OSC

The

oscillator

consists

of

a

master

oscillator

(8MHz)

and

a

divider

IC35.

The

{C35

divides

8MHz

by

two,

four

or

eight

according

to

a

position

of

RANGE

(4',

8’,

16’)

on

the

panel

and

feeds

it

to

DCOs

IC33

and

1C34

which

are

16-bit

Programmable

Interval

Timers.

DCO

Each

of

three

counters

in

one

Timer

divides

OSC

frequency

by

a

number

de-

fined

by

a

divide

data

represented

on

the

data

bus

of

the

slave

CPU

IC29.

The

divide

data

is

the

sum

of

a

key

number

and

the

outputs

from

LFO,

Bender,

Portamento

and

Tune

for

a

particular

note.

The

resultant

the

output

of

each

counter

will

be

a

rectangular

audio

frequency.

D/A

CONVERTER

In

controlling

voices

the

slave

CPU

does

not

output

each

parameter

indepen-

dently,

rather,

it

integrates

some

of

parameters

that

are

needed

for

a

parti-

cular

destination

(DCO,

VCF

or

VCA)

and

represents

them

as

a

12-bit

data

(upper

6

bits

at

PBO—PB5

and

lower

6

bits

at

PC2—-PC7).

The

data

is

con-

verted

into

an

analog

voltage

which

is

conditioned

and

routed

to

the

tion

GENERATOR

1/2MC5534A

(C4,

8,

12)

MC5534

(IC

4,

8

and

12)

is,

with

a

given

rectangular

at

CLK

IN,

capable

of

generating

three

different

waveforms;

divided

by

two

rectangular,

sawtooth

and

variable-width

rectangular

(Pulse

Width

Modulated).

There

are

three

versions

in

MC5534

series;

of

these

MC55344A

is

the

latest

version

containing

complete

two

identical

circuits.

See

Parts

Change

Notes

in

the

Parts

List

section

for

detail.

SUB

OSCILLATOR

This

is

self-explaining

from

the

figure.

The

output

amplitude

being

variable

to

a

change

of

collector

supply

voltage

(SUB

LEVEL).

SAWTOOTH

For

sawtooth

and

PWM

waveforms,

DCO

CV

is

applied

from

the

slave

CPU

in

addition

to

DCO

output.

The

DCO

CV

will

keep

the

sawtooth

and

pulse

amplitude

nearly

constant

(approx.

12Vp-p)

over

the

frequency

range

(detailed

Jater).

Therefore,

DCO

CV

includes

LFO,

BENDER,

PORTAMENTRO

and

TUNE

data

as

well

as

key

value,

but

it

does

not

contain

RANGE

data;

the

DCO

CV

sees

RANGE

at

the

output

of

4052

(1C2,

6

or

10)

which

selects

among

R85,

86

and

87

in

accordance

with

RANGE

code

(PF6

and

7

of

the

slave

CPU).

The

DCO

CV

charges

C54

through

R85

(if

16’)

and

discharges

through

transistor

E

on

the

positive

going

edges

of

DCO.

If

the

RC

time

constant

(C54

and

R85,

86

or

87)

remains

unchanged,

sawtooth

amplitude

becomes

low

at

4’,

The

same

principle

applies

to

key

range

over

the

keyboard;

the

output

amplitude

de-

creases

as

the

note

runs

high.

Therefore,

DCO

CV

is

made

to

become

higher

in

proportion

to

key

number.

PULSE

MODULATED

WAVE

At

ICB

input,

sawtooth

wave

is

compared

with

PWM

CV

that

determines

the

pulse

duratation

of

ICB

output;

duty

ratio

is

50%

at

+6V

PWM

CV

and

95%

at

+0.6V.

With

PWM

OFF,

PWM

CV

is

—0.8V;

this

can

swing

and

keep

ICB

output

to

High,

disabling

the

rectangular.

VCF,

VCA

A1QH80017A

is

a

one-chip

VCF

and

VCA.

Both

VCF

and

VCA

are

indivi-

dually

controlled

by

the

several

parameters

integrated

into

one

voltage:

VCF

CV

contains

CUT

OFF

(VCF)

frequency,

ENV,

LFO,

Key

follow

and

Bender;

VCA

CV

includes

ENV

and

GATE.
