Front

Panel Settings

and

Musical

Representations

of

Various

Effects.

Stereo

From

A

Mono

Source

Use

the

E1010

to

delay

the

sound

to

one

of

two

speakers

by

approximately

30

milliseconds.

This

delay

is

too

short

for

the

listener

to

perceive

an

echo,

but

is

long

enough

to

spread

the

image,

simulating

natural

ambience.

This

type

of

stereo

spread

is

not

recommended

when

the

program

is

also

being

combined

to

a

mono

signal.

Double Tracking

Double

tracking

can

be

obtained

by overdubbing

the

exact

same

instrumental

or

vocal

part

on

a

second

track

of

the

tape.

The

sound

achieved

is

never

in

perfect

unison

due

to

minor

variations

in

pitch

and

time.

Double

tracking

is

a

very desirable

and

useful

effect

(also

known

as

chorusing),

especial

ly

for

richening

the

sound

of

vocals,

strings, and

other

instruments.

The

E1010

creates

this

effect

in

real

time,

al

lowing

you

to

precisely

control

the

variables

(pitch

and

time

deviations).

The

delay

time

is

set

for

about

40

milli-

seconds

and

is

automatically

increased

and

decreased

by

the

El

010's

built-in

Modulationcontrols

(Frequency

and

Depth).

Echo

&

Reverb

Effects

"Echo"

and

"reverb"

are

often

confused

with

one

another,

and

there

is

some

overlap

in

their

definitions.

Generally

speaking,

"echo"

consists

of

one

or

more

distinct,

delayed

sound

images

with

recognizable

attacks.

"Reverb"

also

consists

of

multiple

delayed sound

images,

but

they

smear

together

and

have

no

discretely

discern-

ible

attacks.

To

get

a

single

echo

from

the

E1010,

set

the

Feed-

back

control

at

zero, and

adjust

the

time

delay

as

desired.

For

multiple

echoes,

turn

up

the

Feedback

control,

If

the

input

program

has

l

ittle

or

no

sharp

musical

attacks

(i.e.,

legato

string

lines

or

melodic

vocal

backups),

then

the

multiple

echoes

with

a

moderate

to

long

delay

time

can

sound

like

a

reverb.

Rhythmic

Effects

Unusual

rhythmic

effects

can

be

obtained by

setting

the

E1010

for

a

particular

delay, usually

long,

and

play-

ing

against

it.

Thus,

there

is

a

direct

interaction

between

the performer

and

the

sound

equipment.

Whole musical

pieces

can

be

built

around

this interactive

principle.

Vibrato

Vibrato,

while

it

is

a

pitch

change

function,

may

be

created

with

the

E1010

analog delay

l

ine,

and

is

based

on

the

doppler

shift

phenomenon.

It

becomes

a

simple

matter

to

add

vibrato

to

voice

and

to

instruments which

cannot

easily

achieve

the

effect

acoustically.

You

can

use

the

E1010

to

vary

the

pitch

manually

by

moving

the

Delay

time

control

back

and

forth,

or

you

can

set

the

unit

for

automatic

pitch

variation

by

means

of

the

Modulation

Frequency

and

Depth controls.

Pitch

Bend

with

Feedback

In

contrast

to

vibrato,

which

is

a

gradual

and

l

inear

variation

in

pitch,

it

is

possible

to

obtain

sequenced

changes

in

pitch

by

using

a

long

delay

range,

feedback,

and

gradually

changing the

delay

time

(manually

or

with

the

Modulation

controls). A

similar

effect

is

obtained

by

moving

the

Delay

control

up or

down

and

then

holding

the new

setting;

the

pitch

will

increase

or

decrease

to

a

new

value

and

then

hold

at

that

value

until

the

feedback

dies

out

or

a

new

sound

is

introduced.

Flanging

The

term

"flanging"

comes

from

a

practice

known

as

"reel

flanging."

Two

tape

machines

loaded

with

the

exact

same

program

are

started

in

perfect

sync;

then

alternately slowing down

one

tape

machine and

the

other

by

pressing

a

hand

against

the

flanges

of

the

tape

reels

creates

a

series

of

harmonically

related

phase

cancellations

in

the

program.

Unfortunately,

true "reel

flanging"

is

difficult

to

achieve

—

much

less

to

repeat

—

as

there

is

always

the

danger

of

completely

losing

tape

machine

synchronization.

At

best

the

technique

is

cumbersome

because

it

requires

the

full

attention

of

an

operator

other

than

the

mixer

or

performer.

The

E1010

creates

flanging

affects

automatically,

repeatably,

and

without

the

need

for

a

single

tape

machine.

To

obtain

the

effect,

set

the

unit

for

the

shortest

delay

time,

use

modulation

of

the

delay,

and

mix

the

direct

and

delayed

sounds

together;

the varying

delay

signal

beats

against

the

direct

signal

to

create

phase

cancellations

at

harmonics

of

the fundamental.

Hollow

&

Tunnel

Effects

The

E1010

can

make

normal

voice

or

instrumental

parts

sound

like

they

are

coming

from

a

hollow

cavity

or

tunnel.

This

is

done

by setting

the

unit

for

a

short

delay,

and

by

mixing

the

direct

and delayed

sound.

This

is

similar

to

flanging,

but

there

is

no

modulation

so

the

result

is

a

hollow

-sounding

comb

filter.

If

the

delay

time

is

increased

slightly

and feedback

is

added,

then

more

of

a

tunnel

-like

sound

(flutter

-echo)

is

obtained.
