Roland XV-88 User Manual

Keyboard playing dynamics can be used to control the depth 
of the pitch envelope. If you want the pitch envelope to have 
more effect for strongly played notes, set this parameter to a 
positive (+) value. If you want the pitch envelope to have less 
effect for strongly played notes, set this to a negative (-) value.

Use this parameter when you want keyboard playing dynamics 
(velocity) to affect T1 (Time 1) of the pitch envelope. Positive (+) 
settings will cause T1 time to speed up for strongly played 
notes, and negative (-) settings will cause it to slow down.

Use this parameter when you want key release speed to 
impact on T4 (Time 4) value of the pitch envelope. If you 
want T4 time to be speeded up for quickly released notes, set 
this parameter to a positive (+) value. If you want it to be 
slowed down, set this to a negative (-) value.

Specifies the pitch envelope level (L0). Pitch Envelope Level 
0 determines the degree to which the pitch of the sound at 
the instant the key is pressed is altered relative to the 
reference pitch (the Coarse Tune or Fine Tune value set in the 
PITCH page). Positive (+) settings will cause the pitch to be 
higher than the standard pitch, and negative (-) settings will 
cause it to be lower.

Specify the pitch envelope times (T1–T4). Larger values 
result in longer times until the next pitch is reached (for 
instance, T2 controls the time from L1 until L2 is reached).

Set the level (L1–L4) for the pitch envelope. It determines 
how much the pitch changes from the reference pitch (the 
value set with Coarse Tune or Fine Tune on the PITCH page) 
at each point. Positive (+) settings will cause the pitch to be 
higher than the standard pitch, and negative (-) settings will 
cause it to be lower.

Here you can make settings for the TVF (Time Variant Filter). 
This allows you to change a Rhythm Tone’s timbral content 
by altering its brightness or thickness.

fig.06-21

Selects the filter type. A filter is a function that cuts off a 
specific frequency band to change a sounds brightness, 
thickness, and other qualities.

: No filter is used.

: A Low Pass Filter reduces the volume of frequencies 

above the Cutoff frequency (Cutoff parameter) 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 can be 
useful when creating distinctive sounds.

: A High Pass Filter reduces the volume of the 

frequencies below the cutoff frequency. This is suitable for 
creating percussive sounds 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. Although frequency components 

above the Cutoff frequency (Cutoff parameter) are cut, the 
sensitivity of this filter is half that of the LPF. This makes it a 
comparatively warmer low pass filter. This filter is good for 
use with simulated instrument sounds such as the acoustic 
piano.

: Low Pass Filter 3. Although frequency components 

above the Cutoff frequency (Cutoff parameter) are cut, the 
sensitivity of this filter changes according to the Cutoff 
frequency. While this filter is also good for use with 
simulated acoustic instrument sounds, the nuance it exhibits 
differs from that of the LPF2, even with the same TVF 
Envelope settings.

If you set LPF2 or LPF3, the setting for the Resonance 
parameter will be ignored.
