Route mid-high range piano input to a tapin object
I'm trying to route all the pitches on the piano above C5 (the octave above middle C) to a tapin object so I can run a delay on the incoming audio. I don't want to delay the low end of the piano sound though, just the high end. I tried isolating the high end with [1 minus lores~] and the onepole~ objects, but nothing seems to be working very well. Any thoughts?
You won't be able to fully isolate notes because lower notes will have overtones in the upper region, too.
That said, check out the help pages for filterdesign~ and cascade~. You can build a very steep high pass filter using those objects.
