MODIFIERS
Th
ese Parameters allow you to modify various characteristics of
the Oscillators.
NOTE: See page 53 “Oscillator Types And Characteristics” for
details.
OCTAVE
Setting Range:
-2 ~ ±0 ~ +2
Th
is allows you to select the Octave or pitch at which the selected
Oscillator will sound.
At “0” the selected Oscillator will sound at unison or actual
pitch. “-2” will sound two octaves lower and “+2” will sound
two octaves higher.
NOTE: This Parameter is linked to the [OCTAVE] buttons on the

KEY
TRACK
Setting Range:
±0 ~ +100 [cents]
Th
is allows you to adjust the amount of pitch change between
keys on the keyboard.
At “+100” the musical distance between any two adjacent notes
will be 100 cents or one half-step. Th
is is the normal setting.
At “+50,” the notes will be one quarter-step apart. At “0” every
note on the keyboard will sound the same pitch.
EG
DEPTH
Setting Range:
-64 ~ ±0 ~ +63
Th
is allows you to adjust the depth of the pitch change by the
Pitch Envelope.
At “0” there is no pitch change. At “-64.” the pitch will change
down one octave. At “+63,” the pitch will change up one
