R2, L2
When a note is played and the Operator has reached the L1 level, the Operator level begins
to change to the level set by the L2 parameter. The R2 parameter determines the rate at
which the Operator output level changes from the L1 level to the level set by L2.
The R2 parameter can be set to rate values from 0-99. Smaller rates make changes happen
slowly, while larger rates make changes happen quickly.
The L2 parameter can be set to values from 0-99, where 0 is equivalent to silence or no
modulation, and 99 is equivalent to the maximum possible Operator volume or modulation
depth.
R3, L3
When a note is played and the Operator has reached the L2 level, the Operator level begins
to change to the level set by the L3 parameter. The R3 parameter determines the rate at
which the Operator output level changes from the L2 level to the level set by L3.
The Operator remains at the level set by the L3 parameter for as long as a note is held.
The R3 parameter can be set to rate values from 0-99. Smaller rates make changes happen
slowly, while larger rates make changes happen quickly.
The L3 parameter can be set to values from 0-99, where 0 is equivalent to silence or no
modulation, and 99 is equivalent to the maximum possible Operator volume or modulation
depth.
R4, L4
When a note is played and released, the Operator level begins to change to the level set by
the L4 parameter. The R4 parameter determines the rate at which the Operator output level
changes from its current level to the level set by L4.
The R4 parameter can be set to rate values from 0-99. Smaller rates make changes happen
slowly, while larger rates make changes happen quickly.
The L4 parameter can be set to values from 0-99, where 0 is equivalent to silence or no
modulation, and 99 is equivalent to the maximum possible Operator volume or modulation
depth.
Note: When the L4 parameter is set to values 1-99, Operator level will always eventually
change to a level of 0 (silence or no modulation), as if L4 was set to 0. Larger L4 values make
changes happen slowly, while smaller L4 values make changes happen more quickly. This
prevents infinitely sustaining notes which can occur in classic FM synthesizers.
