Setting the Root Key
With this function, the root key can be set for each temperament.
When the [MANUAL] button is pressed so that its lamp lights,
the root key can be specified by pressing one of the Note Select
buttons manually.
When the [AUTO] button is pressed so that its lamp lights, the
root key and chord type (major or minor) will be determined by
playing several notes on the keyboard.
If the notes played cannot be recognized as a
Note
chord, the current root key and current chord
type will be maintained.
