Roland XP-30 사용자 설명서

Set this parameter when you want your keyboard playing dynamics 
to affect the amount of pitch change. For higher settings, there will 
be a greater difference between softly and strongly played notes. 
Negative (-) settings will invert the direction of change.

These parameters determine how keyboard playing 
dynamics will affect the times of the Pitch Envelope.

Use this parameter when you want keyboard playing 
dynamics (velocity) to affect T1 (time) of the Pitch Envelope. 
For higher settings, there will be a greater difference between 
softly and strongly played notes. For positive (+) settings, 
keyboard velocity will speed up the T1 time. For negative (-) 
settings, keyboard velocity will slow down the T1 time.

Use this parameter when you want keyboard playing 
dynamics (velocity) to affect T4 (time) of the Pitch Envelope. 
For higher settings, there will be a greater difference between 
softly and strongly played notes. For positive (+) settings, 
keyboard velocity will speed up the T4 time. For negative (-) 
settings, keyboard velocity will slow down the T4 time.

Use this parameter when you want the keyboard location of the 
note to affect the times (T2–T4) of the Pitch Envelope. Higher 
settings of this parameter will cause greater time change 
relative to the envelope time at middle C (C4). Positive (+) 
settings will cause the time change to become shorter for notes 
to the right of middle C. Negative (-) settings will cause the 
time change to become longer for notes to the right of middle C.

These parameters set the Pitch Envelope (the shape of the 
pitch change over time).

fig.3-42.e

Set the times over which the pitch will change from one point 
to the next.

Set the amount of pitch change (relative to the basic pitch) for 
each point.

The parameters in this group allow you to use the TVF (Time 
Variant Filter) to modify the frequency characteristics of the sound.

These parameters are the TVF filter settings.

Select the filter type.

filter not used.

Cut the frequencies above the 
Cutoff Frequency. This is the most 
common type of filter used in 
synthesizers.

Pass only the frequencies in the 
area of the Cutoff Frequency.

Cut the frequencies below the 
Cutoff Frequency.

Emphasize the frequencies in the 
area of the Cutoff Frequency.

Set the frequency of the filter.

Emphasize the frequencies in the area of the Cutoff 
Frequency. For some settings, excessive levels can cause 
oscillation and distortion.

fig.3-43.e

Use this parameter when you want the Cutoff Frequency to 
be affected by the keyboard position.
Higher values will result in greater change relative to middle 
C (C4). Positive (+) settings will make the Cutoff Frequency 
rise as you play further the right of the keyboard. Negative (-
) settings will make the Cutoff Frequency fall.

Adjust the depth of the TVF envelope. Higher settings will 
result in greater change. Negative (-) values will invert the 
envelope.
