The delay time of the following three effects is determined by the "Tempo" and "Note" parameters, so you can easily match the delay time to the tempo of the music. Tempo Mono Echo (TmpEchl) Creates a single delay with stereo output. 1in/2out Tempo Stereo Echo (TmpEch2) 2in/2out Produces a separately processed left and right channel stereo echo. Tempo Quad Echo (TmpEch4) 2in/2out This program produces an echo effect that used to be possible only with four delay effect machines. Four delay lines are controlled in pairs. • How to input the "TEMPO" parameter One of the following five methods can be used to input the "Tempo" parameter. • Manual Input You can set the Tempo like any other parameter by inputting a numerical value in the edit mode. • Tap Input (Function Key) The tempo can also be set by pressing a function key twice in succession in the edit mode. The interval between the two key operations determines the Tempo value. • Tap Input (Footswitch) Instead of a function key, a foot switch conected to the rearpanel TRIGGER terminal can also be pressed twice in succession. • MIDI Clock Input The Tempo value may also be set using the MIDI clock of a connected device. • MIDI Control Change The Tempo parameter can also be controlled via MIDI control change messages like any other parameter. The input methods available depend on the setting of the "Trig." parameter. SETTING OF "Trig."

To set a delay time matching the tempo of the music, you just press the foot switch twice for a one-beat interval. This eliminates a troublesome parameter setting in the edit mode. What you actually set by tap input is not the delay time but the tempo. The delay time then is calculated based on this Tempo value and the Note value, which must be set in advance. When you tap input using the "TapKey" display, a bar graph indication shows the time elapsed since the first function key or foot switch operation. One bar equals 250 msec (50 msec per vertical line). Please note that the bars will disappear, if the maximum allowable delay time is exceeded before you press the function key or foot switch a second time. • Tap Input using a function key Tempo EJ=12I3 • A P [ 4,1= 9ci "Tempo" value after Tap Input.

The
delay
time
of
the
following
three
effects
is
determined
by
the
"Tempo"
and
"Note"
parameters,
so
you
can
easily
match
the
delay
time
to
the
tempo
of
the
music.

How
to
input
the
"TEMPO"
parameter
One
of
the
following
five
methods
can
be
used
to
input
the
"Tempo"
parameter.
Manual
Input
You
can
set
the
Tempo
like
any
other
parameter
by
inputting
a
numerical
value
in
the
edit
mode.
Tap
Input
(Function
Key)
The
tempo
can
also
be
set
by
pressing
a
function
key
twice
in
succession
in
the
edit
mode.
The
interval
between
the
two
key
operations
determines
the
Tempo
value.
Tap
Input
(Footswitch)
Instead
of
a
function
key,
a
foot
switch
conected
to
the
rear
-
panel
TRIGGER
terminal
can
also
be
pressed
twice
in
succession.
MIDI
Clock
Input
The
Tempo
value
may
also
be
set
using
the
MIDI
clock
of
a
connected
device.
MIDI
Control
Change
The
Tempo
parameter
can
also
be
controlled
via
MIDI
control
change
messages
like
any
other
parameter.
The
input
methods
available
depend
on
the
setting
of
the

You
can
set
the
delay
time
following
the
tempo
of
the
music
by
pressing
a
function
key
or
a
connected
foot
switch
twice
in
succession.
To
set
a
delay
time
matching
the
tempo
of
the
music,
you
just
press
the
foot
switch
twice
for
a
one
-beat
interval.
This
eliminates
a
troublesome
parameter
setting
in
the
edit
mode.
What
you
actually
set
by
tap
input
is
not
the
delay
time
but
the
tempo.
The
delay
time
then
is
calculated
based
on
this
Tempo
value
and
the
Note
value,
which
must
be
set
in
advance.
When
you
tap
input
using
the
"TapKey"
display,
a
bar
graph
indication
shows
the
time
elapsed
since
the
first
function
key
or
foot
switch
operation.
One
bar
equals
250
msec
(50
msec
per
vertical
line).
Please
note
that
the
bars
will
disappear,
if
the
maximum
allowable
delay
time
is
exceeded
before
you
press
the
function
key
or
foot
switch
a
second
time.
