on in any other order could cause a malfunction or damage. When turning the power off, turn off the
connected system first and then the .
▫The unit has a protection citcuit that causes a short delay between powering the unit on, and normal
operation of the unit.
▫Lower the volume before turning the unit on or off. Even with the volume turned down, you may hear
sound when switching the unit on/off. This is normal and does not indicate a malfunction.
Allows you to connect the unit to an external power source or computer via a USB 2.0 (A-microB) cable.
Use a commercially available USB 2.0 cable (A-microB) to connect this port to your computer. It can be used to
transfer MIDI and audio data over USB. The USB driver needs to be installed when connecting the to your
computer, and can be downloaded from the Roland website. For details, refer to the Readme.htm file included
in the download from http://www.roland.com/support/.

Plug in your external MIDI device (controller or keyboard) using a standard MIDI cable to control the .
Standard Kensington lock to secure the unit from theft.
Allows selection of sound patches and banks, along with programming the step sequencer and selecting other
general effects.
The Default mode is when the unit is not in step sequencer mode.
Note: In the below selections if you see MANUAL + [3] [1], [2] for example, this means press the MANUAL
button at the same time as pressing the [3] button, and then let go and press either button [1] or [2].
BANK/PATCH NUMBER [1] –[8]
Loading a Stored patch
You can recall up to 64 stored patches using a combination of bank and patch numbers. There are a total of 8
banks, selectable using BANK numbers 1 to 8, and each bank has a total of 8 patches, selectable using PATCH
numbers 1 to 8. For example pressing BANK [1] followed by PATCH [3] will recall patch number 13 (patch 3 of
bank 1) into the unit’s memory. Likewise selecting BANK [7] followed by PATCH [6] will recall patch number 76
(patch 6 in bank 7). This totals 64 patches comprising numbers 11 thru 88.

Saving the Current patch
You can save up to 64 patches using the bank and patch numbers. An edited patch is indicated by a dot in the
BANK PATCH display. To permanently save an edited patch, press and release one of the BANK buttons [1] to [8],
and then press and hold down (long-press) a PATCH button [1] to [8] until the dot on the BANK PATCH display
disappears - This indicates that the patch has been saved. For example to save the current patch to slot 27,
press and release BANK [2] and then press and hold PATCH [7] until the dot in the BANK PATCH display
disappears, confirming the save is complete. There are 64 slots available to save custom patches 11 thru 88.
Note that saving a patch will overwrite the contents of the original.
CHORUS 1 / CHORUS 2
The has two chorus effects that can be selected by pressing the CHORUS 1 or CHORUS 2 button. When the
button is lit, the chorus effect is on. You can also press both CHORUS 1 and 2 for an additional chorus effect.
MANUAL
Pressing the MANUAL button will copy the physical settings of the buttons, knobs, sliders, and switches, to the
current patch. This allows the physical settings to be copied to the virtual memory so they are in sync and the
sound of the patch represents the physical settings of the buttons.
CHORUS 2 + [14]
Enters solo mode where playback is monophonic. Ie. Only a single note can sound at any given time.
CHORUS 2 + [15]
Enters unison mode where all sounds are played in unison. Ie. All 4 notes of polyphony are played with one key
press.
CHORUS 2 + [16]
Enters Polyphonic mode where up to 4 notes of polyphony can be played. Playing more than 4 notes results in
“note stealing”, where each successive note above 4-note polyphony cuts off prior notes to maintain the 4-note
maximum.
CHORUS 2 + [4] thru [13]
Shifts the keyboard range in steps of one octave from button [4] (-4) thru button [13] (+5). The default of ±0 is
[8].
CHORUS 2 + C1
Switches portamento on and off to create a smooth change in pitch between notes played.
CHORUS 2 + C2
Adjusts the portamento time for the pitch change from 1 (slow) to 100 (fast). This affects how quickly the pitch
changes between note plays.
MANUAL + [1] [1] thru [16]
Specifies the master tuning from [1] (433Hz) to [16] (448Hz). The default of 440Hz is [8].
MANUAL + [2] [1] thru [16]
Specifies the MIDI receive/transmit channel 1 thru 16.
MANUAL + [3] [1], [2]
Specifies the MIDI Clock source.

