Yamaha V50 - Page 50

These envelope generator settings are made separately
for each operator 1—4. The number of the operator
currently being set is shown in the lower left of the
display. Repeatedly press |_© | to step through operators
1+2343-4, and make settings for each.
As shown in the diagram, an envelope generator
uses four “rates” and one “level” to modify the output
of each operator over time. (A similar diagram is printed
on the right side of the V50 front panel.)
It is possible to copy the settings of an envelope
generator to another operator (see page 120).
Output level
pol
SITET DI
Minimum levet | : : Time
Key is pressed Key is released
Attack rate (AR) neis The speed of the change from minimum
to maximum level, starting when a key
is pressed.
Decay 1 Rate (D1R).......... The speed of the change from maximum
to D1L level, starting when maximum
level is reached.
Decay 2 Rate (D2R) .......... The speed of the decay from D1L level.
Release Rate (RR). The speed of the decay starting when
the key is released.
Decay 1 Level (D1L).......... The level after decaying from the max-
imum level.
These settings result in a change as follows.
(1) When a key is pressed, the output level rises at the
rate of AR to the maximum level.
(2) When the maximum level is reached, the output level
decreases at the rate of DIR to the level DIL.
(3) While the key remains depressed, the level will
continue to decrease at the rate of D2R.
(4) When the key is released, the level will decrease at
the rate of RR.
(1) AR
@ Function
Set the rate at which the output level rises to maxi-
mum.
E Settings
0-31
E Explanation
A setting of 0 is infinitely slow, and a setting of 31
is the fastest attack.
46 Voice Edit
(2) DIR
Æ Function
Set the rate at which the level decreases to DIL.
E Settings
0-31
Æ Explanation
Higher settings create a greater feeling of attack, and
lower settings create a slower decay.
Note:
If the DIL is close to the maximum of 15, this DIR
setting will have little effect.
(3) DIL
@ Function
Set the level to which the output will decay after @
reaching maximum.
E Settings
0-15
Æ Explanation
When D2R is 0, this DIL level will be the level of
the sustained sound.
(4) D2R
Æ Function
Set the rate at which the level decreases after reaching
DIL.
@ Settings
0-31
@ Explanation
When this D2R is 0, the output will stay at the DIL ®
level as long as the key is depressed. ;
(5) RR
Æ Function
The rate of the decay after the key is released.
E Settings
LIS
Æ Explanation
Larger settings result in a faster (shorter) decay.
(6) Shift (EG shift)
A Function
Select the width of change produced by the envelope
generator.
