SET UP

YOUR

ODYSSEY

1.

Remove

the

instrument

from

its

shipping

carton.

Do

not

throw

the

carton

a:nd

packing

materials

away.

They

can

be used

to

protect

the

Odyssey

in

transportation.

2.

The

Odyssey

should

be

placed

on

a

firm

support

about

30"

off

the

floor

so

that

its key-

board

is

at

a

comfortable

playing

height.

An

optional

performance

stand

is

available

from

your

dealer.

3.

Connect

the

power

cord

to

a

grounded

110-117 VAC

electrical

outlet.

The

power

switch

in

the

upper

right

corner

of

the

control

panel will

light

up

when

the

Odyssey

is

turned

on.

4.

Like all

electronic

musical

instruments,

the

Odyssey

must

be

connected

to

an

amplifier

and

loudspeaker

system

in

order

to

produce

sounds.

The

phone

jack

labeled

"low

level"

on

the

back

of

the

instrument

is

for

use

with

standard

musical

instrument

amplifiers.

The

smaller

phono

(RCA)

jack

it

is

la-

beled

"high

level"

and

should

be

used in

connecting

your

Odyssey

to

a

tape

recorder,

stereo

amplifier,

or

electronic

organ.

5. A

foot

switch

and

pedal

control

have

been

supplied

with

your

Odyssey.

Connect

these

to

the

rear

panel

jacks

labeled

"pedal"

and

"switch."

The

pedal

is

not

.a

simple

volume

control

such

as

you

are

familiar

with

if

you

have

played

electronic

organs;

it

is an integral

part

of

the Odyssey

and

is

essential for realis-

ing

the

full

potential

of

the instrument.

6.

You

are

now

ready

to

make

music

with

your

Odyssey.

You

can

begin

immediately,

if

you

wish, by

turning

to

the

end

of

this

man-

ual

and

setting

up

any

one

of

the

"patches"

given

there.

There

are

thousands

of

patches

you

can

discover

on

your

own,

and

in

the

pages

of

this

manual

we will

show

you,

in

simplified

form,

how

you

can

discover

some

of

them.

7. Until

you

are

quite

familiar

with

the

range

of

sounds

your

Odyssey

can

produce,

it

will

be

a

good

idea

to

keep

the

tone

controls

of

your

amplifier

set

to

their

"flat"

or

normal

position.

Later

on,

of

course,

you

can

use

them

freely,

together

with

reverberation

if

your

amplifier

provides

it.

HOW

YOUR

ODYSSEY

WORKS

1.

Most

purely

electronic

musical

instruments

work

by

generating

certain

kinds

of

"raw"

sounds

from

circuits

called oscillators.

These

raw

sounds

(not

usually

very

pleasant

or

musi-

cal

sounding

by

themselves)

are

then

modified

by

other

circuits

such

as filters

to

make

them

musically

useful.

In a very general

way,

th

is is

how

your

Odyssey

works,

but

there

are

im-

portant differences.

2.

One

difference

is

that

the

synthesizer

gives

you

complete control

over

every

step

of

the

process

that

turns

a raw

sound

into

an

inter-

esting

musical

event

or

series

of

events.

All

of

the

slide

controls

on

the

upper

half

of

your

Odyssey

control

panel,

for

example,

re-

present

forms

of

sound

modification

that

either

do

not

exist

on

other

electronic

musical

instruments

or

are

buried

deep

inside

where

only

a

serviceman

could

reach

them.

3.

The

biggest

difference,

however,

is

that

with

your

ARP

Odyssey

the

process

of

whitt-

ling a raw

sound

into

something

musically

in-

teresting

can

be

controlled

not

only

manually

but

also, in several

important

respects,

auto-

matically.

This

is

the

principle

of

voltage

control,

which

means

controlling

the

operation

of

your

synthesizer

by

means

of

changing

volt-

ages as well as

changing

slider

positions.

Some

of

the

circuits

in

your

Odyssey

exist

only

in

order

to

produce

such

control

signals.

(Some

of

these

are

the

sample/hold

circuit,

the

two

envelope

generators,

the

L

FO,

and

the

key-

board.

)

4.

In a

modern

manufacturing

plant

many

operations

such

as drilling, milling,

and

lathe

work

will

be

controlled

by

computer.

Most

of

us have seen

at

one

time

or

another

a film

of

this

sort

of

thing-a

piece

of

raw

material

being

locked

into

place

and

machined

to

a

certain

size,

with

holes

of

a

certain

depth,

width,

and

placement-and

so

on.

