Amp EG ‘Time’ modulation
These parameters let you use an alternate modulation
source to modify the amp EG times that were specified
in “Attack/Decay/Slope/Release Time” on page 120.
AMS1(T) (Alternate Modulation Source 1 - Time)
This parameter specifies the source that will control the
“Time” parameters of the amp EG (see “AMS (Alter-
nate Modulation Source) list” on page 124). With a set-
ting of Off, there will be no modulation.
Intensity
This parameter specifies the depth and direction of the
effect that “AMS1” will have. For example, if
“AMS1(T)” is Amp KTrk +/+, the (Amp) Keyboard
Track settings (see “Amplifier keyboard tracking” on
page 118) will control the EG “Time” parameters. With
positive (+) values of this parameter, positive (+) values
of “Ramp (Ramp Setting) will cause EG times to be
lengthened, and negative (–) values of “Ramp (Ramp
Setting)” will cause EG times to be shortened. The
direction of the change is specified by “Attack Time
Swing”, “Decay Time Swing”, “Slope Time Swing”,
and “Release Time”.
When “AMS1(T)” is Velocity, positive (+) values will
cause EG times to lengthen as you play more strongly,
and negative (–) values will cause EG times to shorten
as you play more strongly. With a setting of 0, the EG
times will be as specified by the “Amp envelope”
parameters (see page 120).
Attack Time Swing
This parameter specifies the direction of the effect that
“AMS1” will have on “Attack Time”. With positive (+)
values of “Intensity”, setting this parameter to + will
allow AMS1 to lengthen the time, and setting it to –
will allow AMS1 to shorten the time. With a setting of 0
there will be no effect.
Decay Time Swing
This parameter specifies the direction of the effect that
“AMS1” will have on “Decay Time”. With positive (+)
values of “Intensity”, setting this parameter to + will
allow AMS1 to lengthen the time, and setting it to –
will allow AMS1 to shorten the time. With a setting of 0
there will be no effect.
Slope Time Swing
This parameter specifies the direction of the effect that
“AMS1” will have on “Slope Time”. With positive (+)
values of “Intensity”, setting this parameter to + will
allow AMS1 to lengthen the time, and setting it to –
will allow AMS1 to shorten the time. With a setting of 0
there will be no effect.
Release Time
This parameter specifies the direction of the effect that
“AMS1” will have on “Release Time”. With positive (+)
values of “Intensity”, setting this parameter to + will
allow AMS1 to lengthen the time, and setting it to –
will allow AMS1 to shorten the time. With a setting of 0
there will be no effect.
AMS2 (Alternate Modulation Source 2)
This is another alternate modulation source for the
Amp EG. See above “AMS1” parameters.
PAGE 17 - LFO1
In this and the next page you can make settings for the
LFO that can be used to cyclically modulate the Pitch,
Filter, and Amp of each oscillator. There are two LFO
units for each oscillator. By setting the LFO1 or LFO2
Intensity to a negative (–) value for Pitch, Filter, or
Amp, you can invert the LFO waveform.
Wave
This parameter selects the LFO waveform. The num-
bers that appear at the right of some of the LFO wave-
forms indicate the phase at which the waveform will
begin.
Frequency
Set the LFO frequency. A setting of 99 is the fastest.
00…99 Frequency rate.

“High Ramp” = a positive (+) value)

Random1 (S/H):
Conventional sample & hold (S/H) in which the
level changes randomly at fixed intervals of
time
Random2 (S/H):
Both the levels and the time intervals will
change randomly.
Random3 (S/H):
The maximum level and minimum level will
alternate at random intervals of time (i.e., a
square wave with random period).
Random4 (Vector)
Random5 (Vector)
Random6 (Vector)
These types cause Random 1–3 to change
smoothly. They can be used to simulate the
instability of acoustic instruments etc.
