Center-High and High-Top: negative ramps make the
keyboard tracking's output go down as you play higher on
the keyboard, and positive ramps make the output go up.
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 Low Break key. For normal key track, use
negative values.
Low-Center
This sets the slope between the Low Break and Center keys.
For normal key track, use negative values.
Center-High
This sets the slope between the Center and High Break keys.
For normal key track, use positive values.
High-Top
This sets the slope between the High Break key and the top
of the MIDI note range. For normal key track, use positive
values.

+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.
Note: If you set the Center-High ramp to +Inf or –Inf, the
High-Top parameter will be grayed out. Similarly, if you set
the Low-Center ramp to +Inf or –Inf, the Bottom-Low ramp
will be grayed out.
Amp Keytrack 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 Keytrack in the AMS list for the
desired parameter.
