Key:

INITIAL

DELAY.

Allows

you

to

program

in

an

additional

delay

time.

The

flanged

signal

will

not

appear

until

this

delay

has

elapsed.

Same

as

for

type

presets.

4.

DELAY.

Range:

0.1

-

100

msec.

Key:

F3.

This

sets

the

basic

delay

time

of

the

flange

effect.

This

delay

time

is

then

modulated

periodically

by

the

LFO

(a

Low

Frequency

Oscillator,

with

adjustable

frequency,

built

in

to

the

REV7

specifically

for

varying

delay

times

periodically

in

order

to

produce

a

variety

of

modulation

effects).

This

also

sets

the

delay

time

between

each

repeat.

5.

MODULATION

DEPTH.

Range:

0

—

100%.

Key:

F2.

This

sets

the

amount

by

which

the

LFO

varies

the

delay

time.

At

the

maximum

setting,

the

delay

time

is

varied

by

+1—

4

msec.

6.

MODULATION

FREQUENCY.

Range:

0.1

-

20

Hz.

Key:

Fl.

Sets

the

speed

of

the

LFO,

and

hence

the

rate

at

which

the

delay

time

is

modulated.

7.

FEEDBACK

GAIN.

Range:

0

99%.

Key:

REV

TIME.

Sets

the

amount

of

flange

signal

which

is

fed

back

into

the

circuit

for

further

modulation.

This

controls

the

complex-

ity

of

the

effect,

the

number

of

and

its
