6–5: OSC 2 AMS Mix
This page controls the two AMS Mixers for Oscillator
2. These are available only when the Oscillator Mode
is set to Double; if not, the page will be grayed out.
6–9: Common Keyboard Track
6–9a
6–9b
The two Oscillators share two Common keyboard
tracking generators, in addition to each Oscillator's
dedicated keyboard tracking for the Filter and Amp.
You can use these Common keytracks as AMS sources
for modulating most AMS destinations.
The Common Key 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
modulation 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 OASYS 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.

The parameters are identical to those for Oscillator 1,
as described under "6–1: OSC 1 AMS Mixer," on

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 Low Break, Center, and High
Break–to be anywhere in between.
The four Ramp values control the rate of change
between each pair of keys. For instance, if the Low-
Center Ramp is set to 0, the value will stay the same
between the Low Break key and the Center key.