You

can

think

of

your

Odyssey

as

being

such

an

"assembly

line"

for

the

construction

of

sounds.

it

works: Voltage control

Audio

signals

from

the

two

voltage controlled

oscillators

(VCO

1

and

VCO

2),

the

noise

gen-

erator,

and

are

mixed

and

passed

th

rough

the

volt-

age

controlled filter,

the

high

pass

filter,

and

the

voltage controlled amp-

lifier

before

leaving

the

synthesizer.

The

output

of

the

voltage control-

ed

amplifier

is

connect-

ed

to

the

output

jacks

on

the

back

of

your

Odyssey.

5.

The

ARP

Odyssey

contains

about

a

dozen

separate

pieces

of

equipment

(plus

a

few

extra

controls

such

as

the

portamento

and

pitch

bend

controls

on

the

far

left

of

the

panel.)

These

can

be

connected

to

each

other

in

many

different

ways

by

the

switches

and

sliders

to

produce

thousands

of

different

"assembly

pro-

grams"

or

patches.

Each

patch

requires:

a.

at

least

one

piece

of

equipment

to

gen-

erate

the

raw

material

from

which

the

sound

is

to

be

made;

i.e., a

signal

source.

b.

at

least

one

piece

The

front

panel

of

your

Odyssey

shows

the

general

assembly-line

setup

(Figure

A).

Thus,

to

reach

your

amplifier

and

loudspeaker

system,

a signal

must

pass

through

this"assembly

line."

This is the heart

of

your

Odyssey. By using

the

sliders

and

switches

of

the

audio

mixer,

you

can

select

the

raw

material

for

(VCF),

the

and

the

does

itself;

Set

all

the

controls

on

as

in

Figure B.

There

should

be

no

sound

coming

from

your

speakers

when

the

are

set

Figure

like

this,

even

if

you

press

a

key.

But

the

assembly

line

is

"wide

open"

and

will pass

any

signal

from

the

audio

mixer

in

unchanged

form.

2.

Opening

the

first

slider

under

the

audio

mixer

will give

you

a

steam

-like

hissing

noise

from

the

noise

generator.

The

noise

generator

is

a signal

source,

and

has

one

control,

located

in

the

upper

left

corner

of

the

panel

(Figure

C).

Moving

this

switch

down

will give

you

the

lower-pitched

sound,

like a

distant

waterfall,

of

pink

noise.

These

raw

sounds,

suitably

modified,

are useful in

the

production

of

wind,

thunder,

surf,

and

motor

or

machine

effects.

See

Patch

10,

for

some

of

these.

Close

the

first

slider.

3.

Open

the

second

slider

and

you

will

hear

a

rich

buzzy

tone

from

voltage controlled oscil-

lator 1 {VCO 1).

The

pitch

of

this

tone

can

be

changed

manually

by

the

coarse

and

fine

tuning

sliders

(Figure

D),

and

by

voltage

trol

from

the

keyboard

through

the

two

sliding

attenuators

shown

in

Figure

E.

Experiment

with

the

in

An attenuator

acts

like a

valve,

or

faucet,

to

set

the

amount

of

a

control

signal

that

passes

through

it

to

affect

a

voltage

controlled

device.

An

attenuator is closed

when

it

is all the way down, and open when

it

is

all the way up,

VCO

1

produces

two

kinds

of

output

signals;

you

have

been

listening

to

the

sawtooth signal

(so

called

because

it

is

a

pattern

of

voltage

changes

which

look,

on

a

graph,

like

the

teeth

of

a

saw).

It

is

the frequency with which this

pattern is repeated every second

that

deter-

mines what pitch

you

hear.

You

can

hear

the

puJse

signal

by

oscillator 2

(VCO

VCO

2

is

exactly

like

VCO

except

for

two

things:

a.

VCO

2

does

not

have a

low-frequency

operating

range.

b.

VCO

2

can

be synchronized

to

VCO

1.

Phase

synchronization

of

the

two

oscillators

is

accomplished

by

the

switch

at

the

top

right

in

Figure

I ,

labeled

c'sync

off/on."

When

this

switch

is

on,

the

audio

signal

from

VCO

2 is

forced

to

conform

to

the

frequency

of

VCO

1.

You

can

hear

this

effect

in its raw

form

by

set-

ting

\/CO

1

to

some

relatively

low

audio

fre-

quency

(near

the

"100

mark}

and

slowly

moving

the

coarse

control

of

VCO

2

through

its

entire

range

from

bottom

to

top.

Experiment

also

with

changing

the

frequency

of

VCO

while

leaving

VCO

2 in

about

the

middle

of

its range.

