This page contains the settings for Oscillator 1's filter
keyboard track. Among other things, you can:
• Set up complex keyboard tracking shapes, and control
how the tracking affects 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.
3–1–2a: 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 M3 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:
• Make the filter cutoff increase very quickly over the
middle of the keyboard, and then open more slowly–or
not at all–in the higher octaves.
• Make the cutoff 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 Key
Low, Center, and Key High–to be anywhere in between.
The four Ramp values control the rate of change between
each pair of keys. For instance, if the Lo Cent (Low-Center)
Ramp is set to 0, the value will stay the same between the
Key Low key and the Center key.
The Key value will be the break point, and the slope of the
lower and higher regions on the keyboard is specified by
Ramp.
At the Center key (the main hinge), the keyboard tracking
has no effect.
Intensity to A
This controls how much the keyboard tracking will affect
Filter A's cutoff frequency. The overall effect of the Keyboard
Track is a combination of this Intensity value and the overall
Keyboard Track shape.
With positive values (+), the effect will be in the direction
specified by keyboard tracking; if the ramp goes up, the
filter cutoff will increase.
