Getting started with Faust for SuperCollider

Development Faust
21

Another cool Faust/SC integration could be to embed the Faust compiler + LLVM JIT compiler in a dynamically programmable UGen (see Embedding the Compiler - Faust Documentation). This has been discussed in the SC community in the past, but never achieved :sweat_smile:

Great idea Stephane! So this in practice would mean you could sort of livecode faust scripts in SuperCollider while using them? Mind blowing!

Wow!! trying to get my head around this one. :grinning:
What excactly means? a sort of generic uGen that can be livecoded? or would the integration still produce a new uGen and therefore the SuperCollider Library has to be compiled anyway?

24

The point is to have live coding yes, as we can do (for years…) in Max/MSP and PureData with faustgen(2). Here is an example of pd-faustgen2 demonstrated at last IFC: 4_Workshop2_Learning and using Faust in the PD environment - A. Gräf - IFC20 - YouTube

Stephane just asked this on the faust list. Anyone have an opinion?

::

Can other SC users give their feeling here?

Thanks.

Thanks for looking into this.

My personal preference would be for the prefix not to be there, since it isn’t there when compiling for other platforms. It makes the UGen names overly verbose, and, if one desires, one can still always name the UGen that way manually by just naming the file accordingly.

The Faust Web IDE interact with the « faustservice » (GitHub - grame-cncm/faustservice), a set of predefined Makefiles that trigger the faust2xx tools installed on the remove compilation machines. So this system is not fully flexible yet.

Thanks Julius. Yes, I have that working correctly. But the online IDE also compiles directly to SC, and for that I don’t know if there is a way to set the options to get rid of the prefix. The max and pd compilers don’t add the prefix. Just the SC one.

When I last used it, faust2supercollider had a -noprefix option.

Is there a way to use the faustIDE to export to supercollider without adding the word Faust in front of the UGen? I imagine this is going with the default of faust2supercollider, but it would be great to be able to turn it off (as you can in the Ruby script). The online IDE is amazing, btw. Thanks for that work.

Agreed - better to omit the prefix

27

Yeah I also agree - let it go :slight_smile:

28

The same here, I agree to let go of the prefix.

Done yesterday on the Faust online compiler, so in particular when using the Faust IDE.

@Stephane_Letz the optimizations you did to the supercollider backend recently has made a big (positive) difference in performance. I see it hasn’t been released yet. Any idea on when it will be put into a release? Thanks!

I am running faust compiled from source so I get all the benefits of this now but I guess others might not have gotten these yet.

31

I am toying around with this today… wish me luck!

I’ve slowly started work on a FaustGen UGen here: GitHub - madskjeldgaard/faustgen-supercollider: A Faust code interpreting SuperCollider plugin

It doesn’t work yet, but it’s got the depencies sorted and I am able to create dsp factories but the actual processing doesn’t work yet, but hopefully I’ll figure this out. If anyone wants to help out, let me know

I’ve made a seperate thread for FaustGen discussions: [WIP] FaustGen - a UGen for interpreting Faust code
