It would be rather easy to do a JSFX using FFT to implement the pitch detect algorithm you describe, outputting Midi notes. But I suppose nobody will bother to do so, as close to never there will be a usable signal for such conversion.
OTOH, the "peak" files that Reaper creates for generating the spectrum display, will use a by far lower resolution than semitones. Otherwise they would be huge.