Patches

make

use

of

this

spectacular

At

this

point,

too,

with

the

off,

you

should

practice

tuning

VCO

to

various

by

both

the

open

the

under

again

and

listen·

to

the

The

ring

modulator

is

a signal

modifier,

and

when

you

are

listening

to

it

you

should

think

of

your

assembly

line as

it

is

shown

in

Figure

J.

The

ring

modulator

has

no

controls

of

its

own.

It

produces,

from

the

pulse

outputs

of

VCO

1

and

VCO

2,

a single

complex

output

signal

which

contains

all

the

sums

and

differences

of

the

two

oscillator

frequencies.

This

means

that:

a.

the

raw

sound

produced

from

the

ring

modulator

depends

entirely

on

the

tuning

of

VCO

1

and

VCO

2;

and

to

a lesser

extent

on

the

pulse

width

settings

for

each

one.

Experiment

with

these.

Note in particular

vco 2

that

sounds from the ring mo(fulator do

not

necessarily have any standard musical pitch

in relation to the pitch

of

either oscillator.

(Unless

they

are

synchronized

by

the

"sync"

switch

on

VCO

2;

try

that-)

b.

the

overtones

of

the

ring

modulator

sig-

nal will

not

necessarily

conform

to

the

dard

harmonic

series.

They

may

be

extreme-

ly

complex,

like

those

of

a bell,

chimes,

gongs,

and

other

metallic

or

The

voltage controlled filter

(VCF)

is

a

signal

modifier.

It

alters

the

sound

of

signals

passing

through

it

by

selectively

removing

or

weakening

their

higher

frequencies.

Listening

to

pink

noise,

with

the

settings

as in

Figure

K,

move

the

VCF

freq

slider

slowly

down

as

far

as

it

will go.

You

will

hear

first

the

highest

frequency

components

of

the

noise

weaken

and

disappear,

then

middle

frequencies,

and

finally

even

the

lowest

bass

disappear

until

no

signal

is

audible

at

all.

Try

the

same

procedure

with

signals

from

one

or

both

of

the

VCO's

instead

of

pink

noise.

Raise

the

resonance

slider

about

halfway

up,

as in Figure

L,

and

repeat

the

experiment,

first

with

pink

noise

and

then

with

an

oscillator

signal. With

this

resonance

setting,

the

VCF

"peaks"

sharply

around

a

narrow

range

of

frequencies;

this

is

useful in

creating

various

"wa-wa"

effects.

The

highest

position

of

the

resonance

slider

is

labeled

"self

osc"

(Figure

M

).

In

this

position

the

VCF

is

an

oscillator

just

like

one

of

the

VCO's

and

will

produce

an

output

even

with

all

th

e

input

sliders

on

the

audio

mixer

closed.

In

other words,

it

becomes a signal source

rather than a signal modifier.

The

using

open

the

of

The

high

pass

filter

(HPF)

is

another

signal

modifier.

It

attenuates

frequencies

below

the

setting

of

its

HPF

cutoff

frequency

slider

and

thus

is

exactly

opposite

in its

effects

to

the

VCF

which

is

a

low

pass

filter.*

It

is useful in

eliminating

"boominess"

from

low

bass

notes,

and

in

simulating

certain

instrumental

sounds

(see

Patch

6).

The HPF is

not

voltage con-

trolled.

8.

The

voltage controlled amplifier

(VCA)

is

the

final signal

modifier

stage

of

your

Odyssey

"assembly

line."

It governs the volume

of

the

synthesizer's output.

The

most

common

way

of

using

the

VCA

is

to

set

its

VCA

gain

slider

all

the

way

down

and

the

control

attenuator

all

the

way

open.

(See

Figur

e O

on

page

12.)

Thus

the

VCA

will

allow

signals

to

pass

through

only

when

it

is

"instructed"

to

do

so

by

one

of

the

envelope

generators.

They

are

most

often

used

to

program

the

attack

and

of

by

controlling

the

of

the

VCA

or

the

The

two

control

sliders,

one

for

attack time,

and

one

for

release

time.

It

is

referred

to

as

the

The

has

con-

trols

for

and

is

thus

abbreviated

as

By

"sampling"

at

a given

instant

the

signal

voltage

from

the

S/H

the

sample

produces

a series

of

voltage levels.

If

these

in

turn

are used

to

control

a

VCO,

the

result

is

a series

of

pitches.

The

selects

either

the

If

the

give

extra

flexibility

to

your

pitch

control

of

the

oscillators.

Set

the

controls,

to

start

with,

as

in

the

illus-

tration,

and

feed VCO 1

(either

the

sawtooth

or

pulse signal)

into

the

audio

mixer

with

the

VCF,

wide

open.

Depress a

key

and

rotate

the

to

the

right,

then

to

the

left,

then

return

it

to

center.

