Been doing some pitch detection recently myself, but I went for an average magnitude difference function over an FFT. My understanding is that FFTs are a bit more intensive than autocorrelation-like solutions, but they work better with polytonal signals. Typing seems suited to single-tone instruments - did you consider using AMDF (or a similar function)?

To be honest all of this is on the border of my knowledge horizon. No I've never heard of AMDF but I will check it out for sure.

In the long run as I wrote I am aiming to support chords so that'll be necessery.

Would AMDF make the response time quicker?

For what purpose are you doing pitch detection?
