Differences from other Keyboard Tracks
There are several differences between the Amp keyboard
tracking and the Filter and Common keyboard tracking.
For example, the results of the Ramp values are different. As
shown in the graphic "Amp Keyboard Tracking," below,
negative slopes are more steep than positive slopes.
Also, the amp does not have separate control of Intensity.
Instead, Intensity is always fixed at the maximum amount,
allowing keyboard tracking to change the volume from
complete silence to twice as loud as the programmed level.
Bottom-Low
This sets the slope between the bottom of the MIDI note
range and the Key Low key. For normal key track, use nega‐
tive values.
Low-Center
This sets the slope between the Key Low and Center keys.
For normal key track, use negative values.
Center-High
This sets the slope between the Center and Key High keys.
For normal key track, use positive values.
High-Top
This sets the slope between the Key High key and the top of
the MIDI note range. For normal key track, use positive val‐
ues.

+Inf and –Inf ramps
+Inf and –Inf are special settings which create abrupt
changes for split‐like effects. When a ramp is set to +Inf or
–Inf, the keyboard tracking will go to its extreme highest or
lowest value over the span of a single key.
When a ramp is set to +Inf, the keyboard tracking will go to
its highest value (double the programmed volume) over a
single half‐step.
Similarly, when a ramp is set to –Inf, the keyboard tracking
will go to its lowest value (complete silence) over a single
half‐step.
If you set the "Center‐High" ramp to +Inf or
–Inf, the "High‐Top" parameter will be grayed out. Simi‐
larly, if you set the "Low‐Center" ramp to +Inf or –Inf, the
"Bottom‐Low" ramp will be grayed out.
Amp KTrk is also an AMS source
You can use the keyboard tracking as an AMS source to
modulate other parameters, just like the envelopes and
LFOs. Simply select Amp KTrk in the AMS list for the
desired parameter.

Amp Amp1 Modulation
Amp Modulation
You can modulate the Amp level by both velocity and an
AMS source.
This modulation scales the basic Amp level and Amp EG
level parameters. The resulting volume is determined by
multiplying the volume changes of the amp EG by other
values such as AMS. If these original levels are low, the
maximum volume available with modulation will also be
reduced.
Velocity
Intensity
With positive (+) values, the volume will increase as you
play harder.
With negative (–) values, the volume will decrease as you
play harder.

Low velocity
AMS Source
This selects any AMS modulation source to control the
Amp1 level. For a list of AMS sources, please see "Alternate
Modulation Source (AMS)" on page 121.
AMS Intensity
This controls the depth and direction of the modulation.
For example, if "AMS Source" is set to JS+Y: CC#01, positive
(+) values of this parameter will make the volume increase
when move the joystick in the +Y direction.
Note that if the other modulation settings have already
raised the volume to its maximum level (double the Amp
Level and Amp EG level settings), the volume cannot be
increased any further.
LFO1
Intensity
This controls the depth and direction of LFO1's effect on the
oscillator's volume.
Negative (–) values will invert the LFO waveform.
AMS Source
This selects an AMS modulation source to scale the amount
of the LFO1 applied to the Amp level. For a list of AMS
sources, please see "Alternate Modulation Source (AMS)"
on page 121.
AMS Intensity
This controls the depth and direction of the LFO1 AMS
modulation for the Amp level.
LFO2
The parameters for LFO2 are identical to those for LFO1.
For more information, please see the descriptions under
LFO1, above.
