Hi all,
I am trying to wrap my head around the OSC interface to FAUST and am trying
to get the noise.dsp from the examples to respond to OSC messages. I have
tried sending it things like "/hello" and "/1/slider1 s
'hello'" and
"/hello f 1.0" on port 5010 while listening on 5011 and 5012 to no avail. I
must be completely missing something here but what exactly am I supposed to
send when it says "a hello message" in the docs? Could someone just go
through all the simple steps of an OSC "hello world" in FAUST?
Kind Regards,
Kaspar

Sorry i meant ports 5510, 5511 and 5512 , I did get this right when
actually doing it.

Hi Kaspar,
For hello and get you should send :
/* s "hello"
/* s "get"
Assuming "noise.dsp" is running, you will receive
/noise 192.168.1.105 5510 5511 5512
and
/noise/Volume 0.5 0 1
Sending
/noise/Volume f 0.8
will set the volume of noise.dsp to 0.8
Cheers
Yann

Thanks for the help Yann. I think that could be made clearer in the docs,
the exact message you are supposed to send for idiots like me.
Anyway, I don't seem to be getting any response from it.
I compiled noise.dsp to a jackgtk application and I am using the oscsend
and oscdump utilities provided by liblo.
I tried all of these without success:
oscsend localhost 5510 "/*" s hello
oscsend localhost 5510 "/*" s get
oscsend localhost 5510 "/a" s get
oscsend 127.0.1.1 5510 / s hello
oscsend 127.0.1.1 5510 / s get
oscsend 127.0.0.1 5510 "/a" s get
oscsend 127.0.0.1 5510 "/*" s get
oscsend 127.0.1.1 5510 "/*" s get
oscsend `hostname` 5510 "/*" s get
.
.
.
Could it be because the wildcard expansion isn't supported by liblo? Am I
supposed to do something special at compile time?
Cheers,
Kaspar

The documentation can certainly be improved and questions are very helpful for that.

OSC support is an option available on some Faust architectures. To activate this option
with faust2xxx scripts you need to use the flag -osc. Try for example :
faust2jack -osc noise.dsp
When you start ./noise you should see several messages on the standard output, in
particular :
Faust OSC version 0.91 application 'noise' is running on UDP ports 5510, 5511,
5512
indicating that the OSC support is active and the UDP ports used.
Cheers

faust2jack -osc noise.dsp
OK! Now we are getting somewhere.
When you start ./noise you should see several messages on the standard
output, in particular :
Faust OSC version 0.91 application 'noise' is running on UDP ports 5510,
5511, 5512
Nothing of that sort on stdout. I do get that sort of message as OSC on
port 5511.
While I have you on the line here. Did you see my other question about
MIDI? I would be really interested to learn how easy it would be to do a
direct MIDI output using FAUST and a little example would go a long way I
think.

This probably means that you are using a pre-osc version of Faust. Try to update to the
git version.

You can have a look at Albert Gräf faust-lv2 project http://code.google.com/p/faust-lv2/,
a Faust architecture for LV2 Audio and MIDI Plugins.

Thanks a lot for your help.

version of Faust. Try to
update to the git version.
Will do, would you recommend the faust or the new faust2 branch?

I did look at faust-lv2, the problem is it seems to be for MIDI to Audio
rather than Audio to MIDI which I am interested in as I would like to write
a drum triggger/replacer type application.

Oops, I misread that, too. I remember writing a little helper object for
Pd which triggers control messages for nonzero sample values in its
audio input. Once you have that, you can easily map that to a MIDI
message in Pd, so you might be able to use that for your purposes. The
object is called bit~ and is contained in this tarball:
http://prdownloads.sourceforge.net/q-lang/kcs-example.tar.gz
Of course, you then still need to write a Faust program which computes
the trigger pulses from its input, so that you can pipe the output
signal from that unit into bit~.

Cool! I will take a look at this just for reference. I guess I will have to
make my own way from there as graphical programming gives me the
heebie-jeebies.

That's not standalone, though, it needs an LV2 host and is coded as an
LV2 plugin. You could probably use the voice allocation algorithm and
the mapping of notes to Faust control variables, though.
I also have an example of a standalone Faust MIDI synthesizer, but it's
written in Pure, so probably not that much help if you want to do it in
C++. But I can send it if you want.
