Sub-Scale
Choosing a sub-scale for the Keyboard and/or Accompaniment
Sounds
You can assign a different scale (a sub-scale) to the Keyboard Sounds. This
will allow, for example, to play a piano solo with the Stretch tuning, while the
backing tracks continue to play in the Equal tuning. A different sub-scale can
be associated to each Keyboard Set.
You can also assign a sub-scale to all the Sounds of the Style, separate from
the Sounds of a MIDI Song (that will still use the main scale). So, you will be
able to play the Styles with a sub-scale, and the Songs with the main scale.
Choosing a sub-scale
1 Go to the Sub-Scale pane from the main page of the Style Play and Song
Play modes.
2 Use the Scale pop-up menu to choose the sub-scale. See above for a list of
the available scales.
▪ If needed, use the Key parameter (requested by some scales) to set the pre-
ferred key.
