Filter1 Modulation
Here you can edit the filter keyboard tracking and filter
modulation for oscillator 1. These settings include the fol‐
lowing.

• 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.
• 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.

Keyboard Track
Most acoustic instruments get brighter as you play higher
pitches. At its most basic, keyboard tracking re‐creates this
effect by raising the lowpass filter cutoff frequency 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 PS60 keyboard tracking can also be much more com‐
plex, since it allows you to create different rates of change
over up to four different parts of the keyboard.

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 the
Ramp.
At the Center key (the main hinge), the keyboard tracking
has no effect.

Intensity
Intensity to A
[–99...+99]
This controls how much the keyboard tracking will affect
Filter A’s cutoff frequency. The overall effect of the Key‐
board Track is a performance 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 fil‐
ter cutoff will increase.
With negative values (–), the effect will be in the opposite
direction; if the ramp goes up, the filter cutoff will decrease.

Ramp
Positive ramp values mean that the keyboard tracking out‐
put increases as you play farther from the Center Key; nega‐
tive 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.