5
[1] AUTO (default). This will synchronize the ’s tempo to the external MIDI clock signal coming from
the MIDI IN connector.
[2] INTERNAL. This will cause the to operate at the tempo of the unit itself.
MANUAL + [4] [2] thru [13]
Transpose the keyboard range up or down in semitones, where the default of ±0 is [8]. This only applies when
using the K-25m keyboard.
MANUAL + [5] [1] thru [3]
Adjusts the key velocity value that will be transmitted when playing the keyboard. This only applies when using
the K-25m keyboard.
[1] TOUCH. Transmits the actual keyboard velocity.
[2] (64). Transmits a fixed velocity of 64 (half) regardless of the actual velocity.
[3] (127). Transmits a fixed velocity of 127 (max) regardless of the actual velocity.
MANUAL + [6] [1] thru [3]
Sets the velocity curve of the keyboard. This only applies when using the K-25m keyboard.
[1] LIGHT. Sets the keyboard to a light touch.
[2] MEDIUM. Sets the keyboard to the standard touch.
[3] HEAVY. Sets the keyboard to a heavy touch.
MANUAL + [7] [1], [2]
Sets Auto Off.
[1] OFF. Prevents the unit from powering down automatically.
[2] 30 min. Causes the unit to turn off automatically after 30 minutes of inactivity. Auto Off will not occur
while the unit is plugged in via USB.
MANUAL + [8] [1] thru [4]
Specifies the length of inactivity before the LED demo turns on.
[1] OFF. Prevents the unit from entering the LED demo.
[2] 1 min. Causes the LED demo to engage after 1 minute.
[3] 3 min. Causes the LED demo to engage after 3 minutes.
[4] 10 min. Causes the LED demo to engage after 10 minutes.
MANUAL + [9] [1], [2]
Sets Chain Mode on or off. Chain Mode can be used to increase polyphony by connecting more units via
MIDI cable.
[1] OFF. Prevents communication with additional units.
[2] ON. Allows additional polyphony with more units attached via MIDI cable. In this mode, the 5th
and subsequent notes are passed through to additional units via MIDI out.
MANUAL + [10] [1] thru [16]
Sets the ribbon controller note scale. The default is [1].
MANUAL + [11] [1], [2]
Sets the modulation hold of the C2 ribbon controler.
[1] HOLD OFF (default)
This is like having a spring on the mod-wheel –the second you take your finger off it, the modulation effect
jumps back down to zero.

6
[2] HOLD ON
This forces the mod wheel to remain at the point you take your finger off it, which is like a standard mod-
wheel without a spring.
MANUAL + [12] [1] thru [3]
Allows you to adjust the chorus noise, as simulated from the original Juno 106.
[1] NOISE OFF. Turns off the simulated chorus noise.
[2] HALF. Turns on the simulated chorus noise but sets it to half-volume.
[3] ORIGINAL JUNO CHORUS. This is the default Juno 106 chorus with noise.

Specifies the Pitch Bend range in semitones.
[1] thru [12] 1 thru 12 semitones, with a default of [2]
[13] 2 Octaves
[16] OFF
MANUAL + [14] [1] thru [16]
Adjusts the delay level applied to the patch. [1] is no delay, and [2] thru [16] adjust it incrementally for a more
pronounced effect.
MANUAL + [15] [1] thru [16]
Adjusts the delay time applied to the patch in incremental adjustments of [1] thru [16]. Note that this delay time
refers to the length of time before the delay takes effect, not how long the delay effect is.
MANUAL + [16] [1] thru [16]
Adjusts the delay feedback applied to the patch. [1] is no feedback, and [2] thru [16] adjust it incrementally for a
longer delay.
The step sequencer lets you input notes in up to 16 steps, and then play the notes back in a repeating loop. The
number of steps can be adjusted from 1 to 16, and a maximum of 16 individual patterns can be stored.
Press both the CHORUS 2 and MANUAL buttons (SEQ) simultaneously to enter or exit step sequencer mode.
Step Buttons [1] thru [16]
In Step Sequencer mode, the BANK and
PATCH NUMBER buttons represent the
16 steps of the sequencer. While in this
mode, the following button press options are available:
MANUAL
Starts and stops playback of the sequence.
CHORUS 2 + C1
Sets the tempo of the playback sequence. Up on the C1 ribbon controller is faster and down is slower.

7
[1] thru [16]
These represent the 16 steps of the sequencer. Press one of the 16 buttons to toggle the step on (lit) or off
(unlit). Lit steps will sound during sequence playback, while unlit steps will not.
[1] thru [16] + C1 (or a note on the keyboard)
Assigns the note to the selected step. Hold down the step button and press a note on the keyboard, or use the
C1 ribbon controller to select a note.
Step Button + Next Step Button (eg. [1] + [2])
Enters a tie between the two step buttons.
[1] thru [16] + C2
Adjusts the gate time of the selected step/note. This is the length of the note, where UP on the C2 ribbon
controller is longer, and DOWN is shorter.
CHORUS 2 + C2
Adjusts the gate time of all steps in the sequence. This is the length of all notes in the sequence, where UP on
the C2 ribbon controller is longer, and DOWN is shorter.
CHORUS 2 + [1] thru [16]
Selects one of the stored sequencer patterns.
CHORUS 2 + [1] thru [16] (long press)
Saves and assigns the current sequencer pattern to the button selected.
MANUAL + [1] [1] thru [16]
Assigns the number of steps in the sequence (min 1, max 16).
MANUAL + [2] [4] thru [12]
Sets the shuffle (default is 8). This plays the notes “out-of-time” or a little offbeat. The higher the number, the
more pronounced the shuffle is.
MANUAL + [3] [1] thru [4]
Sets the scale (default is 2).
MANUAL + [15] [1] thru [7]
Sets the step order, much like an arpeggiator. Choices are:
1 Normal (default)
2 Even/Odd reverse
3 Odd Only
4 Even Only
5 Odd Only Even Only
6 Even Only Odd Only
7 Random
MANUAL + [16] [1] thru [2]
Sets Off Step mode as follows:
1 Rest (Default)
2 Skip

