Polyphonic Transcription

I am using Windows 10 and working on audio to work with XLights. I have the piano track for a song and want to use it in Xlights. An article I found online referred to “Polyphonic Transcription” as a dropdown within either Effects or Analyze.

Simple question…where do I get the Plug-in?

I have attached the document I have been relying on.
Piano Effect in xLights.pdf (293 KB)

I assume they are referring to a VAMP plug-in from http://isophonics.net/QMVampPlugins though that page is not working for me.
