VOICE EDIT MODE
Velocity Sw (velocity switch): When this is "on",
strongly played notes will cause the pitch EG to
change over a greater range.
AFM ELEMENT DATA
7. (F2) AFM pitch EG (EG settings)
Summary: The pitch EG creates a fixed shape of
pitch change over time for each note. To switch
the pitch EG on/off for each operator, see 7. (F1)
AFM pitch EG (Switch).
Procedure:
From: AFM Element job directory (JUMP #230)
Select: job 07:PitchEG and press (JUMP #247)
F2 (EG)
Specify: pitch EG parameters
This indicates the EG segment ("seg1-3" or
"rel1") from which the pitch EG graphic display
begins. If the EG is too long to be fully shown in
the LCD, hold SHIFT and press F7 or F8 to move
the pitch EG graphic display to a different
segment.
This indicates the time length shown by the
graphic display. To change this, hold SHIFT and
press F1-F6 (x1, x2, x5, x10, x20, x50). The
exact length of time will depend on the range.
When the pitch EG range is 1 octave, the
graphic display will cover approximately 0.5
seconds at "x1" and approximately 5 seconds at
"x50".
The pitch EG is graphically displayed.
R1-R3, RR1 (0...63): Keyon Rates 1-3 and the
Release Rate determine the speed of the pitch
EG. Higher settings result in faster change. A
rate of 63 will make the pitch jump instantly to
the next level.
L0-L3, RL (-64...+63): Keyon Levels 0-3 and
the Release Level determine the levels of the
pitch EG. Positive settings raise the pitch and
negative settings lower the pitch.
Rates and Levels: When you press a key, the
pitch will begin at the level of L0, and will
change at the rate of R1 to level L1. When the
level reaches L1, the pitch will change at the
rate of R2 to the level of L2. When the pitch
reaches L2, it will change at the rate of R3 to the
level of L3 and will stay at L3 as long as the key
is pressed.
When the key is released, the pitch will
change at the rate of RR to the level of RL.
Note: Even if the AFM pitch EG and the AWM pitch
EG have identical Rate settings, there will be
slight differences in the timing of the pitch
chance.
