Detailed Description

Converts fundamental to a MIDI note value.

Things to know: C4 or "middle c" has a MIDI value of 60, then A4 (440Hz) has a MIDI value of 69 Taking that in account you can arrive to: $ fund_{midinote} = 69+log_{2^{(\frac{1}{12})}}(\frac{fundfrec}{440Hz}) $ and because $ log_{2^{\frac{1}{12}}}(a) = log_{e}(a)*17.31234 $ then: $ fund_{midinote} = 69+log_{e}(\frac{fundfrec}{440Hz})*17.31234 $.
