Algorithm
At the left side of the display is the Algorithm used for this voice.
An algorithm is a kind of ﾒmapﾓ that shows how the sound
components of the voice are related to each other. Each voice
has nine separate sound components and they are called
ﾒOperators,ﾓ AWM Operator and FM Operators 1 through 8.
3
Begin changing the sound by turning off all Operators, except Operator 1.
To turn off each Operator:
1. First, use the pair of Data Control buttons just below the algorithm
display (below the box 1; the second from the left) to select an
Operator.
The currently selected Operator number is surrounded by the
ﾒBrackets.ﾓ
Pressing the A button move the ﾒBracketsﾓ counter clockwise,
and pressing the B button move the ﾒBracketsﾓ clockwise. Move
the ﾒBracketsﾓ to the Operator 2.
2. Then press one of the far left pair of Data Control buttons to turn
the selected Operator off.
Reverse display (dark box)
indicates that the Operator is
on; normal display indicates
the Operator is off.
These buttons turn the
selected Operator on and off.
3. Repeat the above process for all of the Operators except Operator 1.
As you turn off each Operator, play the voice and listen to how
the sound changes.

depending on the voices.
NOTE:

not shown in the same display, you can
show them by moving the ﾒBracketsﾓ to
the AWM operator or past the FM
