Key Detector for your live customers

Key Detector does not work in Waves Super Rack, but it should. Live is where we need it the most. Studio guys know what key they are working in (or at least they should) Live engineers aren’t writing or playing the music, so we don’t know what key it is in, and we can’t stop the show to ask. It would be super nice to have a plugin that could analyze the sound directly, not just read the notes in a DAW and tell us what key it is, then transmit that to our other waves plugins just like your daw only version. Thanks!
