Keyboard Track)
The two Oscillators share two Common keyboard tracking
generators, in addition to each Oscillator's dedicated key‐
board tracking for the Filter and Amp. You can use these
Common keytracks as AMS sources for modulating most
AMS destinations.
The Common Keyboard Track parameters are shared by the
entire Program, but the actual AMS values are calculated
individually for each voice.
What does Keyboard Tracking do?
At its most basic, keyboard tracking lets you vary the modu‐
lation 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 PS60 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.

Low Break
This specifies the note that will be the break point connect‐
ing the two sloped lines in the low region.
Center
This specifies the note that will be the break point in the cen‐
ter of keyboard tracking. At this key, the keyboard tracking
has no effect on the AMS destinations.
High Break
This specifies the note that will be the break point connect‐
ing the two sloped lines in the high region.
Ramp
Please see "Ramp" on page 38.
Bottom-Low
This sets the slope between the bottom of the MIDI note
range and the Low Break key. For normal key track, use
negative values.
Low-Center
This sets the slope between the Low Break and Center keys.
For normal key track, use negative values.
Center-High
This sets the slope between the Center and High Break keys.
For normal key track, use positive values.
High-Top
This sets the slope between the High Break key and the top
of the MIDI note range. For normal key track, use positive
values.
