GUI for the Parametric EQ

Dan Korneff

@dustbro said in Stereo Effect Project. Example?:

@duno I was wondering the same thing, so I decided to do a little test.
By using the Console.print() command, I was able to see that ParametriqEQ.BandOffset is an Integer that is equal to 5. By doing the same with ParametriqEQ.Gain, I saw that was equal to 0.
These are Index numbers that dictate which control you are scripting.
Looking at the Module browser, I can see that each EQ has 6 Index points for each EQ node:

The first 5 appear to be controls, and the BandOffset is just an index used to multiply.
At EQ Node 0, the index is:
0 - Gain
1 - Freq
2 - Q
3 - Enabled
4 - Type
So what happens when you have another EQ node in the effect? The index list starts over at 5.
5 - Gain
6- Freq
7 - Q
8 - Enabled
9 - Type
And then the next node would start at 10.
So what does it all mean?? lets do some math.
{
    local index = 1 * ParametriqEQ.BandOffset + ParametriqEQ.Gain;
	ParametriqEQ.setAttribute(index, value);
};
In the script above we're creating a local variable called index. This is used to gather an integer that is directly related to a specific index on the EQ.
If we convert them to numbers, the equation looks like this:
1 * BandOffset + Gain
or
1 * 5 + 0 = 5
5 is now passed to the line of code below:
ParametriqEQ.setAttribute(index, value);
Which is the same as if we typed:
ParametriqEQ.setAttribute(5, value);
Looking at the chart above, we can see that Index 5 is the Gain of 2nd EQ node.

@dustbro nice one man! That should help me lots!

Christoph Hart

The formula is pretty simple: You take the band index that you want (starting with zero!), multiply it with ParametriqEQ.BandOffset and then just add the parameter enum you want to control.

So:

Frequency of the 14th band: 13 * Eq.BandOffset + Eq.Frequency

Q of the 12049th band: 12048 * Eq.BandOffset + Eq.Q...

@Christoph-Hart Thanks Christoph

Ok I built a 4 band eq into my project. It doesnt work after saving and reopening. I decided to isolate the issue. It crashes my hise on import. Does it crash yours?

Tod Slaughter

@Natanr thanks :) Nice to know it's not just me

Dan Korneff

@Tod-Slaughter I'll check today

ustk

I found some issues in your snippet, like the name of the MasterEq that is, in fact, MasterEq1
Some callbacks have a wrong name (same name used twice or more)
Bad band offset...

But despite these corrections, it still crashes...

ustk

Ok so the cause of the crash was the name of the main container which was the same as the EQ

I simplified your code, you don't need the local index since you can directly put the band offset calculation in the setAttribute.
Also, an if(value) statement is mandatory if you want your EQ to reflect the buttons at compile time (otherwise the last callback will always be taken into account, no matter the state of the buttons)

I didn't think the name would have made a difference but that does open here. Many many thanks!

@Tod-Slaughter Hise stopped crashing the very moment I changed the master container's name...
Glad it works

ustk

@Tod-Slaughter I just noticed there's still a mistake in the Low and LowMid Q

Tod Slaughter

@ustk It's not working in my project. I'm just checking if you changed the knob ranges too

Tod Slaughter

No the knob ranges are the same

Tod Slaughter

@ustk Just spotted that too

ustk

@Tod-Slaughter if it's not working, have a look at the IDs (eq, master container...) in your project too, and be sure they correspond to the script definitions

Tod Slaughter

Fixed the q

ustk

@Tod-Slaughter again it was an error in the callback definition:
