3. While holding ENTER, play a note on the
keyboard.
Ramp
Positive ramp values mean that the keyboard tracking
output increases as you play farther from the Center
Key; negative ramp values mean that it decreases.
Because of this, the meanings of positive and negative
ramp settings will change depending on whether the
ramp is to the left or right of the Center Key.
Bottom-Low and Low-Center: negative ramps make
the keyboard tracking's output go down as you play
lower on the keyboard, and positive ramps make the
output go higher.
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

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.
