instRUCTIONS

The

five

separate

sections

which

comprise

the

Roland

GR-500

are

the

Guitar,

Polyensemble,

Bass,

Solo

Melody,

and

External

Synthesizer

Sections.

The

External

Synthesizer

Section

is

essentially

an

interface

to

any

of

the

popular

brands

of

synthesizer.

Each

of

the

five

sections

of

the

GR-500

may

be

played

individually

or

in

any

combination.

Each

section

offers

unlimited

freedom

of

expression

and

unsurpassed

controllability.

Roland

has

created

a

name

for

this

new

level

of

performance

capability.

It

is

the

word

“paraphonic,”

derived

from

“parallel”

plus

“phonic.”

Nearly

all

of

the

controls

on

both

the

Guitar

Controller

(Guitar)

and

the

GR-500

Synthesizer

are

grouped

and

labeled

to

fall

within

these

five

sections.

Output

from

each

of

the

five

sections

of

the

GR-500

Guitar

Synthesizer

can

be

channeled

separately

or

in

combination,

through

any

of

three

independent

output

jacks.

Remarkable

flexibility

is

afforded

by

this

capability

of

connecting

each

output

to

the

amplifiers

most

appropriate

for

its

source.

It

is

also

possible

to

channel

all

sounds

through

a

single

amplifier

by

using

the

MIX

OUT

jack,

which

contains

the

outputs

of

all

five

sections.

A

headphone

jack

also

contains

the

sound

from

all

five

sections,

and

enables

you

to

perform

or

practice

privately.

for

individual

differences

in

Examples

of

these

are

intensity,

hardness

of

the

picking

region,

string

and

bridge height

(clearance

between

Because

of

these

factors,

trigger

occur.

This

results

in

intermittent

When

But

if

The

WHAT

IS

AN

Three

of

the

essential

qualities

by

which

we

distinguish

a

sound

are

pitch,

timbre,

and

envelope

(rise

and

fade

of

a

sound).

Pitch,

or

course,

is

represented

by

frequency.

Timbre

is

determined

by

the

harmonic

content,

or

pattern

of

overtones

present.

The

produced

by

strings

will

fade

away

after

a

certain

length

of

time,

even

if

the

string

is

picked

intensely

(Fig.

P-1).

This

is

not

true

in

the

case

of

such

as

an

organ

where

sound

is

maintained

as

long

as

a

key

is

held

down

(Fig.

This

"continuing"

of

a

sound

is

referred

to

as

SUSTAIN,

and

the

volume

level

at

which

the

tone

continues

to

sound

is

called

the

Raising

increases

the

Note

that

when

not

therefore,

adjustment

no

Guitarists

everywhere

have

strongly

desired

to

be

able

to

use

their

instruments

to

play

bass.

The

Roland

GR-500

Guitar

Synthesizer

makes

this

dream

a

reality.

And

it

does

so

with

greater

versatility

and

flexibility

than

you

might

imagine.

Through

its

envelope

generator

and

percussion

controls,

the

Bass

Section

offers

unlimited

performance

possibilities,

Its

“İast-note-priority

system

enables

you

to

use

the

Bass

Section

to

play

duets.

Last-

note-priority

means

that

the

bass

note

ultimately

heard

corre-

sponds

with

the

last

string

picked.

The

Bass

Section

is

activated

and

its

volume

controlled

by

an

on/off

switch

and

a

volume

located

on

the

guitar

con-

troller.

The

Bass

Section

may

be

played

in

combination

with

any

other

sections

of

the

guitar

synthesizer.
