Operation Manual

The Roland Juno-6 is asix voice and
sixty-one key polyplionic synthesizer.
•The Digitally controlled Oscillator that
offers exceptionally stable pitch.
•The real six voice polyphonic synthesizer
connpletely equipped with 6VCF's,
6VGA's and 6ENVs.
•An Arpeggio function that enables you to
enjoy wide variation of the patterns by
changing the MODE and the RANGE.
•Chorus effects that expand the sounds for
arich performance.
•Akey transpose function that allows you
to transpose to any keys.
•It is necessary for you to understand the
functions of the controls and selectors
of the Juno-6 perfectly so that you can
fully enjoy the advantages of the unit.
Some setting examples are shown in this
manual so that it might be easier for you
to master how to operate the Juno-6,
but you are the one who creates the
sounds. Please find out your own setting
and new ways of playing.

I. Functions for Sound Creating
DCO
(Digitally Controlled Oscillator)
DCO is the digitally controlled oscillator that
controls the pitch and creates three types of
waveforms which are the sound source of
the synthesizer. Compared to VCO (Voltage
Controlled Oscillator), DCO has superior
stability. The operations and functions of
the DCO are virtually the same as those of the
VCO. ADCO does not, however, provide
portament function, because of its digitally
controlled system.

You can select the output Waveform of
the DCO. Each switch can be individually
turned on and off and can be used with
other switches.
(2) PWM MODE switch
When it is set to (MAN), pulse width can be
set with the PWM knob (3). When it is set to
LFO or ENV, pulse width is controlled by
the corresponding signal from the LFO or the
envelope generator.
(3) PWM ePulse Width Modulation
When PWM MODE switch (2) is set to (MAN),
this knob controls pulse width, and controls
the intensity of the modulation when it is set
to LFO or ENV.
SUB OSC •Sub Oscillator Level
It controls the volume of the SUB OSC.
(5) LFO •LFO MODULATION
It adjusts the depth of the vibrato effect
when the LFO is controlling the pitch of the
DCO.
(6) NOISE eNOISE level
It controls the volume of the NOISE.
<Pulse Wave>
When the top and bottom portions of the
square wave are unequal, the result is what is
called apulse 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 or the envelope generator.

Description
The sawtooth wave contains
afundamental sine wave and
its integral harmonic sine
waves at afixed ratio. The
level of each harmonic is as
shown on the right. When
fundamental content is 1,
the content of «th harmonic
is 1/n.
The square wave contains a
fundamental sine wave and
its odd numbered harmonics
at afixed ratio. The level of
each harmonic is the same as
sawtooth wave; the content
of nth harmonic is 1/«;
except that there are no even
numbered harmonics.
With pulse wave, the har-
monic content greatly varies
depending on the pulse
width. It is characterized by
alack of the nth harmonic
series when the pulse width
is 1/«. The example on the
left lacks 3rd, 6th, and 9th
harmonics because the pulse
width is 1/3 (33%).

HPF
(High Pass Filter)
This filter lets the high frequency harmonics
pass and cuts off the low frequency harmo-
nics. As this filter is not voltage controlled.
Cutoff Point is changed by only moving the
knob.
FREQ •Cutoff Frequency
Cutoff Point of HPF can be adjusted with
this knob. As you raise this knob, frequencies
in the low pitch range will be cut off.
VCF
(Voltage Controlled Filter)
This filter changes the tone color by cutting
off or emphasizing harmonics. This filter lets
the low frequency harmonics pass and cuts off
the high frequency harmonics, and is con-
trolled by avoltage.
@FREQ •Cutoff Frequency
This knob is to change the Cutoff Point of the
VCF. As you lower the knob, the frequency
in the high pitch range will be cut off, and the
sound will fade out when the waveform be-
comes nearest to aSine Wave.
^C^^ •> Refer to P. 15
(^ RES •Resonance
This control emphasizes the Cutoff Point set
by Cutoff FREQUENCY knob @. As you
raise the knob, certain harmonics are em-
phasized and the created sound will become
more unusual more electronic in nature. If
you alter the Cutoff FREQUENCY knob
while the RESONANCE is set to ahigh level,
you can create atype of sound that is attain-
able only from asynthesizer. If you raise
the RESONANCE up to the maximum, VCF
will start Self Oscillation.
(5) ENV •Envelope Modulation
When the Cutoff Point of the VCF is being
modulated by the output of the Envelope
Generator, this knob is used to adjust the
intensity 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 of one note can be changed quite
drastically.
(D Polarity Switch
This is the selector switch for the polarity
of the Envelope. When it is set at reverse
polarity, the ADSR pattern will be reversed
and the tone color alteration will be the other
way round.
*NOTE
This often means the Cutoff Frequency of
the VCF (HPF) will need to be set higher.
(6) LFO •LFO Modulation
When the Cutoff Point of the VCF is being
modulated by the output CV of the LFO,
this knob adjusts the depth of the growl or
wah effects.
(D KYBD •Key follow
When the Cutoff Point is being controlled
by the KYBD-CV (Keyboard control voltage),
this knob adjusts the level of the KYBD-CV.
It prevents any inconsistency in the harmonic
content caused by pitch alteration. Conse-
quently this knob is usually set to the maxi-
mum on such along keyboard, but can be set
to your taste.
*NOTE
Self oscillation of the VCF does not guarantee
accurate pitch. So, you cannot obtain correct
scale when playing the Keyboard.

NOTE
When modulating the VCF using the Enve-

case of positive porality, and set it to afairly
high level in case of negative. Otherv\/ise there
will be little effect.

VGA
(Voltage Controlled Amplifier)
This is to control the volume (amplitude) of
the sound, and is normally controlled by the
output voltage from the Envelope Generator.
(?) Select switch for the control signal
This switch enables you to select whether to
control the VGA by the signal from the
Envelope Generator or by the Gate signal.
ENV
(Envelope Generator)
This generates the Control Voltage applied to
the VCF and the VGA, thereby controlling
the volume and the tone color of each note.
This output voltage is generated whenever you
press akey.
®
@A{Attack time)
This sets the time required for the voltage
to reach its maximum from the moment the
key is pressed down.
(3) D(Decay time)
This determines the time required for the
voltage to drop from the maximum to the
sustain level. When the sustain level is high,
the Envelope curve does not change by
adjusting the Decay Time.
S(Sustain level)
This knob determines the Sustain Level to
which the voltage falls at the end of the Decay
Time.
(5) R(Release time)
This sets the time needed for the voltage to
reach zero.

*In the figure shown above, the positions of

so the knob position does not necessarily cor-
respond with the time and the voltage.
** When all of the ADSR sliders are set at
"0", the waveform will be an extremely
short Pulse wave, and only ashort "click"
is heard. Please be careful.
LFO

This oscillator operates only at aLow Fre-
quency. It controls the VCO and the VCF to
produce vibrato and growl effects.

on the position of the TRIGGER MODE
switch (2).

The LFO does not start to
function until the Delay Time
set with the DELAY TIME
has passed. (*)
While the TRIGGER button
is being pressed, the LFO
amplitude becomes larger.
When the delay time set pre-
viously has passed, it becomes
normal amplitude.
This Delay function works only in non-
legato manner. So the Delay Time affects
only the first key in alegato section.
