Editorial notes added and some of my usual
typos corrected for rev B$

The JU-06A is a sound module that can be used
in conjunction with the K-25m keyboard unit (sold
separately). The sound can be heard through the
built-in speakers. !
The JU-06A can operate on batteries or on USB
bus power. If you are using batteries, insert four
AA batteries, making sure that the batteries are
oriented correctly. %
When turning the unit over, be careful so as to
protect the buttons and knobs from damage.
Also, handle the unit carefully; do not drop it. %
When the batteries run low, the display indicates
“bLo.” Please install fresh batteries. %
Using the JU-06A in conjunction with the DK-01
Boutique Dock (sold separately) %
For installation / removal / angle adjustment, refer
to the DK-01’s Owner’s Manual. %
Using the JU-06A with the K-25m keyboard unit
(sold separately) %
For installation / removal / angle adjustment,,
refer to the K-25m’s Owner’s Manual. %
Playing the JU-06A via MIDI or USB %
You can also play the JU-06A via MIDI or USB.

CONTROLLER ## EXPLANATION!
[HOLD] button # # If you press this button to make it light, the sound of the key !
###you played most recently continues to be heard even after !
###you release your hand. If you play a different key while hold !
###is applied, the sound also changes.!
[CHORD] button #Turns chord memory on. !
[NOTE] button # # If you press this button to make it light, the 10 step buttons !
###can be used as a keyboard. For details, refer to “Using the !
###Buttons as a Keyboard (NOTE)”. !

3LFO!
Here you can create cyclic change (modulation) in the sound. !
CONTROLLER ## EXPLANATION!
[RATE] slider # # Specifies the LFO’s modulation speed.!
[DELAY TIME] slider #Specifies the time from when the tone sounds until the LFO !
###reaches its maximum amplitude. !
4 DCO%
Here you can select the waveform that determines the character of the sound, and specify its pitch. !
CONTROLLER ## EXPLANATION!

buttons!
[LFO] slider # # Allows the 3LFO to modulate the pitch, producing a vibrato !
###effect !
[PWM] slider # # When the [LFO/MAN/ENV] switch is “MAN” (MANUAL) !
###Adjusts the value of the pulse width. !
###!
###When the [LFO/MAN/ENV] switch is “LFO” !
###Adjusts the depth of modulation produced by the LFO. !
###!
###When the [LFO/MAN/ENV] switch is “ENV” !
###Adjusts the depth of modulation produced by the ENV. !
###WHAT IS PULSE WIDTH?!
###Pulse width is the amount of the upper portion of the pulse wave, expressed as #!
###a percentage of the overall wavelength. !
###!
###If the upper and lower widths are not the same, the waveform is called an !
###asymmetric pulse wave.%
[LFO/MAN/ENV] switch #Selects whether the pulse width value is the fixed value !
###specified by the [PWM] slider (MAN), is modulated by the 3!
###LFO (LFO), or is modulated by the 8ENV (envelope). !
[SQUARE/PULSE] #Selects the waveform that is the basis of the sound.!

Button###(Square wave/Asymmetrical pulse wave).!

5HPF%
This is a high-pass filter that passes the high frequencies and cuts the low frequencies. !
CONTROLLER ## EXPLANATION!
[FREQ] slider # # Specifies the cutofffrequency of the high-pass filter. # # # #
###Frequency components below the cutofffrequency are cut. !
6VCF%
This is a low-pass filter that passes the low frequencies and cuts the high frequencies. !
CONTROLLER ## EXPLANATION!
[FREQ] slider # # Specifies the cutofffrequency of the low-pass filter. # # # #
###Frequency components above the cutofffrequency are cut, !
###making the sound mellower.%
[RES] slider # # Resonance boosts the sound in the region of the filter's cutofffrequency.%
###Higher settings produce stronger emphasis, creating a distinctively “synthesizer- !
###like” sound. !
[POLARITY] switch #Selects the polarity (direction) of the envelope.!
[ENV] slider # # Adjusts the depth by which the 8ENV (envelope) controls the cutofffrequency. !
[LFO] slider # # Uses the 3LFO to vary the cutofffrequency.!
[KYBD] slider # # Adjusts the way in which the pitch of the note affects the cutofffrequency (key !
###follow) when using the keyboard to control cutofffrequency. If this slider is !
###moved upward, the cutofffrequency rises as you play higher notes. !

Here you can adjust the amount of time-varying change (envelope) for the volume. !
CONTROLLER ## EXPLANATION!
[ENV/GATE ] switch #Selects whether the volume is controlled by 8ENV (envelope) or by the gate #!
###signal.%
