PROGRAM mode: HD-1
6–9: Common KeyTrack
6–9a
6–9b
The two Oscillators share two Common keyboard tracking
generators, in addition to each Oscillator's dedicated
keyboard tracking for the Filter and Amp. You can use these
Common keytracks as AMS sources for modulating most
AMS destinations.
The Common Key Track parameters are shared by the entire
Program, but the actual AMS values are calculated
individually for each voice.
Overview
What does Keyboard Tracking do?
At its most basic, keyboard tracking lets you vary the
modulation amount as you play up and down the keyboard.
This can be useful for making the timbre consistent across
the entire range, or adjusting parameters according to pitch.
The NAUTILUS 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 modulation increase very quickly over the
middle of the keyboard, and then increase more slowly–
or not at all–in the higher octaves.
• Make the modulation 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.
