4–5: Pitch EG/Mod
This page lets you modulate the pitches of Oscillators 1
and 2 separately–as opposed to the Pitch Common
page, whose controls affect both Oscillators at once.
All pitch modulation for Oscillator 1 also affects the
Sub Oscillator.
4–5a: OSC 1 & Sub OSC Pitch EG
EG Select [Filter EG 1, Pitch EG 2,
EG 3, EG 4, Amp EG
This selects an EG to modulate the pitch of Oscillator 1
and the Sub Oscillator.
There are four assignable EGs, in addition to the Amp
EG. Each of these can be used as a modulation source
to control a wide variety of parameters.
In the midst of all this flexibility, we thought it would
also be good to provide a little structure. With this in
mind, EG 1 is named EG 1 (Filter) and EG 2 is labeled
EG 2 (Pitch).
Please take these names as suggestions, rather than
restrictions. If you like, you’re free to use these EGs to
control any EG or AMS destination, or to use other EGs
to control Filter Frequency and Pitch.
Intensity [-48.00…+48.00]
This controls the initial effect of the Pitch EG on the
frequency of Oscillators 1 and the Sub Oscillator, in
half-steps, before any AMS modulation.
The Pitch EG’s shape can swing all the way from +99 to
-99. When the Intensity is set to a positive (+) value,
positive values from the EG raise the pitch, and
negative values lower the pitch.
When the Intensity is set to a negative (-) value, the
effect of the EG is reversed; positive EG values mean
lower pitches, and negative EG values mean higher
pitches.
AMS [List of AMS Sources]
This selects an AMS modulation source to scale the
amount of the Pitch EG applied to Oscillator 1 and the
Sub Oscillator.
For a list of AMS sources, see “AMS (Alternate
Modulation Source) List” on page 967.
Intensity [-48.00…+48.00]
This controls the depth and direction of the pitch EG
AMS modulation. The AMS modulation and the initial
Intensity are added together to determine the Pitch
EG’s final effect.
4–5b: OSC 2 Pitch EG
Oscillator 2 has the same Pitch EG parameters as
described under “4–5a: OSC 1 & Sub OSC Pitch EG,”
above.
4–5c: OSC 1 & Sub OSC Pitch Modulation
AMS 1 [List of AMS Sources]
This selects the first modulation source for controlling
the pitch of Oscillator 1 and the Sub Oscillator. For a
list of AMS sources, see “AMS (Alternate Modulation
Source) List” on page 967.
Intensity [+/-48.00 semitones]
This controls the depth and direction of the AMS 1
pitch modulation, in semitones.
