Faust support

Oh ok I will have a look at this workflow. The one explained in the wiki works fine

Concerning OSC support: we were using OSCServer and OSCClient classes. It seems there were just completely removed ? What are the replacement ?

@doconnell have fixed the OSC code? It yes then I'am interested to integrate the new code in Faust GitHub repo.

For MIDI support, you'll have to use the "bela-midi" target, or "bela-midi-polyxx" in the Faust IDE.

The OSCClient and OSCServer classes had long-standing problems, so we replaced them with OscSender and OscReceiver. See the examples Communication/OSC and Communication/OSC-Pipe to get a taste of how the new classes work. I can start drafting this if I understand how to test the OSC in FAUST

The current code is there: https://github.com/grame-cncm/faust/blob/master-dev/architecture/faust/gui/BelaOSCUI.h
A running Faust DSP compiled with OSC supposed uses (by default) an 5510 input port and 5511 output port (see the main architecture file here : https://github.com/grame-cncm/faust/blob/master-dev/architecture/bela.cpp)

Hopefully @RPA can have a look on the code in a few days.

Hi,
Very sorry, I'm too buzy to work on it :-(

I'm trying to see what can I do, but the new Library is completelly different. And so BelaOSCUI must be changed completelly. I'm a too bad programmer to do it fast… and clean!
And according to the 2 example, I'm not sur which solution using. (with or without "pipe").

Anyway, I can test it, I have all the time a BELA near me !

RPA And according to the 2 example, I'm not sur which solution using. (with or without "pipe").

If you NEED to process the incoming OSC in the audio thread, then you should use the one with the pipe. If you are happy to process them in a different thread, then the one without pipe should work.

I will do my best to find the time to attempt a fix before the end of the week, I think

Hi giuliomoro, is this thread sort of a response to my earlier thread, or just an ongoing thing about OSC?

https://forum.bela.io/d/1070-status-of-faust-on-bela

This is an ongoing thing about OSC yes. @giuliomoro I've just sent @RPA a reworked piece of code to test. Stay tuned.

Hi,
I'm testing code of Stephane.
We have a small problem:

/root/Bela/projects/OSCtest/render.cpp:6348:61: error: too many arguments to function call, expected 2, have 3
fReceiver.setup(fInputPort, oscMessageReceived, this);

So it looks like fReceiver.setup need only 2 args (as the BELA example), but the documentation write that it need 3 args. Where is the error ?

(I would like to add files, but it looks like the attach button doesn't works, .cpp or .h files; or .zip ?)

giuliomoro

Can you push the file to GitHub somewhere and paste a link?

RPA So it looks like fReceiver.setup need only 2 args (as the BELA example), but the documentation write that it need 3 args. Where is the error

It looks like you have an old version of the code on the board. OscReceiver::setup() takes up to three arguments since bb6abc3 (4 Oct 2019)

RPA

Ok, no. I didn't update bela since my 1st test of the new version.
I'll test it

RPA

With updated version, it works better ;-)
There is just a small problem, but in the FAUST side of the code...
All should be corrected soon!

OSC and MIDI is now fixed in GitHub master-dev branch: https://github.com/grame-cncm/faust/commit/c2a6f90c50b1815e0e9d8eddcaec8640148856a4

Thus the fix in still not in the online compiler. If you want to test it, you'll have to install Faust on your machine. Otherwise you'll have to wait a few days more.

giuliomoro

Great! Instructions for installing faust on your computer and use it with Bela: https://github.com/BelaPlatform/Bela/wiki/Compiling-Faust-code-for-Bela

Bela target updated in online compiler: https://faust.grame.fr/ide/
