MODULATION

(Low-Frequency

Oscillator)

All

the

controllers

mentioned

up

to

this

point

have

generated

non-repetitive

voltages;

the

keyboard

generates

a

static

voltage

level

for

each

key,

and

the

contour

generators

output

a

"one-shot"

voltage

pattern.

Musical

sounds

demand

repetitive

changes

such

as

vibrato,

trills,

or

tremolo.

On

The

Source,

repetitive

changes

are

controlled

by

a

low-frequency

oscillator

This

oscillator

generates

waveforms

exactly

like

the

audio

oscillators,

but

operates

in

a

much

lower frequency

range

(1

cycle

every

3

seconds

to

30

cycles

per

second).

The

output

of

this

oscillator

is

a

triangular

or

square

waveform.

This

output

voltage

may

be

routed

to

the

control

inputs

of

the

oscillators

and/or

filter,

through

the

Mod

wheel.
