Setup Mode
The Layer Function
7-9
Split Key
This parameter determines the boundary of the Split—it can be set to any number between
20 (G#0) and 108 (C8). By default, the Split Key is set to 60 (C4, or middle C). The chosen
key is the highest note in the Secondary Voice—one note above this note is the lowest note
in the Primary Voice. In addition to using the Value buttons, you can directly select the Split
Key by holding down the Sound Select H (aka Enter) button and then striking the desired
key on the keyboard.
Split Transposition
This parameter determines the transposition of the Secondary Voice relative to that of
the Primary Voice—it can be set to -24, -12, 0, 12, and 24. By default, Split Transposition
is set to 0. Note that if the Primary Voice is transposed, then the Secondary Voice will be
transposed by the same amount in addition to being transposed by the amount set for the
Split Transposition.
The Layer Function
Pressing the Layer Function button while in Setup mode will perform the Layer Function.
When you create a Layer in a Setup, you are in fact activating a Zone within the current
Setup. If the current Setup already has its maximum of four active Zones and you press the
Layer Function button, then a message will appear on the display indicating that you have
reached the maximum of four active Zones. The Layer Function is convenient, as you do
not need to go through Edit Setup Mode to delineate Zones, assign Programs, etc. You can
simply hit the Layer Function button, and the SPS4 automatically activates another Zone in
the Setup for you, with default values for parameters of the Layer.
The newly-activated Zone is the “Secondary Voice”. The currently active Zone(s) constitute
the “Primary Voice”.
There are three parameters (described below) that determine the behavior of the Layer. You
can view these parameters by scrolling through them using the Chan / Param buttons.
To edit them, use the Value buttons or the secondary alphanumeric entry functions of the
Object select buttons.
