Pitch: Pitch EG
Here you can make settings for the pitch EG, which creates time-
variant changes in the pitch of the oscillators. The depth of pitch
change produced by these EG settings on the oscillators is
adjusted by the “Intensity (AMS1/2 Intensity)” parameter (see
page 63).
Diagram
The diagram on top of the page shows the Pitch envelope line.
Level
These parameters specify the amount of pitch change. The actual
amount of pitch change will depend on the “Intensity (AMS1/2
Intensity)” parameter (see below). For example, with an “Inten-
sity” setting of +12.00, a “Level” setting of +99 would raise the
pitch one octave, and a “Level” setting of –99 would lower the
pitch one octave.
Start Level
Specifies the amount of pitch change at note-on.
-99…+99 Parameter value.
Attack Level
Specifies the amount of pitch change when the attack time has
elapsed.
-99…+99 Parameter value.
Release Level
Specifies the amount of pitch change when the release time has
elapsed.
-99…+99 Parameter value.
Time
These parameters specify the time over which the pitch change
will occur.
See diagram above.
Attack Time
Specifies the time over which the pitch will change from note-on
until it reaches the pitch specified as the attack level.
0…99 Parameter value.
Decay Time
Specifies the time over which the pitch will change after reaching
the attack level until it reaches the normal pitch.
0…99 Parameter value.
Release Time
Specifies the time over which the pitch will change from note-off
until it reaches the pitch specified as the release level.
0…99 Parameter value.
Level Modulation
AMS1/2 (Alternate Modulation Source 1/2)
These parameters select the source that will control the pitch EG
“Level” parameters (“AMS (Alternate Modulation Source) list”
on page 77).
Intensity (AMS1/2 Intensity)
These parameters specify the depth and direction of the effect
applied by “AMS1”. With a setting of 0, the levels specified by
“Level” will be used.
For example if “AMS1” is After Touch, pressing the keys to turn
it on will change the “Level” parameters of the Pitch EG. As the
absolute value of “Intensity” is increased, the pitch EG levels will
change more greatly when the key pressure is released. The
direction of the change is specified by “St (Start Level Swing)”
and “At (Attack Level Swing)”. When the key pressure is
released, the pitch EG levels will return to their own settings.
If “AMS1” is set to Velocity, increasing the absolute value of
“Intensity” will produce increasingly wider change in pitch EG
levels for strongly-played notes. The direction of the change is
specified by “St (Start Level Swing)” and “At (Attack Level
Swing)”. As you play more softly, the pitch change will draw
closer to the pitch EG levels.
-99…+99 Parameter value.
St (Start Level Swing)
This parameter specifies the direction of change in “Start Level”
caused by “AMS1/2”. If “Intensity” is a positive (+) value, a set-
ting of + will raise the EG level, and a setting of – will decrease it.
With a setting of 0 there will be no change.
