Japanese scales

Please add these Japanese scales as they are very useful. For many years now, they have been available in other MIDI utilities that deal with melody and harmony.

A variety of musical scales are used in traditional Japanese music. While a twelve-tone (dodecatonic) Chinese scale has influenced Japanese music since the Heian period, in practice Japanese traditional music is often based on pentatonic (five tone) or heptatonic (seven tone) scales.[1] In some instances, harmonic minor is used, while the melodic minor is virtually unused.
