@toxonic

I am trying to run the reverbs from here: https://faustdoc.grame.fr/examples/reverb/

But I get the below errors on most of them. How to overcome this?

For example, the below one gives this error:

declare name "zitaRevFDN";
declare version "0.0";
declare author "JOS, Revised by RM";
declare description "Reverb demo application based on zita_rev_fdn.";

import("stdfaust.lib");

process = dm.zita_rev_fdn_demo;

@harris-rosendahl Seems related to this:

@ustk Thank you for the suggestion. I think this duplicating solution doesn't work every time. Maybe because of this is the demo.

This doesn't work

declare name "zitaRevFDN";
declare version "0.0";
declare author "JOS, Revised by RM";
declare description "Reverb demo application based on zita_rev_fdn.";

import("stdfaust.lib");

process = dm.zita_rev_fdn_demo, dm.zita_rev_fdn_demo;

@harris-rosendahl i just took a look at the faust library description in the web, it seems, that this demo has 8 channels....

@toxonic So we can't convert it to stereo? Most of the reverbs give this error on that library page

[toxonic]

@harris-rosendahl
It's always a good idea to check the examples in the Faust Web IDE (just google for it), and have a look at the diagram. There you can see, if you can simply converst a mono channel code to stereo, or if there are other channel issues:

Which reverb for example has a channel mismatch in HISE too?

@toxonic

I see that, thank you so much.

Which reverb for example has a channel mismatch in HISE too?

I've come across this error on reverbTester, reverbDesigner, fdnRev and zitaRevFDN. And as I see in the diagrams, all of them have multiple input channels.

Regarding the JPVerb and Greyhole reverbs, on the Web IDE page the GRAME License has been declared.

But the license of these reverbs has been declared as GPL2+ here: https://github.com/grame-cncm/faustlibraries/blob/master/reverbs.lib

So that means these reverbs can't be used without sharing the source code? So this is not MIT License as @Christoph-Hart shared here: https://forum.hise.audio/topic/6505/faust-is-here/9

I think Licensing is very tricky in Faust :)

[sletz]

Licence of Faust functions in libraries are the choice of the contributors. Some are GPL, some MIT/BSD like...or others. Each function can have its own licensing scheme, which is usually described as a declare licence XXX line (see https://github.com/grame-cncm/faustlibraries/blob/master/aanl.lib#L261 for instance).

@Christoph-Hart Any way to get more than 16 mod sources? My Faust synth needs a lot of them :)