Release

the

key

and

rotate

knob

again.

Note

that

it

operates

only

when

a

key

is

de-

pressed.

Return

the

knob

to

center.

Raise

the

portamento

slider

about

halfway

and

play a

short

melody;

note

the

"glide"

be-

tween

pitches.

The

position

of

the

portamento

slider

determines

the

speed

of

the

glide;

exper-

iment

with

different

settings.

The

transpose

switch

shifts

the

entire

keyboard

control

up

or

down

by

two

octaves.

Play a

scale up

the

keyboard

with

this

switch

cen-

tered,

and

then

with

the

switch

up,

then

with

the

switch

down.

In

this

way

the

keyboard

can have an

effective

range

of

seven

octaves,

almost

as wide as a

piano.

16 ARP ODYSSEY Keyboard & pedals

The

foot switch

supplied

with

your

Odyssey

is

used

to

turn

on

the

portamento.

Thus

you

can

set

the

portamento

slider

for

a

certain

glide

speed

and

then

turn

it

on

and

off

with

the

foot

switch.

When

the

foot

pedal

is

plugged

into

the

back

of

your

Odyssey,

VCO

2

and

the

VCF

can be

controlled

by

it. (The signal

from

the

5/H

mixer

is

automatically

disconnected

by

insert-

ing

the

foot

pedal jack.) See

Patch

1

and

2

for

examples

of

its use.

Your

Odyssey

keyboard has two-voice capa-

bility.

Feed

both

oscillator

signals

into

the

audio

mixer

and

tune

them

to

unison

while

holding

down

the

lowest

key.

Now

VCO 1

will

follow,

or

"track,"

the

lowest

key

of

any

two

notes

you

play,

and

VCO 2 wil I

track

the

highest

key.

Thus

you

can

play

two

indepen-

dent

pitches

at

the

same

time.

For

examples

of

this

turn

to

page

20

and

begin

with

the

first

patch.

(When

you

are

setting

up a two-voiced

patch,

make

sure

the

"sync,,

switch

is

in

the

"off

11

position.)

HINTS

FOR

GETTING

THE

MOST

OUT

OF

YOUR

ODYSSEY

1.

You

may

tend

at

first

to

think

of

the

con-

trol sliders on

the

Odyssey

as

something

like

stop

tabs

on an

electronic

organ.

That

is,

you

may

be

tempted

to

set

them

in

a

certain

way

and

then

"play"

the

Odyssey

only

from

the

keyboard.

Try

to

overcome

this

temptation.

Use

the sliders in performance. Learn

to

change

the

sounds

you

are

producing

while

you

are

producing

them.

2.

The

patches

given

in

this

manual

are very

basic.

Do

not

hesitate

to

search

for

improve-

ments

and

variations

on

your

own.

In

many

cases a

slight

change

in

the

position

of

a single

control

slider

or

attenuator

can

make

a large

difference

in

the

sounds

you

are

producing.

3. Resist the temptation to merely open

as

many

sliders

as

possible,

as

far

as

possible.

It's a variable synthesizer: vary

it!

ARP ODYSSEY

If

you

just

have

to

start

here:

INSTANT

ODYSSEY

Set up the sound shown on page 19 (opposite).

Play a two-part piece on the keyboard.

If

you hear two voices with pedal control, turn the page and trv more sounds.

If

what

you hear

is

nothing like two voices with pedal

control,

or

if

you don't hear anything,

check the following things;

1

).

Is

the "sync

off/on"

switch turned

off?

(

top

of

Oscillator 2).

If it's on, you'll hear only one voice even though you press down

two

keys.

2).

Is

the "audio

kbd

on/LF

kbd

off"

switch turned on? (top

of

Oscillator 1).

If it's off,

your

first tone source (VCO 1) will be way below

what

your

ear can hear.

3).

Is

the "HPF

cutoff"

slider all the way down? (top

of

High

Pass

Filter).

If it's up, you are

cutting

off

your sound by eliminating

all

but

the very highest overtones.

4).

Is

the "VCA gain" slider down? (top

of

Voltage Controlled Amplifier).

If it's up, you'll hear sound

all

the time, even when you take

your

hand

off

the keyboard.

5). Are the "attack, decay, sustain, release" sliders raised partway? (under

ADSR

Envelope Generator).

If

they're

all

down,

the attack & decay

of

your

note

will make only a tiny blip.

6).

Is

the Odyssey connected to the right amplification system? {back

of

instrument).

The

"low

level"

output

on the back

is

for a standard musical instrument amp;

the "high level"

putput

is

for a tape recorder, stereo amplifier,

or

electronic organ.

7).

Is

the Odyssey plugged in? Turned on?
