@Morphoice I found the solution some time ago in the code of a plugin from @oskarsh. You have to copy the .cpp and .h files of the plugin from Airwindows into the folder .../DspNetworks/ThirdParty/src (actually any path works but as far as I know this is the one Hise intended). Using Tube2 as an example, this is Tube2.cpp, Tube2.h and Tube2Proc.cpp.

In the same directory you must also place the file AirWindows.h:

#pragma once

#include <set>
#include <string>

#include <JuceHeader.h>

    }

You must then save the file Tube2.h in the directory .../DspNetworks/ThirdParty. In this file you have to set the paths to the files in the src folder and define the name, in this case Tube2, in several places. This is also the only file you need to edit if you want to include another Airwindows plugin:

#pragma once

#include <JuceHeader.h>

#include "src/AirWindows.h"

namespace airwindows::tube2_ns {
JUCE_BEGIN_IGNORE_WARNINGS_GCC_LIKE("-Wmultichar")
#include "src/Tube2.h"

#include "src/Tube2.cpp"
#include "src/Tube2Proc.cpp"
JUCE_END_IGNORE_WARNINGS_GCC_LIKE
}  // namespace airwindows::tube2_ns

namespace project {

using namespace juce;
using namespace hise;
using namespace scriptnode;

DECLARE_AIRWINDOWS_NODE(Tube2, tube2_ns);

}  // namespace project

And that's it. Then start Hise and press Compile DSP networks as DLL. This has worked for me for several (rather simple) Airwindows plugins.

@mmprod A few days ago I made a pull request to update the documentation.:

Instead of pathIcon, one of the following standard cursors can also be used as a string:

// Changes the mouse pointer over the ScriptPanel1 to a hand with a pointing finger
ScriptPanel1.setMouseCursor("PointingHandCursor", Colours.white, [0, 0]);

I also wanted to draw attention to this problem, except that I don't have such good proof, only my auditory impression. The resonance of the SVF LP, despite a Q of 0, is clearly audible. And just like the ladder filter, the Moog filter also makes the signal significantly louder overall.

I also noticed that the SVF BP and Notch Filter display in Scriptnode is broken.

(Is the forum actually the right place for bug reports?)

I recently released my first plugin (nothing special, the code is not the best) and on a user's Linux the plugin could not be opened with the following error message:

X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 20 (X_GetProperty)
Resource id in failed request: 0x0
Serial number of failed request: 54
Current serial number in output stream: 54
Scan Failed.

While researching, I came across this known bug in Juce 6.3.1 which, if I understand correctly, is the Juce version that Hise uses. So I manually imported the patch into the Juce code that comes with Hise and recompiled Hise and my plugin. And indeed, this fixed the error and the plugin could be loaded.

Perhaps this is also of interest to someone here. It would be amazing if @Christoph-Hart could import the patch directly into the Hise version of Juce.

@HISEnberg @ulrik Yes, but please be aware that I am only a amateur. I hope that people who are really familiar with it will intervene here if I have described something incorrectly or badly.

SNEX nodes and C++ nodes look very similar and work almost the same. If you create a C++ template under ‘Tools -> Create C++ third party node template’ and view the C++ file in an editor, you will see that the basic functions correspond to those of the SNEX node. I have essentially just copied the code from the SNEX node into the respective functions of the C++ node.

When doing this, you must pay attention to the following:

• The variables declared in the function header must be named as they are used (for example, sometimes data and sometimes just d)
• The conversion of the data to FrameData in the process function must happen as it is already in the C++ template (I don't know why).

Specific C++ node specifications must then be made. In the ‘Metadata Definitions’ at the top, static constexpr int NumAudioFiles = 1 must be set, as we want to play an audio file. In addition, the ‘Play’ knob must be created in the createParameters function at the bottom.

Once all this is done, the node can be compiled via ‘Export -> Compile DSP networks as dll’. After restarting Hise, the SNEX node in ‘Script FX1’ can be replaced by the C++ node. The entire Scriptnode can then be compiled.

