A

synthesizer

design

may,

in

theory,

incorporate

any

number

of

signal

sources,

modifiers,

and/or

controllers.

Note,

also,

that

the

output

of

a

controller

may

theoretically

be

sent to

the

control

input

of

any

voltage

controlled

device.

The

major

circuits

("modules")

are

explained

here,

roughly

in

order

of

importance

and

occurrence

in

the

signal

path.

SIGNAL

SOURCES

OSCILLATORS

The

Source

has

two

audio

oscillators.

These

oscillators

put

out

electrical

signals

called

waveshapes

or

waveforms,

illustrated

on

the

waveshape

controls.

The

oscillators

generate

waveforms

continuously.

The

completion

of

one

waveform

is

called

a

cycle;

the

number

of

cycles

completed

in

a

specified

time

period

is

the

oscillator's

frequency

and

is

generally

expressed

in

cycles

per

second

(cps)

or

Hertz

(Hz).

If

the

oscillator's

frequency

is

between

20Hz

and

20,000Hz

(20KHz),

human

ears

can

perceive

it

as

pitch.

The

changes

of

oscillator

frequency

produce

the

different

pitches

heard

from

The

Source.

The

oscillators

are

voltage-controlled;

applying

a

positive

voltage

to

their

control

inputs

will

produce

a

positive

change

in

frequency

(the

pitch

will

rise).
