LFO section
Adds cyclical change (a swelling effect) to the sound.
Controller
(Parameter) Value Explanation
[RATE] knob 0–10 Sets the speed of the LFO cycle.
[DELAY TIME] knob
0–10 Sets the time it takes before the LFO effect begins after you
press a key.
The larger the value, the longer it takes for the LFO effect to
start after you play the keyboard.
[WAVEFORM]
switch
Đ
(sine wave), (square
wave), RND (random)
Selects the LFO waveform.

Panel Descriptions
6
DCO-1/DCO-2 Section
This section is used to select the waveforms that determine the character of the sound, and to set the pitch.
Controller
(Parameter)
Value Explanation
[LFO] slider
0–10
Sets how much LFO modulation is applied to DCO-1 and DCO-2.
[TUNE] knob
-1OCT–+1OCT
Shifts the pitch in units of a semitone.
[FINE TUNE] knob
-–+
Finely adjusts the pitch.
[RANGE] switch

[WAVEFORM] knob
This knob sets the waveform.
Sawtooth wave
Pulse wave
ē
Square wave
Noise
[CROSS MOD]
switch
This selects the mode in which the modulation operates.
X-MOD
The DCO-1 and DCO-2 interact to generate the pitch, harmonic components and
output waveform.
SYNC
Synchronizes the oscillators. This creates a complex waveform by forcibly restarting
DCO-2 so that it syncs with the cycle of DCO-1.
OFF
DCO-1 and DCO-2 each generate their own pitches and waveforms.
[DCO-1 ENV] knob
[DCO-2 ENV] knob
0–10
Adjusts how much the envelope selected with the MODE switch is used to
modulate DCO-1 and DCO-2.
[MODE] switch

VCF Section
This section controls the filter to alter the sound of the tone.
Controller
(Parameter)
Value Explanation
[HPF] slider
0–3
Specifies the cutoff frequency of the high-pass filter.

Increasing the value emphasizes the frequencies around the cutoff frequency for a
more unusual sound.
Excessively high settings can produce oscillation, causing the sound to distort.
[LFO] slider
0–10
Sets how much LFO modulation is applied to the cutoff frequency.
[KEY FOLLOW]
slider
0–10
Changes the cutoff frequency according to the keys you play.
With a larger value, playing notes above C4 (middle C) on the keyboard increases the
cutoff frequency the higher you go.
[ENV] knob

Sets how much effect that the envelope you selected using the [MODE] switch has on
the cutoff frequency.
[MODE] switch
1
(NORMAL),
1 (INVERSE),
2
(NORMAL),

[RELEASE] slider
0–10
Sets the release time.
[KEY FOLLOW]
switch
0–3
Changes the envelope time (ATTACK, DECAY, RELEASE) according to the key you play.
Playing notes higher than C4 (middle C) shortens the envelope time as you go up, and
playing notes in the lower range lengthens the envelope time as you go down.
Larger values produce greater change.

Turning the Power On
15
Turning the Power On
Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some
sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
1. To turn on the power, slide the [POWER] switch to “ON.”
When you operate the sound module such as for adjusting the angle or mounting the unit, be careful not to get your fingers
pinched between the movable parts and this unit. In places where small children are present, make sure that an adult provides
supervision and guidance.
Do not use a USB cable that is designed only for charging a device. Charge-only cables cannot transmit data.

Selecting a Tone (Patch)
16
Selecting a Tone (Patch)
The settings for each tone are stored in a block of memory called a “patch.” By selecting (switching between) patches, you can use
a variety of sounds.
The patches are further organized by group (A–D), bank (1–8) and number (1–8), letting you save a total of 4 x 8 x 8 = 256 patches.
1. Press the NUMBER [1]–[8] buttons.
This selects the patch.
●
You can use the [VALUE] knob to select from all of the patches in order.
●You can select separate patches for parts A and B. For details on the part settings, refer to “3.2. Switching Between
Parts(P.18).”
Selecting Groups and Banks
Here’s how to switch the group and bank for the patches.
1. Press the BANK [1 (5)]–[4 (8)] buttons.
This selects the bank. The bank (1Ð5, 2Ð6, 3Ð7, 4Ð8) and group (A–D) switches each time you press the same bank
button.

This switches between parts.
●
If you switch patches here, you can change the tone of this part.
●By holding down the [NOTE] button and pressing the PART [A] or [B] button, the unit switches to that part, regardless of
the current mode.

Using the Keyboard Split to Play Different Parts (SPLIT Mode)
In SPLIT mode, the keyboard is divided into two zones, and either PART A or PART B plays depending on which zone you play in.
All notes you play in the lower zone of the keyboard at or below the position on the keyboard that divides the zones (called the
“split point”) play PART A, and all notes played in the higher zone play PART B.
1. Press the [SPLIT] button to make the indicator light.
SPLIT mode turns on.
Changing the position that divides the zones (split point)
You can change the split point on this unit.
1. Press the [MENU] button.
The MENU screen appears.
2. Use the [VALUE] knob to select “KEY,” and press the [VALUE] knob.
The KEY setting screen appears (11.2. Keyboard Settings(P.40)).
3. Use the [VALUE] knob to select “SPLt,” and press the [VALUE] knob.
4. Use the [VALUE] knob to select the split point (key).
When a K-25m is connected, you can hold down the [SPLIT] button and press a key to set the split point.
5. To exit the settings, press the [MENU] button.
