookup
error: /home/hector/Desktop/libfreebob/tests/.libs/lt-test-volume: undefined
symbol:

Also I noticed that on that old thread where this test utility is discussed
( http://linuxaudio.org/pipermail/linux-audio-user/2006-November/039911.html)
there is mention of not being able to set the outputs with it. Is this
still true? What I need is to lower the volume of the outputs. Also in that
thread there is mention of a "mixer" for doing that. Would that be a
software mixer part of the FA-101 drivers present in Windows? I can't see
any reference to a software mixer in the FA-101 manual.
My problem is that when I plug my ADAM-A7 monitors using balanced cables the
output is too hot and even causes some distortion, when using unbalanced
cables the situation is better but still it feels too hot. The odd thing is
that through the headphones the FA-101 level sounds normal and there is no
distortion. I tested the same monitors with an M-Audio Audiophile and the
level sounds normal. The A7s have volume control labeled from -60db to 6db
with 0db at twelve o'clock. Using the FA-101 I can't go pass -30db (using
balanced or unbalanced cables). With the audiophile I can go up to 0db and
sounds fine.
I'll appreciate any help on this since I'm in the middle of several
projects.

ldd loads the wrong library for the test-volume program. It loads the
current installed libfreebob library (e.g. installed in /usr/lib or
/usr/local/lib). Try to set the LD_LIBRARY_PATH environment variable.
e.g for bash:
$ export LD_LIBRARY_PATH=/home/hector/Desktop/libfreebob/src/.libs
$ ./test-volume 0 5 -1000
Then ldd should find the correct library. If that works you could
overwrite the installed libfreebob version with your own compiled

Yes this mails is still true. Though to be honest I have never tried it
really. I've just implemented the program and looked at the responses

IRC, the FA-101 is the only device in the BeBoB family which has a very
simple mixer implemented. I can't really tell what you can do with it.
There is a schematics drawn on the device top. Maybe that gives you a
clue what the built in mixer can do.

Installing manually into default locations without un-installing the systems
package *will* break things. And even then you need a way of telling the
system to not overwrite your installed package with the systems one again.
So its far easier to install you custom freebob (and possibly jack) in your
home-dir and have the LD_LIBRARY_PATH set up in your .profile or .bashrc...

Pieters plan is to ditch OSC and introduce DBUS. With that it will be possible
to write small apps that control the devices mixers. (As the python-apps in
support/mixer do for some devices already.)
The test-programs should be ditched before the release imho...

Got it working, but it seems that there is no way to control the outputs.
Using any value higher than 5 as the FB_ID just returns zeros, e.g.
$ ./test-volume 0 6 -32768
max volume value = 0
min volume value = 0
old volume value = 0
new volume value = 0
The only way to reduce the output is by turning the MIX knob on the front of
the interface, but that actually is just a balance between the inputs and
the outputs, so then because the output level is still high, as you turn the
know towards the inputs the output level gets reduced but it is replaced by
the over amplified noise of the inputs. I'll try to find a way of testing
the interface with Windows and see what the behavior is.
Thanks for your help!

A pair of XLR in-line attenuators will be much cheaper !
But I'm convinced that all this is a non-problem if looked at
in the right way. Consider this:
When using active speakers connected directly to the sound card,
you want to adjust the individual speaker gains once and then
forget about them - they are not meant as a 'volume control'.
In that case you adjust the gains of the monitors in such a way
that a full scale signal from the soundcard produces the _maximum_
_peak_ volume that you will ever require. This will be much higher
than the normal listening level, typically 30 dB or so higher.
In such a system you don't have a master volume control in hardware,
so you need to provide one in software. All applications then should
connect to the app providing this master volume control instead of
to the soundcard directly.
In other words, you don't try to use the full range of the sound
card all the time. If it's 24-bit and good quality there's nothing
wrong with that.
Imagine that your speakers would have a digital input. That would
create exactly the same situation - the average digital level you
would send to them would be quite low.
In this case, consider the software side of your soundcard to be
the digital input of your speakers. Then it becomes entirely
logical to put the volume control before the soundcard, i.e. in
software.

New subject: Categorizing Ladspa plugins?
Hi list,
I've got a short question: How can I categorize my Ladspa plugins? I've
installed a lot of plugins to be able to choose the ones that are right for
me, and now it's getting a little bit messy. If I want to chain a plugin, for
example in ardour, quite 50% are categorized, but the other half is
uncategorised. How can I assign them a category? Thanks for your advice!

