The Pitch EG, or Envelope Generator, lets you create
complex, time-varying changes to the pitch of Oscillators 1
and 2. The parameters on this page control the shape of the
EG. For instance, you can:
• Create the basic EG shape by setting the levels and times
of each segment.
• Control the curvature of each EG segment, for subtle
control over the sound of the EG.
• Set up complex modulation of EG levels and times.
• Set up an AMS source, such as an LFO, to restart the
EG.
To control how much effect the EG has on the pitch, use the
Pitch EG parameters on the OSC/Pitch– OSC1(2) Pitch
page, as described under "2–2b: Pitch EG," on page 55.
Differences from the other EGs
The Pitch EG is different from the Filter and Amp EGs in
several ways:
• The single Pitch EG is shared by both Oscillator 1 and
Oscillator 2.
• The Sustain level is always 0.
• The Level modulation has two AMS sources instead of
one, and the Time modulation has one AMS source
instead of three.
Pitch EG is also an AMS source
You can use the Pitch EG as an AMS source to modulate
other parameters, just like the keyboard tracking and LFOs.
Simply select the Pitch EG in the AMS list for the desired
parameter.

2–9a: EG Reset
AMS (EG Reset AMS)
This selects an AMS source to reset the EG to the start point.
For instance, you can use a tempo-synced LFO to trigger the
EG in a repeating rhythm. This reset is in addition to the
initial note-on, which always causes the EG to start.
For a list of AMS sources, see "Alternate Modulation Source
(AMS) List" on page 901.
Threshold
This sets the AMS level which will trigger the EG reset.
Among other things, you can use this to adjust the exact
point in an LFO's phase at which the EG will be reset,
effectively controlling its "groove" against other rhythmic
effects.
When the threshold is positive, the EG triggers when
passing through the threshold moving upwards. When the
threshold is negative, the EG triggers when passing through
the threshold moving downwards.
Note: With some LFO shapes, and with faster LFO speeds,
the LFO may not always reach the extreme values of +99 or
-99. In this case, setting the Threshold to these values may
cause inconsistent behavior, or may mean that the EG
doesn't reset at all. If this happens, reduce the Threshold
until the EG triggers consistently.
