@Christoph-Hart Still no code output from a Faust node on 2.74, but if I compile the network and load the compiled Faust file (not necessarily the network) from the Projects tab in Scriptnode, it works.

[aaronventure]

@aaronventure Also, no.rnoise doesn't crash HISE anymore, but fails to build as a network Crashes on 2.72 (probably due to arc4random missing).

If I change it to no.noise, it goes through fine.

Again, it works fine on macOS.

[Christoph Hart]

I talked to Stephane yesterday - the API changed from 2.72 to 2.74 so I need to update the HISE wrapper to reflect this.

I could get it to work here but it will break using previous Faust versions, so I need to think whether it makes sense to branch it or just tell people to download and use the lateat Faust version.

This - unless it breaks on older OS versions

[Christoph Hart]

@d-healey I‘m not aware of anything that breaks compatibility with older versions.

Alright then I‘ll move to the latest release and do a check that prints an error message if you use Faust <2.74 - currently it just crashes so that‘s not the world‘s nicest UX.

[Christoph Hart]

OK, so I've pushed the change that switched to Faust 2.74.6 - all older versions stopped working so you need to reinstall Faust if you want to use it.

@aaronventure that should solve all problems with the most recent Faust version, right? I don't care too much about rnoise something something, that's Faust territory :)

Shouldn't you? It works on mac but doesn't on the Windows implementation.

It's a way to get true randomization in Faust because no.noise by default locks to a generated seed, so even if you call it twice or more times, once for each output, you're still getting a mono signal.

If you create two separate Faust files (different files with different names), put them in two different Faust nodes in a multi node, you're still getting a mono output because both are generating from the same seed.

The warning might be a clue but I have no idea what it means.

[Christoph Hart]

@aaronventure yeah, no idea why it crashes and how to solve it. I'm not the Faust maintainer :)

In order to get a stereo noise signal, just multiply it with a random number and then use fmod to fold it back into 0...1

// Faust Source File: rnoisefunk
// Created with HISE on 2024-07-04
import("stdfaust.lib");

// booh! mono
//process = no.noise, no.noise;

// noice stereo noice noice noice
process = fmod(no.noise * 139.2124, 1.0) , no.noise;

[Christoph Hart]

even better:

 // additional delay by 32 samples. 
process = fmod(no.noise * 139.2124, 1.0) , no.noise @ 32;

[aaronventure]

@Christoph-Hart that's still hardcoded and all the node instances of that file will share the seed

but you have me an idea to just link the random node from scriptnode into the faust parameter, so that'll work as the random node gets instanced on startup
