2) To edit the FM Operators: 1 Adjust the Envelope Parameters of Operator 1 (after turning off the other Operators). The Envelope Parameters control the level of the sound and how that level changes over time. See page 119 for more information. For now, try making some of these changes in the envelope: Adjust the OL (Output Level) parameter. Envelope Parameters Changing the OL parameter affects the volume of the selected Operator. Raise the OL parameter from 0 to 110 by using the pair of Data Control buttons just below the OL. (Pressing the A button raises the level, and pressing the B button lowers the level.) NOTE: The parameter value can be changed quickly when you press the Data Control button with the COARSE button held. Adjust the AR (Attack Rate) parameter. 8 Voice Edit Play the voice and notice how the changes you make affect the initial volume of the voice. By changing this parameter you can make the sound gradually get louder (lower settings) or have it reach its full volume all at once (higher settings). 109

1
Adjust the Envelope Parameters of Operator 1 (after turning off the
other Operators).

that level changes over time.
See page 119 for more information.
For now, try making some of these changes in the envelope:
Adjust the OL (Output Level) parameter.

Operator.
Raise the OL parameter from 0 to 110 by using the pair of Data

A
button raises
the level, and pressing the
B
button lowers the level.)
NOTE:
The parameter value can be changed
quickly when you press the Data Control

volume of the voice.
By changing this parameter you can make the
sound gradually get louder (lower settings) or have it reach its full
volume all at once (higher settings).
