      Hello, Christoph, I just want to know how to make existing HISE FX effects as dynamic ones. For example, what is the fastest way to get the dynamic IR verb from convolution effect?
      Do I have to make it from scratch?
      And can I pass "{PROJECT_FOLDER}ImpuseResponse.aif" to such dynamic fx as the string parameter?
      I found setStringParameter function disabled, and so I make it available and pass path string to it. But I guess, such file path depends on HISE project folder and I am wondering such file can be loaded while runtime on built plugins.
      Also, I can find some core libraries by loading Libraries.load("core"). And then are they available while runtime not working on HISE Standalone?

        Hi Hasan,

        there is a new Effect Slot module, which is basically a empty shell that can hold a HISE effect. It can load and unload effects dynamically using scripting methods.

        Now for loading impulse responses (or any sort of audio file), you'll need another object type called AudioSampleProcessor (this is a special type of module that handles audio files). It has a method setFile which you can pass the filename.

        This javascript snippet shows the example usage:

        // Get a reference to the slot
const var slot = Synth.getSlotFX("Effect Slot");

const var EmptyButton = Content.addButton("EmptyButton", 10, 10);
Content.setPropertiesFromJSON("EmptyButton", {
  "radioGroup": "1"
});

inline function onEmptyButtonControl(component, value)
{
	// Clears the slot by loading an empty fx
	slot.setEffect("EmptyFX");
};

EmptyButton.setControlCallback(onEmptyButtonControl);

const var Convolution = Content.addButton("Convolution", 170, 10);
Content.setPropertiesFromJSON("Convolution", {
  "radioGroup": "1"
});

inline function onConvolutionControl(component, value)
{
	// This returns a effect object, but we need a 
	// Audio Sample Processor object to load audio files
	local module = slot.setEffect("Convolution");
	
	// This returns the effect as audio sample processor
	// (a special subtype of module that uses audio files like the looper
	// or the convolution reverb
	local moduleAsIr = Synth.getAudioSampleProcessor("Convolution");
	moduleAsIr.setFile("{PROJECT_FOLDER}British.aif");
};

Convolution.setControlCallback(onConvolutionControl);

        This is the full HISE snippet for the example:

        (I've just committed a small fix that allows dynamic creation of audio sample processors, so you need this version for the example to work).

        During development, HISE will use the actual file found in the project directory. In compiled plugins, those audio files will be embedded into the binary and their file reference is resolved internally (unless you opt out of this, then it will look in the AppData folder of the plugin). Now if you compile for iOS, it will just copy the AudioFiles subdirectory in the App bundle and resolve the path correctly, so you shouldn't worry about this.

        BTW, If you're mixing HISE effects with external libraries wrapped into Script FX, I'd recommend to build one ScriptFX per wrapped effect and use the same mechanism with the shells with scripted FX (check out the exportState and restoreState functions of Effect modules which allow you to save whole states including script contents etc..

        The core FX module is available in both HISE and compiled plugins.

          HISE Standalone is crashing when I call setEffect with "ScriptFX". Hope you fix that soon.

            Yupp, I'll take a look (this feature is pretty new and I just made some quick tests with script processors)

              Alright, this is fixed. Let me know if there are more issues, there might be some edge cases with dynamic creation of ScriptFX.

                I am getting some weird thing.
                The effect in effect slot is still working when I set it bypassed. It is bypassed only when I set effect slot bypassed. The bypass button of effect itself does not working.

                  And I want to get the name of effect in Effect Slot, such as "IRVerb" or "Script FX Delay".

                    The Bypass works now.

                    However the ID will be mercilessly overwritten as soon as you change the effect in the slot, so I wouldn't count too much on that information. For which purpose do you need this?

                      I am going to swap effects of slots on runtime. And so I want to know the effect name or type of each slot on runtime.

                        I have tried to change script fx name as customized one like "3BandEQ", and "Save File as XML Backup". Then I can see "3BandEQ.js" saved in "ScriptProcessors" folder.
                        However, when I restart HISE standalone and reload backup XML file I can see all the script fx names become same as "ScriptFX". And when I save file as XML backup again all the script js files are lost except one.
                        Please check these issues.

                            Sorry, I am on the train and internet is terrible.

                            You don't need the IDs for swapping the effects on runtime. Calling SlotFX.setEffect(typeId) returns a reference to the created module. Just store this module and change its parameters using the ordinary scripting methods.

                            This example lets you toggle between a SimpleGain and a ScriptFX with a simple script and lets you control the first parameter from a external slider. It uses the Base64 encoded state feature:

                            /* This is a Base64 exported state:

	1. select the module, 
	2. Edit->Create Base64 encoded state
	3. Paste the string from the clipboard
	
 	This contains the whole state (script, parameter values, etc)
	(actually it's just the encoded XML element)
*/
const var scriptState = "383.3ocYR0sRCCCE9D0JtB5yPoW0AiQ20hHroBhnNVGh2l0dzELKmRRp5T7AY24qiuE9lnIsc5DCgP99NmSx24mwZJGMFRCrcltrDAVXPVtVTZO6V37S9Cb3xRtwfE.iscCIv9LXDoLjD6WpEJaRbignyUBqfKEFtUPp3tGteXXtySazibczEJZVzQQtPsnx1mWT3YRh8mw8hRc6tGFte3cUpbe7QkZrjqwozXIeYhgunThS3VrWzLIk+Pl3Era3qgcBeayXpSsgdGRxmyUJTZ9mWjxqBMISTUKlg5dNAJq940bkkSKDVRmYcemAX6MjJVlMmdRArsCF.2HLhYRrAjQRxeKEHkuBbcI151eRf0zovlZ7W1ezzuT4MkpM9XXzbgrX759mA.XBUYEp6uja0hmAVvUUKxnJcNNpM6cbrs.en03TO1AgLTUTC9xsZMNviYsFGr1Hz1y.2PPqHcxwVO4bP6nRlTTfZP3FT1Mv2Rg5RJv5ri64de0pONF9FXYl+RE";

                              Thanks for your reply.
                              I have one more question.
                              If I use a dynamic library which will be loaded in the plugin or standalone app, then shall I have to add such library file(like .dylib) in the installer?
                              And if so, where should I have to install such library?

                                On OSX, the library must be at

                                Application Support/Company/Product/lib

                                On Windows:

                                %APPDATA%/Company/Product/dll

                                But iOS apps can't use dynamic libraries, so you have to build a static library and link the HISE project with it (this is a bit complicated, but NSK uses this method and it works fine).

                                  I am going to add script fx like following.

                                  But when I make BASE64 encoded state and call restoreState on runtime, HISE freezes and then crashes.
                                  I guess it is because of function "processBlock". If I let it empty then it won't crash.
                                  Please check this issue.

                                    Ah yes, it's a deadlock situation where the audio thread holds the compile lock and the message thread the swap lock.

                                    This is fixed now. However beware the AmpReverb is producing nasty bursts if uninitialised (take a look at the NSK code how I tamed it). Definitely keep your speakers down until you are safe :)

                                    Edit: Set these parameters:

                                    vkfx_ampEq.setParameter(vkfx_ampEq.Volume, 0.5);
vkfx_ampEq.setParameter(4, 0.0); // Reverb Level (enum is defect)
vkfx_ampEq.setParameter(5, 1.0); // Amp Bypass (enum is defect)

                                        Hello, man!
                                        It still crashes when I add the code "vkfx_ampEq >> channels;" in processBlock function.

                                          Is the crash happening if you compile or if you select the effect with the drop down?

                                            It crashes when I compile script.
