Faust how to make a sound?

[hisefilo]

Hi guys and girls!! I was trying to make a sound out of Faust via HISE, but no luck. A simple oscillator, or any of the examples you can found on the Faust Online IDE (super cool) https://faustide.grame.fr/

Anyone played any sound using MIDI + FAUST within HISE?
What am I doing wrong?

In Faust there is a convention of three parameters that need to be defined in order to control voices

• freq
• gain
• gate

if you define any of these parameters the faust patch will react to MIDI messages (if you put it in a midichain like you already did).

Your snippet doesn't define parameters, so you need to do that yourself. This example should react to MIDI messages accordingly:

// Faust Source File: synth_test
// Created with HISE on 2022-10-31
import("stdfaust.lib");

// define a freq slider (note frequency)
freq = hslider("freq", 200, 20, 20000, 0.1);

// define a gate button (note-on / off)
gate = button("gate");

// define a parameter that will be mapped to velocity (we'll use it for the filter decay time)
gain = hslider("gain", 0.0, 0.0, 1.0, 0.01);

// create an envelope from the gate button
lpEnv = en.ar(0,0.5 * gain,gate);

// create a sawtooth with a LP filter with a envelope modulated by the velocity
osc = os.sawtooth(freq) : fi.resonlp(100 + 1000 * lpEnv,3.0,1.0);

process = osc, osc;

[hisefilo]

@Christoph-Hart Yeah I remember that convention.
Still no sound. It's supposed to do it JIT right?? Or I need to compile DLLs to make it work?

[Christoph Hart]

@hisefilo Please tell me you have pressed F5 to compile that patch :)

[hisefilo]

@Christoph-Hart I don't have F5 LOL. Im on Mac. just clicked this

[Christoph Hart]

@hisefilo Try Fn+F5 :) I haven't added that compile button yet, and this button will just reload the existing code from the text file. 100% brain capacity was used when implementing this feature.

[hisefilo]

@Christoph-Hart Yes already tried after your previous message. Still no sound. Will record a video maybe you can catch what I'm doing wrong

[Christoph Hart]

@hisefilo I'm adding the compile bar like with every other code editor so you have something to click on (it's just an unreasonable amount of code-reshuffling required for that but I'll guess now is the time).

[hisefilo]

@Christoph-Hart

[oskarsh]

@hisefilo I believe you will need to edit the faust code in a external editor or at least make sure it is saved under DspNetworks/CodeLibrary/faust/yourFaustFile.dsp. If your code is in this file you can go ahead to ScriptNode and click the first Icon (two arrows) in the faust node to 'refresh and recompile' the code.

[hisefilo]

@oskarsh Yeaaaa that was it. Was not saving the .dsp
Thank for teaching me! Now I get a no ending sound. But at least note on is working. Will investigate the gate param

[Christoph Hart]

@hisefilo I've pushed a change that adds the compile bar on the faust code editor so you should be able to use it on macOS too.

[hisefilo]

@Christoph-Hart thanks mate. Reporting this!

[hisefilo]

replacing var to bool made it compile. Don't know if it's safe

[hisefilo]

@Christoph-Hart Still not saving the .dsp on DspNetworks/CodeLibrary/faust/
