In Plug'n Script is it possible to make a multiband EQ?

I've done some exploring but noticed none of the EQ style presets use more that one band.
I suspect theoretically I should be able to stack some, but I thought I would just ask first before I waste my time trying.

Sure, there is no limitation in what you can do - you can chain as many filters as you want in your code. We will maybe do an EQ sample in the future.

How do you put two EQ's together in a code? I'm guessing each would need to call the KittyDSP::Biquad::Filter filter(audioInputsCount);

but how do you get past the error saying a function with the same name and parameters already exists?

Cascade your eq sections and give the functions different names. Start with a three band EQ with LoShelf, MidParametric, and HiShelf. You can use the cookbook examples to get started. If you carefully study the filter examples you can see how to plot a graph of the response as you change the parameters.

In fact, a useful exercise is to combine the (included) high pass example with the low pass example to come up with a bandpass. The filter functions are the easy part, plotting the graph is a bit more work.
