Description 
Freq 
The array of frequencies in Hz to convert to musical note pitch. 
aError 
Contains error in Hz (positive or negative) on output. This parameter can also be nil, if the error information is not required. To obtain error in % compute:
aError[i]/Freq[i]*100% 
aOctave 
Contains the octave numbers on output. 
aMusicalNotePitch 
Contains musical note pitch on the output. The values in MusicalNotePitch need to by typcasted to an enumerated type:
MusicalNotePitchToStr(TMusicalNotePitch(MusicalNotePitch[i])); 
MusicalScale
