A demonstration of a flanging effect applied to the Music extension instruments. (@NerdBoy628 added the keyboard requested in @papipupepappa’s original project, and I modified some code to be able to generate the flanging effect without using clones - The keyboard still uses clones for the keys.) Choose the instrument, adjust flange settings, and then play the keyboard. To disable the effect, set "# of duplicates" to 0. I also made a custom block in the keyboard sprite to run its clone creation script without screen refresh, so now the whole keyboard instantly appears when the green flag is clicked.
