3–2: Filter1 Modulation
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.
