Find the right formula?

[ulrik]

I'm experimenting with the Parameter EQ and using a panel to drag the nodes
The gain setting for each node is working fine but to set the frequency is more difficult.

I have the knob property set to "frequency" but I need to use math to calculate the curve cause the the drag position doesn't match the frequency, is it possible to do, and how would I approach it, any guides?

Any help will be appreciated!

@ulrik Why don't you user the draggable filter floating tile?

@ulrik this has been covered - trying to find the post / snippet!

@d-healey I would love to but is it possible, with the draggable filter, for the user to set all the parameters?
and also to be able to set it via knobs or typing?

[ulrik]

@DanH Great, thank you Dan!

[DanH]

@ulrik hope it helps - I've been trying to come up with ways to customise the Draggable EQ but its difficult!

[ulrik]

@DanH Yeah, I've spend some time on it as well, then I decided to try this way instead :)

@ulrik we need to persuade @ustk to release the code he used for his one :face_with_tears_of_joy:

[d.healey]

@ulrik Yes of course, just use knobs as you do already, also right clicking on the tile brings up additional options.

[ulrik]

@DanH Absolutely

@d-healey This is what I get when using the draggable filter

How do I set the q-factor?

And how do I do with knobs if the User set 8 tiles or 3?

[d.healey]

You'd need to limit the number of bands or provide an option to select which band to edit. I'd go for limiting the number of bands - no, I don't know how, probably c++.

[ulrik]

@d-healey Yes I thought of that, limiting the bands so it would not be possible to set another band, but how you would do that I don't know.

the end user sets the q using the scroll wheel...if you use the draggable eq panel - you wont need ANY knobs, it configs itself...

[ulrik]

@Lindon Great, scrolling, thank you!
What if you want to have knobs and also have the choice to type the values in, would it be possible?

[d.healey]

@ulrik Yes, like I said just add knobs as you usually would, but if the user adds more bands than you have knobs you'll need to provide a way for the user to select which band(s) they want to edit. If it was me I'd try to find a way to limit the number of bands to the number of knobs.

[DanH]

@d-healey I was previously digging around in EqComponent.cpp

[ulrik]

@d-healey Yes that's the way to go, limiting the number of bands, I will think about it and see if I find a suitable solution...thank you