This is a touch-type ribbon controller that emulates a pitch bend wheel, and will preview sound when the
is not connected to a controller. I can also adjust settings in various modes. Sliding up increases the pitch of the
note, while sliding down decreases the pitch.
This is a touch-type ribbon controller that emulates a modulation wheel. It is also used to adjust settings in
various modes. Sliding up increases the modulation effect, while sliding down decreases the effect.
The LFO section can be used to create cyclic changes (modulation) in the sound over time, by applying a Low
Frequency Oscillator (LFO).
RATE Slider
This determines the speed of the LFO, or how fast the cyclic changes take place.
DELAY TIME Slider
This determines how long it takes before the LFO kicks in after playing the sound.
Here you can select the pitch of the sound, as well as the waveform that determines the timbre or “character”
of the sound.
RANGE [16] [8] [4]
This specifies the octave of the digitally controlled oscillator. This simply changes the root octave of the DCO,
with 4 being the highest pitch, and 16 being the lowest.
LFO Slider
This allows the LFO to modulate the pitch of the sound, producing vibrato. Moving the slider up makes the LFO
effect more pronounced while moving it down reduces the effect.
PWM Slider / [LFO/MAN] Switch
The slider modifies the Pulse-Width of the DCO in the following manner, based on the [LFO/MAN] switch
setting:
MAN The PWM Slider adjusts the value of Pulse-Width of the DCO.
LFO The PWM Slider adjusts the depth of the Pulse-Width modulation.
Button
Selects the Sawtooth wave for the DCO
Button
Selects the Square wave for the DCO
SUB Slider
Adjusts the volume of the sub-oscillator, which is a waveform 1 octave below the DCO. The sub-oscillator is like
having a second DCO but with limited functionality, and is great for adding bass to the sound.

NOISE Slider
Adjusts the volume of the noise added to the sound.
HPF is a High-Pass Filter that only allows higher frequencies to pass through to the output.
FREQ Slider
This sets the cutoff frequency of the high-pass filter. Frequency bands below the cutoff are filtered out while
those above are allowed to pass through, removing bass and giving the sound a “thinner” timbre.
VCF is a Low-Pass Filter that only allows lower frequencies to pass through to the output.
FREQ Slider
This sets the cutoff frequency of the low-pass filter. Frequency bands above the cutoff are filtered out while
those below are allowed to pass through, removing higher frequencies and giving the sound a mellower, subtle,
or rounded timbre.
RES Slider
This controls the resonance, which boosts the sound around the filter’s cutoff frequency. Higher resonance
provides more emphasis to the frequencies around the filter cutoff frequency, producing more electronic or
synthesizer textures. To an extent, it also deemphasizes some of the lower frequencies in the sound.
ENVELOPE Switch
This selects the polarity (direction) of the filter envelope.
ENV Slider
Adjusts the depth by which ENV controls the cutoff frequency.
LFO Slider
Adjusts the depth by which LFO modulates the cutoff frequency.
KBD Slider
This allows the cutoff frequency to be adjusted automatically depending on the notes you play. It is needed to
counteract some of the impact that a filter can have on frequencies as you play up and down a keyboard. For
example with a low-pass filter, the sound becomes more muted and less precise as you play higher notes. To
counteract this, moving the KEY FOLLOW slider upward will cause the cutoff frequency to increase as you play
progressively higher notes.
VCA is a Voltage Controlled Amplifier that allows you to adjust the volume of the patch.
LEVEL Slider
This adjusts the amplitude (volume) of the patch.
ENVELOPE Switch
This selects the polarity (direction) of the amplitude envelope.

This allows you to adjust how the amplitude (volume) of the sound changes over time using an ADSR (Attack,
Decay, Sustain, and Release) envelope.
Attack
Attack Time. How quickly the amplitude envelope reaches the maximum value after pressing a key.
Decay
Decay Time. How quickly the amplitude envelope reaches the Sustain Level while a note is held down.
Sustain
Sustain Level. The amplitude level at which the sound will remain while a note is held down.
Release
Release Time. How quickly the envelope reaches minimum amplitude value after the note is released.
Perform the following steps to return your back to the default factory settings:
1. Turn the POWER button [A] to ON while holding down the BANK [1] button.
The MANUAL button should blink, indicating that the unit is ready to be reset. Simply turn the POWER button to
the OFF position if you choose to cancel the reset at this point, otherwise continue with step 2.
2. Press the MANUAL button to perform the factory reset.
3. When all buttons blink, switch the ’s power button to OFF, and then back to ON again.
The unit is now reset back to the default factory settings.
