Setting the Base Note for Each Scale
When the base note is changed, the pitch of the keyboard is transposed, yet the orig-
inal pitch relationship between the notes is maintained. Please make sure to specify
the appropriate Base Note, if you select a scale other than Equal Temperament, or
create an original scale via Scale Tune function.
Press the [FUNCTION] button then use the CATEGORY [<] and [>]
buttons as many times as necessary to select the "Base Note." Use
the dial to select the Base Note from C, C#, D, Eb, E, F, F#, G, Ab, A,
Bb, B.
The setting can be reset to the initial default value by pressing the [-/NO] and [+/
YES] buttons simultaneously.
Tuning Each Note to Create an Original Scale
You can tune the individual notes in cents to create your original scale. The term
"cent" refers to one hundredth of a semitone (i.e., 100 cents = 1 semitone). After
selecting the appropriate Base Note, follow the instructions below.
