Manual Vector Control
Manual vector control while playing can be accomplished by turning the vector
play mode on — press the VECTOR PLAY [ON/OFF] key so that either the
[LEVEL] or [DETUNE] indicator lights, and then select either level or detune
control by pressing the VECTOR PLAY [LEVEL/DETUNE] key.

The [VECTOR CONTROL] can then be used to control the selected
parameter — level or detune — along the vertical axis only if a 2-element voice
is selected, or along both the vertical and horizontal axes if a 4-element voice is
selected.

A (AWM)
D
B (FM)
When level vector control is selected, moving the control towards one ele-
ment (A, B, C or D) increases the level of that element while decreasing the
level of the others proportionally. The [VECTOR CONTROL] works in a similar
way when detune vector control is selected — moving the control towards one
element increases the pitch of that element while decreasing the pitch of the
others.
If the selected voice has a dynamic detune vector, the detune vector will
play while manual level vector control is selected, and vice versa.
The following diagrams should give you a rough idea of how the level or
pitch of each element in a 4-element voice is affected by [VECTOR CONTROL]
motion.
