Is there such a thing as a note /midi controlled band pass filter ?
What i mean by that is if i input audio and pressed G2 on the keboard the filter would only allow through the frequencies associated with or around G2 ? Or inversely cut out the G2.
I googled note based VST and playable filter but cant find anything.
I've considered constructing a massive combinator with multiple band pass filters tuned to different frequencies but its seems like the kind of thing somebody clever might have already made in software.

You could try using "Neptune Pitch Adjuster" CV Pitch output and connect it to a filter's CV frequency input.
I did a quick test, feeding Neptune certain frequencies and controlling a filter with its CV pitch output - then verified the filtering with white noise from Thor through the filter.

Edit - like this: MIDI Note In -> Subtractor Sine Wave -> Neptune -> Pitch CV out -> Filter Frequency CV in