Hi Matthias
LADSPA plugins are categorised using RDF files - you can usually find them under
/usr/share/ladspa/rdf (or do
$ echo $LADSPA_RDF_PATH)
in case they're installed somewhere else on your distro)
Plugins that aren't categorised lack a description in one of these files, and your
best bet would be to write them up yourself. You can get away with copying the header and
root element from one of the other files:
---8<---
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE rdf:RDF [
<!ENTITY rdf "http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<!ENTITY rdfs "http://www.w3.org/2000/01/rdf-schema#">
<!ENTITY dc "http://purl.org/dc/elements/1.1/">
<!ENTITY ladspa "http://ladspa.org/ontology#">
]>
<rdf:RDF xmlns:rdf="&rdf;" xmlns:rdfs="&rdfs;"
xmlns:dc="&dc;" xmlns:ladspa="&ladspa;">
</rdf:RDF>
--->8---
and then add an entry for each plugin you want to categorise inside the root element (just
before '</rdf:RDF>') - you'll only need to add three lines for each
plugin - e.g:
<ladspa:OscillatorPlugin rdf:about="&ladspa;1641">
<dc:title>Bandlimited Sawtooth Oscillator</dc:title>
</ladspa:OscillatorPlugin>
The ID (1641 in the example above) and title you can get using the analyseplugin utility
that comes with ladspa. The availbale categories (OscillatorPlugin etc) are found in
$LADSPA_RDF_PATH/ladspa.rdfs
Hope this helps!

Oh - just to add: plugins from the CMT set aren't always installed with their RDF
file, but Steve Harris wrote one:
http://plugin.org.uk/lrdf/cmt.rdf
which you can just drop into that RDF folder, which will save a lot of work :)

From the README:
--------------------------------------------
AMB-plugins-0.3.0 Released 2007.08.27
--------------------------------------------
* Two new plugins added, both second order horizontal
and first order vertical (i.e. six channels).
1979 2nd order Mono panner
1980 2nd order Rotator
* New name scheme introduced, using two numbers:
a,b means horizontal order 'a', vertical order 'b'.
* Plugins are now organised in two files:
ambisonic1.so : first order (6 plugins)
ambisonic2.so : second order (2 plugins)
The install target in the Makefile will remove any
older versions. If you have saved host configurations
(e.g. Ardour sessions) using any of these plugins you
may have to remove and re-insert them.

Thank you Fons for your commentaries,
I thought about the software option so that's why I've been unsuccessfully
trying to build jack_mixer (I have to build from SVN but there is no
autogen.sh script and autoconf is not working). I like the fact that
jack_mixer has midi control so I can use a external midi controller to
change the levels... but the problem is that if I lower the volume on the
software side and I increase the level on the monitors, then I start hearing
a lot of noise mixed with the (now lower) sound signal (since the analog out
of the FA-101 is still high). This is why I thought an analog mixer between
the FA's outs and the monitors would be better. I researched the XLR
attenuators and I found that paying for two of those (around $35CAN each)
has a higher price than a small mixer (e.g. the Behringer XENYX 502 for
$57CAN), but maybe there are cheaper attenuators around, I'll take a look
(thanks for telling me about them, I didn't thought about it).
If the software solution was the right one, it would be nice if Qjackctl had
a simple mixer for the outputs that remembered settings so each time you
start it you don't have to worry about opening another mixer application and
dealing with all the software connections... but I guess I could just have a
script that runs each time Jack is started.
Cheers!

well... tested in Windows and the level is as
high as in Linux. There is
no
Edirol control panel or software mixer to lower
the levels in the
interface.
I guess I'll have to get a mixer.
A pair of XLR in-line attenuators will be much cheaper !
But I'm convinced that all this is a non-problem if looked at
in the right way. Consider this:
When using active speakers connected directly to the sound card,
you want to adjust the individual speaker gains once and then
forget about them - they are not meant as a 'volume control'.
In that case you adjust the gains of the monitors in such a way
that a full scale signal from the soundcard produces the _maximum_
_peak_ volume that you will ever require. This will be much higher
than the normal listening level, typically 30 dB or so higher.
In such a system you don't have a master volume control in hardware,
so you need to provide one in software. All applications then should
connect to the app providing this master volume control instead of
to the soundcard directly.
In other words, you don't try to use the full range of the sound
card all the time. If it's 24-bit and good quality there's nothing
wrong with that.
Imagine that your speakers would have a digital input. That would
create exactly the same situation - the average digital level you
would send to them would be quite low.
In this case, consider the software side of your soundcard to be
the digital input of your speakers. Then it becomes entirely
logical to put the volume control before the soundcard, i.e. in
software.

Still this is not normal. The nominal output level of the FA101 is
+4dBu, nothing special, with a S/N ratio of over 100 dB. The maximum
SPL of the ADAM A7 is somthing like 105 dB, so even if its nominal
input level is 20dB lower than the output of the FA101 the noise
level should be 25dB, which is imperceptible even in a very quiet

Hello Fons,
Yeah, I can't understand what's going on. The odd thing is that I tried with
different monitors (Roland DM-20) and the signal level seems fine, a little
high but not as dramatically high as with the ADAMs... I have no idea what's
going on. I just got response from Edirol's support and their only
suggestion is to use a mixer (and the mention the +4dBu nominal output).
I'll try now contacting ADAM's support.
Cheers,
Hector

Provided the inputs work and can be more or less calibrated,
that should be easy enough to verify using JAAA.
