3–2: Filter1 Mod.
This page contains the settings for Oscillator 1’s filter
modulation. Among other things, you can:
• Set up complex keyboard tracking shapes, and control
how the tracking affects filter cutoff.
• Control the effect of the Filter Envelope on filter cutoff.
• Assign AMS modulation for filter cutoff.
Filter B is available when the Filter Routing is set to Serial
or Parallel. Otherwise, the parameters for Filter B will be
grayed out.
3–2a: Keyboard Track
Most acoustic instruments get brighter as you play higher
pitches. At its most basic, keyboard tracking re-creates this
effect by increasing the cutoff frequency of a lowpass filter
as you play higher on the keyboard. Usually, some amount
of key tracking is necessary in order to make the timbre
consistent across the entire range.
The NAUTILUS keyboard tracking can also be much more
complex, since it allows you to create different rates of
change over up to four different parts of the keyboard. For
instance, you can:

3–2a
3–2b
