DELAY

VIBRATO

This

program

makes

it

possible

to

add

delay

vibrato

effects

to

virtually

any

instrument

or

sound.

When

the

input

signal

exceeds

a

programmed

trigger

level,

the

vibrato

effect

is

cancelled

and

then

gradually

builds

up

to

the

programmed

depth.

1.

TRIGGER

LEVEL.

Range:

1

-

100%

Determines

the

input

signal

level

at

which

the

vi-

brato

effect

is

cancelled

and

begins

to

build

up

again.

2.

VIBRATO

DELAY.

Range:

1

-

30,000

msec

Determines

how

long

the

vibrato

effect

is

cancelled

once

triggered.

3.

VIBRATO

RISE

TIM

E.

Range:

5

msec

-

32,000

msec

Determines

how

long

it

takes

for

the

vibrato

effect

to

reach

maximum

depth

after

the

VIBRATO

DELAY

time

has

elapsed.

4.

VIBRATO

FREQUENCY.

Range:

0.1

-

20.0

Hz

This

parameter

sets

the

frequency

(speed)

of

the

vibrato

effect.

5.

VIBRATO

DEPTH.

Range:

0

-

100%

Sets

the

depth

(strength)

of

the

vibrato

effect.

6.

MIDI

TRIGGER.

Range:

ON,

OFF

When

ON,

a

KEY

ON

signal

from

an

external

MIDI

keyboard

can

be

used

to

trigger

the

vibrato

effect.

PARAMETRIC

EQ

This

program

permits

variation

of

the

input

signal

frequency

response

over

an

extremely

broad

range.

1.

HPF.

Range:

THRU,

32

Hz

—

1.0

kHz

This

sets

the

cutoff

frequency

of

the

high-pass

filter.

Frequencies

below

the

set

frequency

are

rolled

off

at

a

rate

of

6

dB/octave.

When

set

to

THRU,

the

HPF

is

OFF.

2.

MID

FRQ.

Range:

315

Hz

-

4.0

kHz

Determines

the

center

frequency

of

the

midrange

equalization

band.

The

midrange

frequency

can

be

set

in

1

/6

octave

increments.

3.

MID

GAIN.

Range:

—15

-

+15

dB

Determines

the

amout

of

boost

or

cut

applied

to

the

midrange

equalization

band.

4.

MID

Q.

Range:

0.5

-

5.0

Sets

the

"Q"

(Quality

factor

=

bandwidth)

of

the

midrange

EQ

band.

The

higher

the

value,

the

narrower

the

bandwidth.

5.

HI

FRQ.

Range:

800

Hz

-

8.0

kHz

Determines

the

center

frequency

of

the

high

-fre-

quency

equalization

band.

6.

HI

GAIN.

Range:

—15

-

+15

dB

Determines

the

amount

of

boost

or

cut

applied

to

the

high

-frequency

equalization

band.

7.

HI

Q.

Range:

0.5

-

5.0

Sets

the

"Q"

(Quality

factor

=

bandwidth)

of

the

high

EQ

band.

The

higher

the

value,

the

narrower

the

bandwidth.

8.

LPF.

Range:

1

kHz

-

11

kHz,

THRU

Determines

the

cutoff

frequency

of

the

low-pass

filter.

9.

DELAY.

Range:

0.1

-

400.0

msec

Sets

the

delay

time

of

equalized

signal

following

the

direct

signal.
