Restoring properties with DAW session

David Healey

Is it possible to add preset pre-processing for when the DAW session is restored?

That way I could do something like this

    presetHandler.setPreCallback(function(presetData)
    {
         for (x in presetData.Content)
	 {
            if (x.id == "knbMasterGain")
	        x.value = knbMasterGain.getValue();
	 }
    });

I'm really trying to prevent giving the user the ability to distinguish between DAW restoring, initial plugin loading and user preset recalling because it creates so many branches with edge cases that are impossible to cover across all hosts.

What are you trying to achieve? If you want to lock the master gain while the user switches presets, you can easily do this with a button that the user has to press before loading the preset, but I remember we already discussed this.

David Healey

@Christoph-Hart Yes we tried that before. But I don't want to add a special lock button for every control that the user wants to preserve with the DAW session but not with the preset, so I'm looking for an alternative. I want it to be a seamless experience for the user, requiring no additional action from them.

Christoph Hart

@d-healey attach a mouse listener to the user preset browser and / or preset load buttons that will deactivate the restoring of any parameter? This makes your entire UI that lock button :)

const var userPresetMouseWatcher = Engine.createBroadcaster({
  "id": "Mouse Watcher",
  "args": ["component", "value"]
});

reg ENABLE_MASTER_LOCK = false;
reg LOCKED_MASTER_GAIN = 0.0;

userPresetMouseWatcher.attachToComponentMouseEvents(["PresetBrowser", "NextPresetButton", "PrevPresetButton"], "Clicks Only", "activate the master gain lock once the user tries to load a preset", function(component, event)
{
    if(event.clicked)
        ENABLE_MASTER_LOCK = true;
});

presetHandler.setPreloadCallback(function()
{
    if(ENABLE_MASTER_LOCK)
       LOCKED_MASTER_GAIN = masterKnb.getValue();
});

presetHandler.setPostloadCallback(function()
{
    if(ENABLE_MASTER_LOCK)
        masterKnb.setValue(LOCKED_MASTER_GAIN);
});

I just typed this out of my head so I'm sure there are some errors, but this should be the gist of it.

David Healey

@Christoph-Hart Aha that's a clever idea. I'll try it, thanks!

David Healey

@Christoph-Hart Yep that works, thank you!

Christoph Hart

Actually I gave in to your constant nagging (JK, I needed it myself now too) so you can use UserPresetHandler.isInternalPresetLoad() which should return true when the DAW restores a preset (and only for the duration of the pre / post load callbacks).

David Healey

@Christoph-Hart Excellent!

@Christoph-Hart Finally got around to testing this.

It works in Reaper on Windows, but not on Linux. Haven't tested on MacOS, Any ideas?

This is my test snippet:

Christoph Hart

@d-healey no idea and precisely the reason why I didn't want to implement this in the first place :)

David Healey

@Christoph-Hart :D I think I'll stick with the previous hack then

David Healey

Turns out the hack doesn't work properly, but I found a solution to the problem I was having with isInternalPresetLoad.

Here is the working version:

I still seem to be having issues with this. Am I going about this the wrong way?

const uph = Engine.createUserPresetHandler();

const var Knob1 = Content.getComponent("Knob1");

reg knobValue;

uph.setPreCallback(function(presetData)
{
	 if (!uph.isInternalPresetLoad())
	 	knobValue = Knob1.getValue();
});

uph.setPostCallback(function(presetFile)
{
	 if (!uph.isInternalPresetLoad())
	 	Knob1.setValue(knobValue);
});

Dan Korneff

@d-healey Have you check that the functions for presetData and presetFile are doing their thing first?

I just looked at my project. I moved the function outside of the Pre/Post callback

	userPresetHandler.setPostCallback(function()
	{
		setMetaData();
	});
	
	inline function setMetaData()
	{
	    //do stuff here
	    
	}

I wonder if I hit the same issue in the past?

David Healey

@Dan-Korneff The functions are being triggered correctly. Inline functions are inlined when the code is compiled anyway so I don't see that making a difference here.

Christoph Hart

@d-healey said in Restoring properties with DAW session:

Inline functions are inlined

Haha, I tricked you with my deceiving naming! Inline functions are not inlined, they just use a better localized scope that doesn't allocate, but it's a function call never the less.

David Healey

@Christoph-Hart I've been living a lie!

But why my code no work?

David Healey

This post is deleted!

David Healey

~~Ahaaaaa it's one of those problems where you don't change anything and magically it starts working!!!~~

David Healey

Mystery solved. I had a default preset set in project preferences. This completely breaks the save in DAW behaviour. Removing the default preset solves the issue.

It would be nice to have both though. On first load we get the default preset, then after that it reverts to the regular behaviour.
