Features
of
the
CP-40
@
The
CP-40
converts
audio
signals
from
microphone
or
line-level
input
sources
into
MIDI
signals
in
real
time
Audio
information,
whether
from
someone
singing
or
playing
an
electric
guitar,
is
instantaneously
converted
into
MIDI
signals.
This
conveniently
allows
you
to
gain
control
over
other
MIDI
devices
—
without
requiring
a MIDI
equipped
keyboard,
or
guitar
controller.
@ Volume and Pitch Changes are also Controllable
The
volume
level
of
input
audio
signals
can
be
output
as
either
Velocity
or
Expression
messages.
Moreover,
since
even
small
shifts
in
pitch
(those
less
than
a
semi-tone)
can
be
transmitted
as
Pitch
Bend
messages,
every
nuance
of
your
music
is
captured.
@ Convenient for input into a Desktop Music System
The
MIDI
data
generated
by
the
CP-40
can
be
used
as
an
input
source
for
real-time
recording
in
Desktop
Music
Systems
(such
as
Roland’s
“TENTRAX”)
or
MIDI
sequencers
(such
as
the
MC-500mk
II).

B IMPORTANT NOTES
When
using
an
AC
adaptor,
be
sure
that
it
is
one
supplied
by
the
manufacturer.
Use
of
any
other
power
adaptor
could
result in
damage, malfunction,
or
electric
shock.
[Power Supply]
@ When making any connections with other devices, always turn off the power to all equipment first;
this will help prevent damage or malfunction.
@ Do not use this unit on the same power circuit with any device that will generate line noise, such as
a motor or variable lighting system.
@ The power supply required for this unit is shown on its nameplate. Ensure that the line voltage of
your installation meets this requirement.
@ Avoid damaging the power cord; do not step on it, place heavy objects on it etc.
@ When disconnecting the AC adaptor from the outlet, grasp the plug itself; never pull on the cord.
@ If the unit is to remain unused for a long period of time, unplug the power cord.
[Placement]
@
Do
not
subject
the
unit
to
temperature
extremes
(eg.
direct
sunlight
in
an
enclosed
vehicle).
Avoid
using
or
string
the
unit
in
dusty
or
humid
areas
or
areas
that
are
subject
to
high
vibration
levels.
@
Using
the
unit
near
power
amplifiers
(or
other
equipment
containing
large
transformers)
may
induce
hum.
@ This unit may interfere with radio and television reception. Do not use this unit in the vicinity of
such receivers.
@ Do not expose this unit to temperature extremes (eg. direct sunlight in an enclosed vehicle can
deform or discolor the unit) or install it near devices that radiate heat.
[Maintenance |
@ For everyday cleaning wipe the unit with a soft, dry cloth (or one that has been slightly dampened
with
water).
To
remove
stubborn
dirt,
use
a
mild
neutral
detergent.
Afterwards,
be
sure
to
wipe
the unit thoroughly with a soft, dry cloth.
@
Never
use
benzene,
alcohol
or
solvents
of
any
kind,
to
avoid
the
risk
of
discoloration
and/or
deformation.

ARAL

PAL
{ Additional Precautions |
@
Protect
the
unit
from
strong
impact.
@
Do
not
allow
objects
or
liquids
of
any
kind
to
penetrate
the
unit.
In
the
event
of
such
an
occurrence,
discontinue
use
immediately.
Contact
qualified
service
personnel
as
soon
as
possible.
@
Should
a
malfunction
occur
(or
if
you
suspect
there
is
a
problem)
discontinue
use
immediately.
Contact
qualified
service
personnel
as
soon
as
possible.
[About the Supplied Microphone |
@
Before
using
the
supplied
microphone
you
need
to
install
a
battery.
(Dry
battery:R03(AAA)type)
@
The
microphone
is
provided
with
its
own
power
switch
(turns
current
from
battery
on
and
off).
Always
make
sure
to
slide
it
to
the
“OFF”
position
when
the
microphone
is
not
being
used.
Roland
ON
Power
ON
OFF Power OFF
@
On
average,
the
battery
should
last
for
about
5,000
hours.
However,
anytime
you
notice
that
the
microphone
has
decreased
in
sensitivity,
or
that
the
sounds
picked
up
are
not
converted
to
MIDI
correctly,
replace
the
battery
with
a
new
one.
@
If
you
do
not
intend
to
use
the
microphone
for
an
extended
period
of
time,
remove
the
battery
as
a
precaution
against
leakage
and
possible
damage.

@How to Replace the Battery}
@) Remove off the windscreen covering the tip of the microphone.
Zé:

@ Screw off the microphone’s cap by turning it counterclockwise.
B
@ Remove the battery, and while carefully observing the polarity (“}” versus “—"}, replace it with a
new one.
@
O
Dry Battery
@ Once the new battery is in place, reverse steps (7) and (2) to screw on the cap and replace the
windscreen.

one of your own) or the patch cord from an electric instrument (guitar, etc.) to this
jack.
. © Parameter Indicators
These LEDs indicate the parameters selected in the Edit mode. They also indicate
the degree to which the input signal has drifted from a known reference pitch.
_-@ Display
The Display indicates the current mode status, the note name of the pitch being
input, the MIDI parameter settings.
_ @ Select Button
| This button allows selection of the parameters that are set in the Edit mode.

2. GETTING STARTED
(1) MIDI Data Transmitted by the CP-40
The types of MIDI data capable of being transmitted by the CP-40 are explained in the following.
@ MIDI Data Output As a Representation of Source Signals Being Input
Audio signals entering the CP-40 are converted, then output as the following types of MIDI data:
#Note Messages: Note On, Note Off, Velocity
¢ Control Change Messages: Expression (Control No. 11)
* Pitch Bend Messages
* When Velocity/Expression (VELO/EXP) is set at E1/E2, EXPRESSION messages will be generated in a form
reflecting the amplitude of the sound. However, when VELO/EXP is set at V1/V2, no EXPRESSION messages
will be generated. Instead, the sound’s amplitude will be output in terms of VELOCITY. (see page 17, “Velocity/
Expression”)
@ Control Slider
By moving the Control Slider, the following MIDI data is transmitted:
Control Change Messages: General-Purpose Controller No. 1 (Control No. 16).
© About the MIDI Implementation Chart
MIDI is able to transmit and receive data between various types of devices, but not all devices are able to transmit and
receive the same types of data. The owner's manual of each MIDI device has a “MID! Implementation Chart” which
shows the types of data that the device is able to transmit and receive. (see page 23.)
All Implementation Charts are a standard size, so that you can place two charts side by side to see how two devices
will be able to communicate with each other.
