The level of OP4 will now decrease as we play higher notes on the keyboard. This
will give a much more natural voice balance over the entire keyboard range.
STEP 7: SET THE LFO PARAMETERS
a. Press the LFO WAVE button and make sure that "triangle" is selected.
e1111 LW=triangl
b. Press the LFO SPEED button and set it to 30.
е1111 LFS=30
c. Press the LFO DELAY button and set it to 32.
е1111 LFD=32
d. Press the LFO PMD button and set it to 10.
е1111 PMD=10
Now if you play the keyboard, you should get a gentle vibrato effect (pitch mod-
ulation) which comes in gradually after a note is played. The gradual application
of the vibrato effect is produced by the setting of the LFO DELAY parameter. The
higher the setting, the longer the delay.
