Modifying The Synthesizer Sound; Changing The Volume Envelope (Attack, Decay, Release); Adjusting The Tonal Character (Cutoff, Resonance) - Roland V-Combo VR-09 Owner's Manual

Modifying the Synthesizer Sound

The VR-09 lets you use the top panel harmonic bars to modify the
character of the synthesizer sound.
MEMO
• If you're playing two sounds (split or dual) (p. 27), the settings will
determine which sound is afected.
• If one of the sounds is an organ sound
The bars will operate as harmonic bars for the organ sound.
The synthesizer sound will not change.
• If one of the sounds is a piano sound
The piano sound cannot be changed. The efect will apply
only to the synthesizer sound.
• If two synthesizer sounds are combined
The bars will afect both synthesizer sounds.
• The efect can also be applied when playing a single piano sound.
• For some acoustic sounds (p. 50), DECAY, CUTOFF, and
RESONANCE will have no efect.
Changing the Volume Envelope
(ATTACK, DECAY, RELEASE)
The shape that describes how an instrument's volume changes
over time from the beginning to the end of the note is called the
"envelope. "
On a keyboard instrument, this speciies the way in which the
volume changes from when you press a key until you release the key.
Volume
A D
Note-on
Parameter Explanation
Time from when you press the key until the full
ATTACK
volume is reached
Time over which the volume reaches the SUSTAIN
DECAY
level following the attack
Volume at which the sound is sustained while you
SUSTAIN
continue holding the key
Time over which the sound decays to silence after
RELEASE
you release the key
On the VR-09 you can use the three left-most harmonic bars to
adjust the ATTACK, DECAY, and RELEASE times of the currently
selected sound.
1.
Select a sound from the synthesizer section (p. 13).
2.
Move the bars to adjust the values of the corresponding
parameters.
Bar Value
[ATTACK] bar -64–63
[DECAY] bar -64–63
[RELEASE] bar -64–63

Explanation
Lowering the bar will shorten the attack
time; raising the bar will lengthen the
time.
Lowering the bar will shorten the time
over which the level falls to the SUSTAIN
level; raising the bar will lengthen the
time.
Lowering the bar will shorten the time
over which the sound disappears; raising
the bar will lengthen the time.
When you operate a bar, the current value is shown in the screen.
MEMO
• While the value of a parameter is displayed, you can turn the
[VALUE] dial to adjust the value.
• The value of each parameter is shown as an ofset relative to the
default value originally speciied for each sound. At a value of "0"
(the bar near the center "4" position), that parameter will be in its
original state.
• If you press the [TRANSPOSE] button while the adjustment
screen is shown, the adjustment screen will be held. Press the
[EXIT] button to return to the previous screen.
Adjusting the Tonal Character
(CUTOFF, RESONANCE)
The ilter determines the tonal character of the sound.
You can use the ilter to cut or boost diferent frequency regions of
the sound, thus modifying its character.
Parameter
CUTOFF
RESONANCE
On the VR-09 you can use the two right-most harmonic bars to
adjust the cutof and resonance of the currently selected sound.
1.
Select a sound from the synthesizer section (p. 13).
2.
Move the bars to adjust the values of the corresponding
Time
parameters.
Bar
[CUTOFF] bar
[RESONANCE]
bar
When you operate a bar, the current value is shown in the screen.
* Some settings may produce noise or high-volume sound. Be
careful of the volume of the connected mixer or amp.
MEMO
• While the value of a parameter is displayed, you can turn the
[VALUE] dial to adjust the value.
• The value of each parameter is shown as an ofset relative to the
default value originally speciied for each sound. At a value of "0"
(the bar near the center "4" position), that parameter will be in its
original state.
• If you press the [TRANSPOSE] button while the adjustment
screen is shown, the adjustment screen will be held. Press the
[EXIT] button to return to the previous screen.
Explanation
Frequency at which the ilter takes efect (cutof
frequency)
Amount by which the region near the ilter's cutof
frequency is emphasized
Value Explanation
Speciies the cutof frequency. Lowering
the bar will make the sound darker (more
-64–63
mellow); raising the bar will make the
sound brighter.
Boosts the sound in the region of the
cutof frequency, producing a distinctive
-64–63 tonal character. Lowering the bar will
weaken this character, and raising the bar
will strengthen it.
