@Christoph-Hart Thank you dear Christoph
But as a newbie , How we can use the New Feature?

[Lindon]

@Christoph-Hart wow you're on a streak...

The snippet is not working. Nothing happens. can I get an updated snippet?

[DanH]

@Lindon Is it possible to script a 'Save Table Shape' button and a 'Load Table Shape' button for simple porting of shapes between modules in the plugin?

[ustk]

@DanH Could you explain "between modules" please?
If you want other modules to change at the same time you could simply link them
But if you actually want to store different shapes, then you could use exportAsBase64 and restore I guess (never tested)

EDIT: in fact, that was the whole purpose of this thread...

[DanH]

@ustk So for example, if I have two seperate LFOs in a plugin and I want to copy the shape from one to the other one.

I think though what I really want is the ability to save an LFO shape in one instance of a plugin and be able to import that shape into a different instance of the same plugin.

Does that make sense?!

I have been trying to sript the buttons using those API's but I don't quite know how to make it work

[ustk]

@DanH Ok so you have to use the fileSystem and save/restore the base64 shape to/from the external file you've created
https://docs.hise.audio/scripting/scripting-api/filesystem/index.html

[DanH]

@ustk Thanks mate, will take a look! No doubt I will be messaging you again soon! :face_with_tears_of_joy:

[d.healey]

What's wrong with copy/paste?

[DanH]

@d-healey Thanks David, this is great for working within Hise, but I want the User to be able to do the same within the plugin... and even across plugins if possible!

[d.healey]

@DanH @ustk's answer is the way to go then, save the string to a file.

[DanH]

@d-healey Do you think it would be possible to create a mini preset browser for it like this https://forum.hise.audio/topic/3273/custom-mini-preset-browser-example-using-filesystem-api

[DanH]

@ustk Can't see how to 'save' a file from that link.. do you know how? Do I need to wrap it in a callback function from a button?

[Casey Kolb]

Did you load the snippet from that post into HISE? There's everything in there that you'd need to make what you're describing. You just need to export the table as base64 and save that string to a file. When you load the file, you restore the table from the base64 string like @ustk said.

[DanH]

@Lunacy-Audio I took a look at it the other day, thanks for posting it up :)

I'm a bit at a loss trying to work these base64 API's but will take another look at that snippet and see if any clues are inside!

[Casey Kolb]

The table's are definitely confusing! Took me a while to get a hang of them.

This is where you'll need to start:

// retrieve table processor from backend synth
var tableProcessor = Synth.getTableProcessor("Velocity Modulator1");

// export backend table as base 64 - this is what you save in the preset file
var tableData = tableProcessor.exportAsBase64(0);

// restore backend table from base 64
tableProcessor.restoreFromBase64(0, tableData);

[DanH]

@Lunacy-Audio Aaaaaahhh... ok that makes more sense! Brilliant, thanks mate :)

[Casey Kolb]

Also note: You never actually need to do anything with the visible table in the UI. It should just be linked to the backend table and you do all of the processing on the backend table.

[DanH]

@Lunacy-Audio How do you mean? The UI table is just a dummy? In this case my visible table in the UI is a global LFO. So I need to create a new table to replace this one, and link it to the Global LFO?
