EQ curve from object.

[d.healey]

Is it possible to load a curve into the eq from an object? And if so is it reasonable to swap the curve with every note on, or will I get glitcheyness?

[Matt_SF]

@d-healey not quite what you're asking but, I've tested once changing randomly the eq curve (multiple points) on note ons and didn't get any glitches...

@d-healey
You can create Base64 state of the current EQ curve, so you can write it to an object, then re-load it with restoreState API. I haven't tried to load it on each note yet.

[d.healey]

@orange I thought about that but what I'd like to do is perform an analysis outside of HISE and import the curve from a file.

@d-healey said in EQ curve from object.:

@orange I thought about that but what I'd like to do is perform an analysis outside of HISE and import the curve from a file.

So make a plugin or standalone app with the draggable filter that is connected to the Parametric Eq for analyzing purposes. Put a button on the GUI that exports the state of the eq using exportState so you'll be saving the eq curves to files. Analyze outside of Hise and create curve files. Then import these files to your real project with restoreState.

Since each eq plugin's filter coefficients are different, your curve analysis and final curve settings should be done with the same eq. Otherwise, the resulting sound won't match the analysis.

restoreFromState is definitely not something you want to call in an onNoteOn callback.

[d.healey]

@orange It's not possible to perform the analysis I'm doing using HISE. I'm trying to recreate Kontakt's AET filter.

@Christoph-Hart Is there a way to add nodes to the eq programmatically?

[Christoph Hart]

@d-healey Why don't you use scriptnode for it?

[d.healey]

@Christoph-Hart Because I'm a noob :) can I load in curves from external analysis into a scriptnode filter?

[Christoph Hart]

@d-healey Sure, it's called scriptnode for a reason. You can grab references to every node and set the parameter programatically.

[d.healey]

@Christoph-Hart I have some learning to do :)

[Dan Korneff]

@d-healey Can't wait for the Patreon video

[Christoph Hart]

@Dan-Korneff Everybody is waiting for this video and I really don't know why it takes so long for this guy to learn scriptnode :)

[d.healey]

I can't see a node that is like the EQ, are you suggesting I add individual filters for every band? Is this more/less efficient than the using the stock EQ?

[Dan Korneff]

@d-healey I believe it's only 1 band per node.

[d.healey]

@Dan-Korneff And if I wanted to add 30 or so bands, any idea how the efficiency would compare to the EQ effect? And how would it compare to just adding 30 filter effects?

[Matt_SF]

@d-healey I can be wrong but : Talking only about using 30 1-band EQ nodes, I would guess that once your ScriptFX is compiled into a HardcodedFX, there won't be much of a difference than using an EQ module with 30 bands.

[Christoph Hart]

Yes it‘s pretty much the same.

[d.healey]

Excellent. Is the clone control node thing working properly?

[Christoph Hart]

@d-healey A simple test for your use case works, but the entire concept is a little unstable (it's basically the child panels of scriptnode) so I'm not sure I would recommend it at this point.
