2–8: Pitch EG
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 modulation time 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 P2: OSC/Pitch– OSC1 Pitch
page and OSC2 Pitch page, as described under "2–2b: Pitch
EG," on page 24.
Differences from the other EGs
The Pitch EG is different from the Filter and Amp EGs in
• The single Pitch EG is shared by both Oscillator 1 and
• 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
2–8a: 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, please see "AMS (Alternate
Modulation Source) List" on page 374.
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
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: For several LFO waveform types, or if the LFO cycle is
fast, the LFO output may not always keep up with high
values such as +99 or –99.
In this case, setting the Threshold to these values may cause
inconsistent behavior, or may mean that the EG will not
reset at all. If this happens, reduce the Threshold until the
EG triggers consistently.
Note-on or reset
The envelope moves to a speciﬁed level over the speciﬁed
time, and then moves to the next speciﬁed level over the
speciﬁed time. It produces a modulation signal
corresponding to this movement.
The parameters below let you set four levels, the amount of
time it takes to go from each of the levels to the next, and the
shape (from linear to curved) of each transition.
Each of the four levels can be either positive or negative.
Positive levels will make the pitch (or other AMS
destination) go up from its programmed value; negative
levels will make it go down.
Note that, unlike the Filter and Amp EGs, the Pitch EG's
Sustain Level is always 0.
This sets the initial EG level at note-on.
This sets the level at the end of the Attack time.
Break, short for Break Point, sets the level at the end of the
This sets the level at the end of the Release time.
Higher values mean longer times, as shown below:
