Suppose I want to create a radio button with which the user can control which filter an audio signal gets passed through. Something like this, conceptually (the red lines are connections I want to make, but are invalid)...

The problem is that I cannot pass the audio signal through the Hradio control because the variable typings are incorrect. I have tried some setups with Moses and Spigot, but I have not been able to figure out how to pass the audio signal through a conditional check in this way.

How can I set this patch up correctly?

@Metronome I would use [multiplex~] from zexy. then you can just route your radio into it. like so:

I also have a version [siglinterp~] in my library shadylib that fades linearly between the inlets using a signal, and there's also [clean_selector~] in lyonpotpourri that does the same thing but with a settable fade time

@Metronome
the vanilla way is to use [==] as condition and [*~] as amplifier.

In your use case the signals won't be uncorrelated, so don't use [pow~ 0.5]
(late edit: if timing must be exact: use [vline~])

I'm extremely partial to https://github.com/alexdrymonitis/filter_abstractions by Alexandros (based on MMB abstractions). Very nice sounding filters and you can switch the type by sending a symbol to the rightmost inlet.

subtracting a lowpassed signal from its' original results in a highpass (and vice versa):
