Time Modulation
These parameters let you use an alternate modulation source to
modify the amp EG times that were specified in “Time” on
page71.
AMS1 (Alternate Modulation Source 1 - Time)
This parameter specifies the source that will control the “Time”
parameters of the amp EG (see “AMS (Alternate Modulation
Source) list” on page77). With a setting 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 “Keyboard Track-
ing” on page70) will control the EG “Time” parameters. With
positive (+) values of this parameter, positive (+) values of
“Ramp (Ramp Setting) will cause EG ti mes 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
“At (Attack Time Swing)”, “Dc (Decay Time Swing)”, “Sl (Slope
Time Swing)”, and “Rl (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
“Level” parameters (see page71).
At (Attack Time Swing)
This parameter specifies the direction of the effect that “AMS1”
will have on “Attack”. With positive (+) values of “Intensity”, set-
ting 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.
Dc (Decay Time Swing)
This parameter specifies the direction of the effect that “AMS1”
will have on “Decay”. With positive (+) values of “Intensity”, set-
ting 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.
Sl (Slope Time Swing)
This parameter specifies the direction of the effect that “AMS1”
will have on “Slope”. With positive (+) values of “Intensity”, set-
ting 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.
Rl (Release Time)
This parameter specifies the direction of the effect that “AMS1”
will have on “Release”. 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.
LFO: 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.
Waveform
This parameter selects the LFO waveform. The numbers that
appear at the right of some of the LFO waveforms indicate the
phase at which the waveform will begin.
Amp 1 EG changes (Time) (AMS=Velocity, Intensity= a positive (+) value)
Amp 1 EG changes (Time)
(AMS=Amp KTrk +/+, Intensity = a positive (+) value)
(When Amp Keyboard Track “Low Ramp”= a positive (+) value, and
“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.
