Custom browser - custom preset file format???

[Orvillain]

woohoo! I've now got a custom FX chain file format too. At least in prototype form.

I think I'll write a tutorial on all of this once I've properly sussed it all out. Because it is quite powerful, and no-one else really seems to have dove into this.

I have :)

Battling a little with extension issues however.

@Christoph-Hart When saving a user preset am I stuck with the .preset extension??

No one else with the time to do a tutorial example ;-)

Seemed pretty trivial really - its just taking the values you have assigned to params of a given FX and encoding those with the FX name in a json object...

Cool, thanks for the help.

Here's a handy line:

        FileSystem.getFolder(FileSystem.UserPresets).getChildFile("FXChains").getChildFile(PluginSharedData.lastSavedFXChainFileName).move(FileSystem.getFolder(FileSystem.UserPresets).getChildFile("FXChains").getChildFile(PluginSharedData.lastSavedFXChainFileName.replace(".preset", "")));

I've got this in the post save callback. It's job is to take the FXchain file I just saved, and rename it to take off the .preset extension that HISE automatically adds whenever you use Engine.saveUserPreset command.

So now I can save two types of user preset: a global state preset, with a .preset extension... and an fxchain preset that collects module information for each of my FX slots, UI parameters, and bundles it all up into a .fxchain preset.

@Orvillain You can simplify your chain by including multiple directory levels in the .getChildFile calls.

Ohh, more like this I guess?

const base = FileSystem.getFolder(FileSystem.UserPresets);

base.getChildFile("FXChains/" + PluginSharedData.lastSavedFXChainFileName)
    .move(
        base.getChildFile(
            "FXChains/" +
            PluginSharedData.lastSavedFXChainFileName.replace(".preset", "")
        )
    );

??

@Orvillain Yeah that's it! I'd break it up a little more to improve the readability and to remove some repetition.

const presetDir = FileSystem.getFolder(FileSystem.UserPresets);
const filePath = "FXChains/" + pluginSharedData.lastSavedFXChainFileName;
const file = presetDir.getChildFile(filePath);
const target = presetDir.getChildFile(filePath.replace(".preset"));

file.move(target);

You could simplify it further by using .rename instead of .move

const presetDir = FileSystem.getFolder(FileSystem.UserPresets);
const file = presetDir.getChildFile("FXChains/" + pluginSharedData.lastSavedFXChainFileName);

file.rename(file.toString(file.Filename).replace(".preset"));

@David-Healey I'll implement that a bit later on. Right now I'm trying to figure out why when I load my fxchain "user preset" it peforms a full state reset!

updateSaveInPresetComponents

I think it is this call.... I'm willing to bet it has a default fallback mechanism where it resets controls to default, if it isn't specified in the data you feed it.

So I change my FXchain load mechanism to iterate over the components manually.
