4–2: Amp1 Mod.
4–2a
4–2b
This page contains the settings for Oscillator 1's Amp level
modulation. Among other things, you can:
• Set up complex keyboard tracking shapes to control the
Amp level.
• Assign AMS modulation for the Amp level.
• Control the effect of the LFOs on the Amp level.
The total effects of the modulation can increase the volume
to a maximum of two times louder than the Amp Level
setting.
4–2a: Keyboard Track
Keyboard tracking lets you vary the volume as you play up
and down the keyboard. Usually, some amount of key
tracking is necessary in order to make the volume consistent
across the entire range.
NAUTILUS's keyboard tracking can be fairly complex, if
desired. You can create different rates of change over up to
four different parts of the keyboard. For instance, you can:
• Make the volume increase very quickly over the middle
of the keyboard, and then increase more slowly–or not at
all–in the higher octaves.
• Make the volume increase as you play lower on the
keyboard.
• Create abrupt changes at certain keys, for split-like
effects.
How it works: Keys and Ramps
The keyboard tracking works by creating four ramps, or
slopes, between five keys on the keyboard. The bottom and
top keys are fixed at the bottom and top of the MIDI range,
respectively. You can set the other three keys–named Low
Break, Center, and High Break–to be anywhere in between.
The four Ramp values control the rate of change between
each pair of keys. For instance, if the Low-Center Ramp is
set to 0, the value will stay the same between the Low Break
key and the Center key.

You can think of the resulting shape as being like two
folding doors attached to a hinge in the center. At the Center
key (the main hinge), the keyboard tracking has no effect.
The two folding doors swing out from this center point to
create changes in the higher and lower ranges of the
keyboard.
Key
Low Break
This sets the breakpoint note between the two lower ramps -
the "hinge" of the lower door.
Center
This sets the center of the keyboard tracking - the main
"hinge." At this key, the keyboard tracking has no effect on
the volume, or on any AMS destinations.
High Break
This sets the breakpoint note between the two higher ramps -
the "hinge" of the upper door.
Entering notes from the keyboard
You can enter note numbers directly by playing them on the
keyboard. To do so:
1. Select one of the Key parameters.
2. Hold down the ENTER key.
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.
