Roland XV-3080 用户手册

These parameters determine the amount of pitch enveloping 
– changes to your basic pitch settings that occur over time – 
the effect of velocity on the pitch envelope, and the basic 
characteristics of the pitch envelope itself.

fig.4-23.e

This determines the amount of pitch enveloping to be used – 
higher settings result in more extreme enveloping. Negative 
(-) settings invert the direction of the changes made by the 
Pitch Envelope.

Adjust this parameter when you want your keyboard 
playing dynamics (velocity) to affect the amount of pitch 
enveloping. With higher settings, there will be a greater 
difference in the amount of enveloping when notes are 
played softly or when they’re played hard. Negative (-) 
settings will reverse the direction of change.

Use this parameter when you want the keyboard location of 
notes to affect times T2–T4 of the pitch envelope. Higher 
values for this parameter will cause more extreme changes to 
the T2–T4 settings as you play further away from Middle C 
(C4) – at Middle C itself, your original T2–T4 settings are in 
effect. Positive (+) settings cause the times to be shortened for 
notes above Middle C. Negative (-) settings cause the times 
to be lengthened for notes above Middle C.

Use this parameter when you want keyboard playing 
dynamics (velocity) to affect T1 (Time 1) of the pitch 
envelope. With higher settings, the T1 value will change 
more significantly depending on whether you play softly or 
with greater force. With positive (+) settings, greater 
keyboard velocity will reduce the T1 setting. With negative (-
) settings, greater keyboard velocity will increase the T1 
setting.

Use this parameter when you want keyboard playing 

dynamics (velocity) to affect T4 (Time 4) of the pitch 
envelope. With higher settings, the T4 value will change 
more significantly depending on whether you play softly or 
with greater force. For positive (+) settings, keyboard 
velocity will reduce the T4 setting. For negative (-) settings, 
keyboard velocity will increase the T4 setting.

These settings determine the times over which the basic pitch 
settings will change from one pitch envelope level (L1–L4) to 
the next.

Each pitch envelope level value determines an amount of 
change to be applied to the Tone’s basic pitch.

The settings for the TVF (Time Variant Filter) allow you to 
change a Tone’s timbral content by altering its brightness or 
thickness.

This selects a filter type. A filter typically reduces, or 
attenuates, a specific frequency range within a Tone in order 
to accentuate its other frequencies.

 No filter is used.

 A Low Pass Filter reduces the volume of frequencies 

above the cutoff frequency in order to round off, or un-
brighten, the sound. This is the most common filter used in 
synthesizers.

 A Band Pass Filter reduces the volume of frequencies 

below and above the cutoff frequency range. This is most 
effective when creating sounds with strong characteristics 
since it can accentuate a desired range of frequencies 
anywhere in the sound.

 A High Pass Filter reduces the volume of the 

frequencies below the cutoff frequency. This is suitable for 
creating percussive sounds by rolling of their lower 
frequencies, thus emphasizing their higher ones.

 A Peaking Filter emphasizes frequencies around the 

cutoff frequency by raising their level. You can use this to 
create wah-wah effects by employing an LFO to change the 
cutoff frequency cyclically.

 Low Pass Filter 2. This reduces the volume of all 

frequencies above the cutoff frequency. This differs from LPF 
in that you can control the amount of the reduction using the