Here is my C++ Node version of the SNEX simple_player:

// ==================================| Third Party Node Template |==================================

			ed.setDisplayedValue((double)currentIndex);
		}
	}
	
	int handleModulation(double& value)

@ulrik I got it to run by transferring my snex code into a third party c++ node.

@ulrik Have you found a solution for this? I am currently getting the same error.

@d-healey Ok, I have found out. There are two compilerSettings.xml files on my computer. One in .config/HISE which is the wrong one and one in my home folder in .hise (the right one). Thanks for the help!

@Morphoice I have only compiled it on Linux so far.

@Christoph-Hart Two tick marks in a combobox popup. This has already been mentioned here somewhere. A screenshot and a snippet are in the GitHub issue.

@Morphoice I tried it with my plugin and was able to compile it in my Windows 10 VM with Visual Studio 2022 without any problems.

@Morphoice I have only compiled it on Linux so far.

@Christoph-Hart Oh, great, I didn't know that existed.

@Morphoice I found the solution some time ago in the code of a plugin from @oskarsh. You have to copy the .cpp and .h files of the plugin from Airwindows into the folder .../DspNetworks/ThirdParty/src (actually any path works but as far as I know this is the one Hise intended). Using Tube2 as an example, this is Tube2.cpp, Tube2.h and Tube2Proc.cpp.

In the same directory you must also place the file AirWindows.h:

You must then save the file Tube2.h in the directory .../DspNetworks/ThirdParty. In this file you have to set the paths to the files in the src folder and define the name, in this case Tube2, in several places. This is also the only file you need to edit if you want to include another Airwindows plugin:

#pragma once

#include <JuceHeader.h>

#include "src/AirWindows.h"

namespace airwindows::tube2_ns {
JUCE_BEGIN_IGNORE_WARNINGS_GCC_LIKE("-Wmultichar")
#include "src/Tube2.h"

#include "src/Tube2.cpp"
#include "src/Tube2Proc.cpp"
JUCE_END_IGNORE_WARNINGS_GCC_LIKE
}  // namespace airwindows::tube2_ns

namespace project {

using namespace juce;
using namespace hise;
using namespace scriptnode;

DECLARE_AIRWINDOWS_NODE(Tube2, tube2_ns);

}  // namespace project

And that's it. Then start Hise and press Compile DSP networks as DLL. This has worked for me for several (rather simple) Airwindows plugins.

@Christoph-Hart Shape FX shows no graph except for 'Curve':

Shape FX shows no graph except for 'Curve' · Issue #712 · christophhart/HISE

Except for the ‘Curve’ algorithm, the Shape FX module does not display a graph of the waveshaping function.

@CyberGen I have the same problem on Linux.

@HISEnberg @ulrik Yes, but please be aware that I am only a amateur. I hope that people who are really familiar with it will intervene here if I have described something incorrectly or badly.

SNEX nodes and C++ nodes look very similar and work almost the same. If you create a C++ template under ‘Tools -> Create C++ third party node template’ and view the C++ file in an editor, you will see that the basic functions correspond to those of the SNEX node. I have essentially just copied the code from the SNEX node into the respective functions of the C++ node.

When doing this, you must pay attention to the following:

• The variables declared in the function header must be named as they are used (for example, sometimes data and sometimes just d)
• The conversion of the data to FrameData in the process function must happen as it is already in the C++ template (I don't know why).

Specific C++ node specifications must then be made. In the ‘Metadata Definitions’ at the top, static constexpr int NumAudioFiles = 1 must be set, as we want to play an audio file. In addition, the ‘Play’ knob must be created in the createParameters function at the bottom.

Once all this is done, the node can be compiled via ‘Export -> Compile DSP networks as dll’. After restarting Hise, the SNEX node in ‘Script FX1’ can be replaced by the C++ node. The entire Scriptnode can then be compiled.

Here is my C++ Node version of the SNEX simple_player:

@ulrik I got it to run by transferring my snex code into a third party c++ node.

@ulrik Have you found a solution for this? I am currently getting the same error.
