Decomposing FFT bands

Hello,
I’m working to implement an automat that extract information from notes played on a piano using the frenquencies bands to identify what note or sector of the piano its being played. I though to work with a FFT, however I’m wondering if there is any way I can read the amplitud and frequncies sperated from bands. FFT gives me an arrange of #, but I need to separate them in order to analyze them one by one and hopefully in real time. Not sure if this would be too demandin on resources either.
Thanks in advance for any comments friends.

Hey Pablo,

Unless I misunderstand you, the fiddle~ object does exactly what you
want without having to muck around with FFTs.

is the fiddle object available for windows users? I tried to find it online, but I could find only the Mac version of it.
