4) FM Operators
The Operators 1 through 8 are the sine wave Operators of the algorithm.
When one of these Operators has been selected, the following parameters
are displayed:
2
1
3
5
4
6
1
OL (Output Level)
Determines the level of the selected Operator’s sound.
Range: 0 - 127
2
AR (Attack Rate)
Determines how quickly the Operator will reach its maximum
level after the key is played.
Lower values produce a slower
attack.
Range: 0 - 31
3
D1R (Decay 1 Rate)
Determines how much time it takes for the Operator to reach its
second level, set in the Decay 1 Level parameter.
Range: 0 - 31
4
D1L (Decay 1 Level)
Determines the second level setting of the Operator.
Range: 0 - 63
5
D2R (Decay 2 Rate)
Determines how much time it takes for the Operator to reach its
third level, or the minimum level before the key is released.
Range: 0 - 31
6
RR (Release Rate)
Determines how much time it takes for the level to reach 0 after
the key is released.
Range: 0 - 63
NOTE:
When the D2R is set to 0, the level set
by the D1L will be maintained until the
key is released.
The higher setting of the D2R rapidly
lower the level.
NOTE:
With the RR set too low, the sound
continues to sound.
