This selects the start and end points of the loop, and whether
the loop is forwards only or forwards-backwards.
The first three selections, 0

forwards only. For instance, when Loop Type is set to 1  3,
the EG will play as follows: 0, 1, 2, 3, 1, 2, 3, 1, 2, 3 etc.
The last two selections, 0  3 and 1  3, are forwards-
backwards. For instance, with the 1

3 setting, the EG will
play as follows: 0, 1, 2, 3, 2, 1, 2, 3 etc.
Loop Repeat [Off, 1…126, INF]
Off: When this is set to Off, the EG will not loop at all.
1-126: The EG will loop the specified number of times, and
then hold at point 3 until the note is released.
INF: The EG will loop as long as the note is held, and then
move to point 4 when the note is released.
1–6c: X-Y Envelope
Like the Filter, Amp, and Pitch EGs, the X-Y Envelope has a
total of five points. Since the X-Y Envelope can loop,
however, the points are labeled differently; instead of names
like attack and decay, they are simply numbered 0–4.
Sustain and Release
When the EG is in the middle of a loop, there is no “sustain”
point per se. However, if the EG has already completed the
specified number of
Loop Repeats , or if Loop Repeat is
Off, it will sustain at Point 3 until release.
At release, the EG always moves to Point 4.
Hold and Transition times
The Hold Time sets how long the EG lingers at each point,
and the Transition time sets how long it takes to go from the
selected point to the next.
For instance, the graphic below shows the succession of
Hold and Transition times when the Loop Type is set to
1
 3. For clarity, only the Y axis positions are shown.
X-Y Envelope times, Loop Type = 1

3
The transition from Point 3 into the loop always uses Point
3’s Transition time, regardless of the Loop Type.
Points 0, 1, and 2’s Transition times, however, work in
reverse when moving backwards during a forwards-
backwards loop. It’s as if you were re-tracing the EG shape
in reverse.
For instance, in the backwards section of a loop, moving
from Point 2 to Point 1 uses Point 1’s Transition time.
Forwards-Backwards Loop, Loop Type = 1

X-Y [Off, 0…4]
This horizontal row of radio buttons lets you edit the
selected point’s X-Y position using the X-Y Control.
Just press the point’s radio button, move the X-Y Control to
the desired location. When you’re finished, press the Off
radio button again.
When you are not editing the EG’s X-Y positions, you
should leave this set to Off, to avoid inadvertent changes to
the EG.
Point 0
Position
In addition to editing the X and Y parameters with the
standard data entry controls, you can also simply use the X-
Y Control to set the position, as described under “X-Y,”
above.
X [–127…+127]
This sets the point’s position on the X axis.
Y [–127…+127]
This sets the point’s position on the Y axis.
Hold Time
This sets the length of time that the EG will stay on Point 0,
before moving to Point 1. You can set the Hold Time in
either seconds/milliseconds or rhythmic values, depending
on the setting of the EG’s Mode parameter.
Time [0ms…60sec]
This parameter lets you set the Hold Time in seconds and
milliseconds. It applies only when the Mode is set to Time.
(Base Note) [Off, … ]
This menu sets a basic rhythmic value for the Hold Time ,
relative to the system tempo. The values range from a 32nd
note to a whole note, including triplets.
This parameter applies only when the Mode is set to Tempo .
x (Multiply Base Note by…) [01…32]
This multiplies the length of the Base Note . For instance, if
the Base Note is set to a sixteenth note, and the multiplier is
set to 3, the Hold Time will last for a dotted eighth note.
Transition
This sets the length of time that the EG takes to move from
Point 0 to Point 1.
When the Loop Type is set to 0

3, this also sets the time
that it takes to move from Point 1 to Point 0 during the
backwards section of the loop.
