Recommendations for use with Chromatia Tuner 3.0 ("Options/Tuning"): ! ! Scale root key: ! Set this to the key of the hca. ! ! Octave stretch: ! 2 cent/octave is usually recommended. ! ! Master tuning: ! Usually, hca:s are tuned a little sharp, for example to A4 = 443 Hz ! (12 cent above 440 Hz). With "Chromatia", it is important to set ! the master tuning to the desired frequency of the scale root key. ! For a C hca, one should set C4 to 263 Hz (9 semitones of equal ! temperament below A4 = 443 Hz). ! ! References: ! ! The temperaments in this set of files (ji_hca*.scl) are based on ! recommendations by Pat Missin. See his text "Altered tunings". ! (www.patmissin.com) ! ! The Chromatia instrument tuner is made by FMJ-Software. ! (www.fmjsoft.com) ! ! The Scala scale file format used here is becoming a standard for ! exchange of scales and can be read by "Chromatia". !
