"Warning -This equipment has been verified to compiy with the limits for aClass Bcomputing device, pursuant to
Subpart J, of Part 15, of FCC rules. Operation with non-certified or non-verified equipment is likely to result in
interference to radio and TV reception."
The equipment described in this manual generates and uses radio-frequency energy. If it is not installed and used
properly, that is, in strict accordance with our instructions, it may cause interference with radio and television recep-
tion.
This equipment has been tested and found to comply with the limits for aClass Bcomputing device in accordance
with the specifications in Subpart J, of Part 15, of FCC Rules. These ruies are designed to provide reasonable protec-
tion against such ainterference in aresidential installation.
However, there is no guarantee that the interference will not occur in aparticular installation. If this equipment
does cause interference to radio or television reception, which can be determined by turning the equipment on and
off, the user is encouraged to try to correct the interference by the following measure:
•Disconnect other devices and their input/output cables one at atime. If the interference stops, it is caused by
either the other device or its I/O cable.
These devices usually require Roland designated shiefded I/O cables. For Roland devices, you can obtain the proper
shielded cable from your dealer. For non Roland devices, contact the manufacturer or dealer for assistance.
if your equipment does cause interference to radio or television reception, you can try to correct the interference by
using one or more of the following measures:
•Turn the TV or radio antenna until the interference stops.
•Move the equipment to one side or the other of the TV or radio.
•Move the equipment farther away from the TV or radio.
•Plug the equipment into an outlet that is on adifferent circuit than the TV or radio. (That Is, make certain the
equipment and the radio or television set are on circuits controlled by different circuit breakers or fuses.}
•Consider installing arooftop television antenna with coaxial cable lead-in between the antenna and TV.
If necessary, you should consult your dealer or an experienced radio/television technician for additional suggestions.
You may find helpful the following booklet prepared by the Federal Communications Commission:
"How to Identify and Resolve Radio—TV interference Problems"

procedure taking care of the following points.
Press the Verify or Load key before the data
you are to verify or load starts.
Please do not start recording from the very
head of the tape, but after slightly winding
it.
Make sure that connections are made prop-
erly.
Tape you use
Use anew and high quality tape, if possi-
ble. An old tape is liable to have drop-out,
therefore likeiy to cause error more often.
Use acassette tape shorter than C-60. The
one longer than C-90 is too thin for proper
operation.
Try using the same tape recorder in Saving
and Loading, so that possibility of error will
be reduced.
If your tape recorder has two kinds of In/
Out Jacks (i.e. MIC/LINE in, EAR/LINE Out,
etc), try using different ones this time.
Some tape recorders do not allow proper
operation when both Save and Load con-
nections are made at the same time. In
such acase, make only the relevant con-
nection.
•Clean and demagnetize the head of the
tape recorder.
*If error is still indicated, use adifferent tape
recorder.
Preserving Data Tape
Please do not keep the data recorded tape
in extreme heat or humidity or near
strongly magnetic units such as speaker or
an amplifier. Also, be sure that the tape is
completely rewinded.

(Digitally Controlled oscillator)
DCO is the digitally controlled oscillator that
controls the pitch and creates two types of
waveforms which are the sound source of the
synthesizer. Compared to VCO (Voltage Con-
trolled Oscillator), DCO has superior stability.
The operations and functions of the DCO are
virtually the same as those of the VCO.

You can select the output waveform of the
DCO. Each switch can be individually turned
on or off and can be simultaneously used with
another switch.
(2) PWM Mode Switch
When it is set to MAN, pulse width can be set
to a certain ratio. When it is set to LFO, pulse
width is controlled by the signal from the LFO.
When PWM Mode switch ©is set to MAN,
this knob controls the pulse width, and con-
trols the intensity of the modulation when it is
set to LFO
(7) Range Selector Button
This selects the pitch of the DCO. When it is
set to 8', "do "(C) 3rd from the lowest falls on
the Middle Cof apiano keyboard. By using 4'
or 16' position, one octave is shifted up or
down, changing total range of the keyboard.
(Refer to P. 24 for the details)
<Pulse Width >
When the top and bottom portions of the
square wave are unequal, the result is what is
called a pulse wave. The harmonic content of
the pulse wave will depend greatly on the
width of the pulses, it is possible to modulate,
or change the pulse width by means of the
LFO.
(J) SUB •Sub Oscillator Level Knob
It controls the volume of the Sub Oscillator.
(5) LFO •Modulation Knob

{High Pass Filter)
This filter lets the high frequency harmonics
pass and cuts off the iow frequency har-
monics. As this fitter is not voltage controlled,
Cutoff Point is changed by only moving the
knob.
©Cutoff Frequency Knob
This knob sets the Cutoff point of the HPF.
With this set to 1, the DCO output passes the
filter unprocessed, and as it is raised, Cutoff
point is heightened, higher harmonics being
passed. In the meantime, at its lowest posi-
tion "0", lower frequencies are boosted.
(This is specially useful for boosting bass
sound of organ, etc.)
(Voltage Controlled Filter)
This filter changes the tone color by cutting off
or emphasizing harmonics. This filter lets the
iow frequency harmonics pass and cuts off
the high frequency ,and is controlled by avol-
tage.

(2) FREQ •Cutoff Frequency Knob
This knob is to change the Cutoff Point of the
VCF. As you lower the knob, higher frequen-
cy will be cut off, and the sound will fade
out when the waveform becomes nearest to
Sine Wave.
(3) RES •Resonance Knob
This control emphasizes the Cutoff Point set
by Cutoff Frequency knob ©. As you raise the
knob, certain harmonics are emphasized and
the created sound will become more unusual,
more electronic In nature. If you alter the
Cutoff Frequency Knob while the Resonance
Knob is set to ahigh level, you can create a
type of sound that is attainable only from a
synthesizer. If you raise the Resonance knob
up to the maximum, the VCF will start its self
oscillation.
<4j
When the Cutoff Point of the VCF is being
modulated by the output of the Envelope
Generator, this knob is used to adjust the in-
tensity of the modulation. You can change the
Cutoff Point of the VCF in each note with the
ADSR pattern previously set. So the tone
color within one note can be changed quite
drastically.
(5) F
This is the selector switch for the polarity of
the Envelope. When it is set at reverse polar-
ity, the ADSR pattern will be reversed and the
tone color alteration will be the other way
round.

®LFO •LFO Modulation Knob
When the Cutoff Point of the VCF is being
modulated by the output CV of the LFO, this
knob adjusts the depth of the grow! or wah ef-
fect.
®KYBD •Key Follow Knob
When the Cutoff Point is being controlled by
the KYBD-CV {Keyboard control voltage), this
knob adjusts the level of the KYBD-CV. It pre-
vents any inconsistency in the harmonic con-
tent caused by pitch alteration. Consequently
this knob is usually set to the maximum on
such along keyboard, but can be set to your
taste.
The self-oscillation of the VCF does not
guarantee an accurate pitch. Therefore, you
cannot expect acorrect scale when playing
the keyboard.
If using the VCF self-oscillation as a sound
source, its pitch may turn out unstable,
since the Cutoff frequency does not change
continuously. In such acase, change the
position of the FREQ Knob (2) unitit you get
astable pitch. (If you write it into memory
once and recall it, the pitch will be stable)
The factory preprogrammed patches A-31
