Adventures in ScriptNode - Faust (part 2)

[Lindon]

Okay so I got jpverb up and running from Christophs code - so I thought I'd start out with something with few params so I decided to give ef.transpose a go...

heres my code:

// Faust Source File: FaustPitch
// Created with HISE on 2022-12-02
import("stdfaust.lib");

// w : window length in samples
w = hslider("Window", 512, 256, 8192, 1);

// x: crossfade duration (samples)
x = hslider("crossfade", 512, 256, 2048, 1);

//s: shift (semitones)
s = hslider("Pitch", 0, -12, 12, 1);

process = ef.transpose(w, x, s);

and when I try to compile it tells me:

undefined symbol : transpose

hmm...its defined just like this in the library: https://faustlibraries.grame.fr/libs/misceffects/

is transpose not in the stdfast.lib ?
do I not understand how this is supposed to work?

[Lindon]

@Lindon ..and its because transpose is a mono processor - or at least I can get it to compile and work using a mono signal...

[Christoph Hart]

Tripping over the channel amount is usually the second thing that everybody does after not getting Faust to compile, maybe I need to make another sticky...

[Lindon]

@Christoph-Hart -= yeah and its not the most helpful of error messages...

[Christoph Hart]

@Lindon this is out of my hands but usually faust complains with a better diagnosis involving the word „channels“

[toxonic]

@Christoph-Hart when i try to compile it, i get an error message regarding channel mismatch, right as i expected...

with

process = _,_:ef.transpose(w, x, s),ef.transpose(w, x, s):_,_;

it should work in stereo. (or with sp.stereoize())

[Lindon]

@toxonic

wouldnt that be:

process = ef.transpose(w, x, s),ef.transpose(w, x, s);

[toxonic]

@Lindon both versions do work in the meantime, when i remember correctly, that wasn't the case in early versions of faust. i just defined input and output channels.
