Parametric EQ - Limit the amount of nodes?

[DanH]

Can we limit the number of bands the user can implement in the Parametric EQ?

Or maybe prevent the user from being able to add any nodes in the EQ floating window, but be able to control existing nodes with the usual mouse functions...

@DanH EQComponent.cpp

comment out lines 630-636 to prevent adding new nodes

Potentially useful if you wish to create a (for example) 5 band EQ that has all the functionality of the Parametric EQ but removes the possibility of the user adding more nodes and therefore creating scripting issues if you wish to script controls for the 5 bands etc.

You also need to remove the right-click menu (or item within) to disable 'Delete All Bands' as well as 'Delete Band'. To do this I've commented out lines:

• 531
• 553 - 558
• 608 - 615

@DanH or add a property to the Parametric EQ

.set("numNodes", 5);

[DanH]

@ulrik I tried

ParametricEQ1.set("numNodes", 5);

but get the error 'function not found'...

EDIT: oh wait do you mean add this into the source code?

[ulrik]

@DanH I mean that Christopher could add a property to the EQ

[DanH]

@ulrik That would be nice @Christoph-Hart :)

It might not be that hard to add that property yourself if you want to explore C++.

[ulrik]

@d-healey I just bought a c++ course on Udemy, it will be my summer reading :)

Is This Available Now?

[DanH]

Which bit?

@Natan you mean a function to limit the amount of nodes? I don't think so

[lalalandsynth]

@DanH Is this by any chance possible now ?

[DanH]

@lalalandsynth I don’t think so. I reckon there must be a way to edit the mouse callback for adding nodes in the source code. My initial idea was to create the nodes you require and then edit the source to prevent users adding their own.

Failing that what you want to do might be possible using multiple EQ filters in scriptnode

Digging up quite an old one!

Is there a way to limit the number of nodes nowadays?
Only found interrogations...

[DanH]

@ustk I seem to remember being able to edit the data field but can't find an example. I did it in the source code. Do you want a fixed amount always visible or allow the user to add a max of x?

[ustk]

@DanH always visible and not able to edit the type. I’d prefer not to edit the source unless it’s customisable for a pull request compatibility.

But seeing my needs I might just end up with a panel based custom solution lol

[DanH]

@ustk you're good at those

@ustk
I solved it using an EQ broadcaster. The value you get from the broadcaster is the index of the band.

If the index is below my maximum value, e.g. 8, nothing happens except that I save the current status of the EQ in a variable (Effect.exportState()).

If the index exceeds my maximum value, I show the user a message and reset the status of the EQ to the status I saved in the variable. It's actually pretty simple. :-)

At least that works with HISE's internal EQ.

@Oli-Ullmann Mmm clever!
