Restoring properties with DAW session

d.healey

@Christoph-Hart Is there any chance of getting a feature so we can have controls stored with the DAW session but not in the preset?

One important use case I can think of is a plugin's master volume control. The user sets this to their desired level and then goes exploring different presets, of course the volume level stays the same. But then when they later reopen their session suddenly the volume level is back to default and blows out their ears :) (ask me how I know...)

Christoph Hart

No this is rather unlikely as it will complicate the data model for a pretty narrow use case.

What I would do in this scenario is to set the master control slider saveInPreset = true, then have a "Master volume lock" button (which is saveInPreset=false). and a user preset post callback that sets the master volume back to the stored value if the lock button is enabled (grab the master volume value that you want to load in the button callback).

d.healey

@Christoph-Hart My current solution is to write the value to a file and read it back in to the saveInPreset=false control. This works but is global so all instances of the plugin will end up with the same value, even if they had different values when the DAW was closed. If I understand correctly your suggestion will have the same issue?

d.healey

Oh I just re-read your suggestion, I think that will work, I'm not sure the lock button is necessary

Christoph Hart

My current solution is to write the value to a file and read it back in to the saveInPreset=false control

Isn't that saveInPreset=true with extra steps?

And in my scenario the lock button is necessary, or you can just set saveInPreset=true for the master volume, no?

d.healey

@Christoph-Hart I'll play around with it and report back :)

@Christoph-Hart

I just want to check I'm doing this the way you meant

With this setup I have to add a new button to the UI and the user has to click it every time they adjust the knob. If I have unrelated components on the UI that require this system I'll need to have multiple lock buttons that the user has to click. Also the knob's callback will still be triggered when the preset is changed so I have to add extra checks there. Am I understanding this correctly?

@Christoph-Hart
I would really like this kind of feature (save in DAW, but not in preset)! I would also need a preset pre/post-save callback function for the project I am working on.
I see you have added this function (UserPresetHandler.setUseCustomUserPresetModel()) that seems to give us control over the load and save callbacks.
Could you please give us a little more details on how to correctly use this?
How can we differentiate between preset and DAW save data with this save/load callback? Would functions like updateSaveInPresetComponents() and updateConnectedComponentsFromModuleState() still work with this?

d.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();
	 }
    });

Christoph Hart

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.

d.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.

d.healey

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

d.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).

d.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:

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

d.healey

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

d.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:
