LFO 2
The parameters for LFO2 are identical to those for LFO1.
For more information, see the descriptions under LFO1,
above.
3–3b: Common LFO
The parameters for the Common LFO are identical to those
for LFO1. For more information, see the descriptions under
LFO1, above.
Note that while LFO1 and LFO2 are separate for each voice,
the Common LFO is shared by all voices in the Program.
This makes it useful when you want all of the voices to have
an identical LFO effect.

3–4: Filter1 EG
The Filter EG, or Envelope Generator, lets you create
complex, time-varying changes to the cutoff frequencies of
Filters A and B. The parameters on this page control the
shape of the EG. Among other things, 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 filters, use the
Filter EG parameters on the Filter– Filter1(2) Mod. page, as
described under “3–2b: Filter EG,” on page 67.
Filter EG is also an AMS source
You can use the Filter EG as an AMS source to modulate
other parameters, just like the keyboard tracking and LFOs.
Simply select the Filter EG in the AMS list for the desired
parameter.
3–4a: EG Reset
AMS (EG Reset) [List of AMS Sources]
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 [–99…+99]
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
