Guidance building for Bela platform

weefuzzy · July 21, 2022, 2:27pm

@a.harker yes, convolution tools is on the way out. I’m about to attack transients again (on an allocator rampage), and will fold in the changes we did a while ago.

@jarm I think it’s only the transients objects that will be broken. I don’t think they’ll run happily on Bela in any case at the moment because they’re very CPU heavy (I plan to try and improve this). My advice would be to simply remove them from the build altogether.

You can remove the targets by going to build/__deps/flucoma-core-src/FlucomaClients.cmake and commenting out all the add_client calls with transient stuff (lines 118, 119, 138, 139 on my working branch). Then re-run CMake.

a.harker · July 21, 2022, 2:29pm

On the public version SineExtraction.hpp also includes ConvolutionTools.hpp, but it doesn’t actually use it…

weefuzzy · July 21, 2022, 2:36pm

Does it still? I keep meaning to take it out. Yeah, that include can just be zapped (although Sines might also be a bit chunky for the Bela, we’ll see).

jarm · July 21, 2022, 4:17pm

Commented out the Transient objects, removed the include of ConvolutionTools in SineExtraction, and it finally built:

Haven’t had time to test yet!

weefuzzy · July 21, 2022, 5:26pm

Woohoo! Thanks so much for persevering!

tremblap · August 9, 2022, 9:18am

@jarm let us know how it actually performs - this is a beautiful new set of possibilities you are opening there! Thanks as usual to @a.harker for his benevolent help

a.harker · August 15, 2022, 10:46pm

As an update I’ve been working on SIMDSupport.hpp today and I have a local copy that is both aarch64 and arm happy. I’ve pushed all the 64 bit stuff to HISSTools_Library already, but for the 32 bit stuff I want to neaten up a bit. Anyway - that should now be more reliable for various arm situations pretty soon.

jarm · October 14, 2022, 2:12pm

Finally given this a quick go, and it seems that Bela’s libstdc++ isn’t up to date enough for Flucoma:

jarm · October 14, 2022, 3:07pm

Ok, looks like we have liftoff! Tried the following:

s = Server.default;

s.options.numAnalogInChannels = 2; // can only be 2, 4 or 8
s.options.numAnalogOutChannels = 2;
s.options.numDigitalChannels = 16;
s.options.maxLogins = 4;  	   // set max number of clients
s.options.bindAddress = "0.0.0.0"; // allow anyone on the network connect to this server

s.options.blockSize = 256;
s.options.numInputBusChannels = 2;
s.options.numOutputBusChannels = 2;

s.waitForBoot{
	SynthDef('FluidPitchTest', {
		var freq, conf;
		var in = SinOsc.ar(440);//SoundIn.ar(0);
		# freq, conf = FluidPitch.kr(in,window:1024);
		freq.poll(0.5);
		conf.poll(0.5);
	}).add;

	s.sync;

	f = Synth('FluidPitchTest');
};

ServerQuit.add({ 0.exit }); // quit if the button is pressed

Which outputs:

UGen(OutputProxy): 442.103
UGen(OutputProxy): 0.939491
UGen(OutputProxy): 442.104
UGen(OutputProxy): 0.939481

This consumes around 32% CPU, compared to 8% without the SynthDef or Synth. It is sensitive to block size and window size: block size <256 seems to be nothing but underruns for FluidPitch at least.

I’m going to keep puttering about on this, if anyone fancies cooking up a little benchmark script that checks across the various UGens or something I would be happy to run it.

jarm · October 14, 2022, 3:15pm

FYI, on the latest version of Bela you will need to copy your installation to the following directory (symbolic links will fail):

cp -r /path/to/release-packaging/FluidCorpusManipulation /usr/share/SuperCollider/Extensions/FluidCorpusManipulation

I am starting to document things here: GitHub - jarmitage/flucoma-bela: Experiments combining Flucoma with Bela

weefuzzy · October 14, 2022, 9:15pm

Great – thanks for pushing through. Delighted that it builds and runs, though 32% is pretty chunky

Which branch are you on? What’s on dev at the moment may give an improvement over main, as it makes better (i.e. some) use of the SC real-time allocator, and also updates the HISSTools dependency to take advantage of SIMD fixes (and gets rid of that rougue header from before).

jarm · October 16, 2022, 8:05pm

Oh nice, sounds like it might be worth another build then! I’m still currently on main from whatever state things were in in July. Anything else coming in the very near future that I should wait for?

I am also kinda curious about compiling the flucoma core and using that in Bela C++ programs, and also trying to get the Pd version going on Bela too… Fun times ahead

jarm · November 15, 2022, 12:04pm

I am trying to update the builds based on flucoma-sc dev branch:

Any idea what’s happened here?

weefuzzy · November 15, 2022, 12:17pm

Hmm. Perhaps CMake didn’t change the branch for flucoma-core, which would be weird and annoying.

If you re-run cmake:
cmake ..
does it sort itself out?

You should see it pulling in some new dependencies

jarm · November 15, 2022, 12:51pm

Running cmake again doesn’t pull in anything, presumably since it believes it already has what it needs, I assume you mean to do it from scratch?

Also seeing this Python error:

weefuzzy · November 15, 2022, 12:56pm

Don’t think the Python error is connected. I’ve seen it before, but can’t remember quite why just at the moment.

Meanwhile, can you do ls _deps? That might help gauge how wrong things are going

If I git checkout dev then the missing file is there, but then I have to re-run cmake from scratch again due to GLOB mismatch!

Very painful and slow since sharing network with Bela over USB, and using the distcc compiler, are incompatible unless you update all of the IP addresses :')

weefuzzy · November 15, 2022, 1:14pm

Ah, sorry, brain fart on my part.

To get flucoma-sc to pull in a specific branch of flucoma-core and flucoma-docs try

cmake -DFLUID_BRANCH=dev ..
