PB-1

A.

Keyboard

Circuit

Consists

of

a

constant

current

source

fed

to

the

keyboard

resistors

which

provids

specific

voltage

drops

when

keyboard

are

pressed.

This

voltage

is

fed

to

an

S

where

it

is

held

until

another

voltage

is

produced

by

depressing

another

key.

The

output

of

this

circuit

is

used

for

controlling

the

VCO's

and

VCF.

A

second

circuit

generates

trigger-pulses

by

OP-19

Contains:

±10V

Regulator,

PHONES,

LFO-1,

LFO-2,

S/H,

and

NOISE

GEN,

circuits.

A.

±10V

Regulator

The

constant

voltages

+14V

and

-14V

of the input

are

converted

into

highly

stable

D.C

outputs:

+10.00V

and

-10.00V.

Generally

speaking,

the

more

accurate

the

adjustment

(the

more

zeroes

after

the

decimal

point)

the

more

accurate

the

VCO

tracking

will

be.

B.

PHONES

Controls

the

LEVEL

without

any

relat/on

to

the

OUTPUT

LEVEL

of

VCA.

C.

LFO-1

This

is

a

Low

Frequency

Oscillator

to

produce

both

inverted

and

non-inverted

Sawtooth

waveforms

with

a

phase

difference

of

180°.

D.

LFO-2

Produces

Sine

wave,

Square

wave

(inverted

and

non-inverted),

and

Triangular

wave

for

use

in

modulation,

and

TRIG,

for

AR.

and

ADSR.

DELAY

TIME

utilizes

Sine

wave

alone.

E.S/H

This

circuit

is

for

sampling

voltages

from

different

waveforms,

using

LFO-1

(

|)j^

),

LFO-2

(

AA

),

and

RANDOM

(NOISE)

for

its

input

source.

The

output

can be

used

to

control

VCO-1

and

the

VCF

for

getting

special

effects.

Sample

time

decides

the

timing

of

the

sampling

operation.

Lag

time

uses

an

RC

filter

to

add

lag

to

quick

voltage

changes.

F.

NOISE

GEN.

The

sound

source

here

is

the

white

noise

produced

at

the

B-E

(base

—

emitter)

junction of

a

reverse

biased

transistor.

It

is

amplified

and,

through

filtering,

is

changed

to

either

WHITE

or

PINK

at

the

output.

3-2-2.

VCO

BOARD

ASSEMBLY

VCO-1

A

VCO

is

an

oscillator

whose

frequency

is

controlled

by

a

control

voltage

coming

from

the

Keyboard

or

other

external

sources.

Incoming

linear

control

voltages

are

first

converted

into

voltages

with

an

exponential

increasing

ratio.

The

oscillator

itself

is

a

sawtooth

generator.

Wave

shapers

convert

this

sawtooth

to

triangle

and

square

waves.

This

assembly

functions

as

VCO-1,

and

is

capable

of

synchronous

driving

of

VCO-2

by

means

of

the

synchronizing

pulses

generated

in

this

assembly.

OP-20

VCO-2,

RING

MOD.

VCO-2

is

an

oscillator

which

is

about

the

same

as

VCO-1.

With

the

Keyfollower

turned

to

OFF,

the

frequencies

generated

here

are

held

at

a

constant

level

and

not

subject

to

follow

the

keyboard.

RING

MOD.

(ring

modulator)

is

a

circuit

for

producing

sounds

of

special effect,

such

as

bell-like

sounds.

The

sum

and

difference

of

the

two

input

frequencies

are

the

only

frequencies

to

appear

at

the

output

of

the

ring

modulator.

OP-21

VCF,

BAND

PASS

FILTER,

VCA

The

VCF

is

a

Voltage

Controlled

Filter

and

can

be

used

either

as:

LPF,

BPF, and

HPF.

The

LPF

consists

of

a

ladder

type

network

of

diode

chain

transistors,

and

is

capable

of

generating

by

itself

fre

quencies

of

a

wide

range

so

that

it

can

be

used

to

make

musical

scales

following

the

keyboard

manuals.

Band

Pass

Filter

is,

unlike

the

others,

a

fixed

filter

and

not

voltage

controlled.

The

VCA

has

its

gain

of the

control

voltage

applied

to

the base of

the

transistor

in

this

circuit.

Fuses

When

replacing

fuses,

use

only

those

rated

as

shown

on

the

caution

label

on

the

circuit

board.

Repeatedly

blown

fuses

indicate

something

wrong

with

the

circuits.

Using

larger

value

fuses

will

only

aggravate

this

condition

and

will

result

in

damage

to

the

circuits.

4-2.

Adjustment

Calibration

adjustments

should

be

done

in

the

order

given.

Accurate

adjustment

can

be

assured

only

if

the procedures

are

followed

exactly

as

given.

4-3.

Slide

Switch

Double

check

the

positions

of

slide

switches.

Slide

switches

set

in

between

positions

is

the

largest

cause

of

malfunction

of

this

synthesizer.

4-4.

Replacement

of

parts

Use

only

those

as

specified

in

the

Parts

List.

Use

of

parts

other

than
