Changing The Tone (Filter) Of A Rhythm Tone (Tvf) - Roland XV-88 Owner's Manual

V-Sens (Pitch Envelope Velocity Sensitivity)
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.
V-T1
(Pitch Envelope Time 1 Velocity Sensitivity)
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.
V-T4
(Pitch Envelope Time 4 Velocity Sensitivity)
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.
L0 (Pitch Envelope Level 0)
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.
T1–T4 (Pitch Envelope Time 1–4)
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).
L1–L4 (Pitch Envelope Level 1–4)
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.

Chapter 6. Creating Rhythm Sets
Changing the Tone (Filter) of a
Rhythm Tone (TVF)
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.
TVF FILTER
fig.06-21
Type (Filter Type)
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.
OFF: No filter is used.
LPF: 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.
BPF: A Band pass filter reduces the volume of frequencies
below and above the cutoff frequency range. This can be
useful when creating distinctive sounds.
HPF: 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.
PKG: 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.
LPF2: 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.
LPF3: 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.
