General /Names and functions
General
The DecaBuddy mixes up to 9 voice sound in addition, to the original 1 voice sound. That’s where the name
deca (Deca=10) comes from.
From the monaural vocal signal input, up to 4 harmony voices are generated and the unison voices for the
original voice and 4 harmony voices can be generated. The harmonies can, of course, be layered using the
preset programs and the programs can be edited to create the harmony customized to the song you play.
You can also layer the harmonies using the MIDI signal or play it via MIDI.

sound mixed with the harmonies.
6. Set the signal output level using the OUTPUT LEVELcontrol.Adjust the signal level appropriately on
the amplifier/mixer.
7. Select the BANK using the BANK/DATA control and switch the PROGRAM with the PROGRAM A/B
buttons.
BANK and PROGRAM
The DecaBuddy has 50 banks. Each bank contains two programs, i.e. PROGRAM A and PROGRAM
B. There are 100 programs in total.All programs can be edited and they can be overwritten as your
original programs.
Practical Operation
Using Preset Programs
Switchthe bank using theBANK/DATAcontroland select the programwith the PROGRAMA/PROGRAM
B buttons.
Try switching the preset programs while singing.
Some programs produce the original vocal sound mixed with the harmony sound, while the other pro-
grams produce only the original vocal sound.
This is because of the difference in MODE, one of the parameters that make up the program.The mode,
suchas STYLE,MODAL, etc., isshown atthe lower rightside ofthe screenwhenthe programis switched.
What is MODE?
The mode decides the way the harmony is generated. The DecaBuddy has 7 modes. Some generate
harmonies to the original vocal sound by itself, while the others generate harmonies based on the MIDI
signal received.
The following is the brief explanation of each mode and its characteristics (refer to EDIT Mode for their
operation).

6
Practical Operation
STYLE: Generates harmony by itself
Theharmony is decidedbysetting the KEYand assigning theharmonypattern (STYLE), suchas Unison,
Octave, 3rd, 5th, etc., to each harmony part. The STYLE has the Preset Styles and, in addition, the User
Styles. The STYLE can be edited and saved.
This makes it easy to set the harmony using with 1 or 2 harmony voices.
CHORD: Generates harmony by itself
The harmony is decided by setting the KEY and by selecting one preset CHORD out of 50 harmony
patterns (CHORD). It is similar to STYLE but not necessary to assign the harmony patterns to each
harmony part. Selecting just one CHORD sets the harmony of all harmony parts. The CHORD can be
edited to create more complex harmonies and the edited CHORD can be saved.
MODAL: Generates harmony based on MIDI note information received
The harmony is generated by setting the KEY, TEMPLATE (specifies the interval, unison, 3rd, 5th, etc.)
and VOICING (specifies the harmony pattern) and receiving the root note of the harmony via MIDI from
the external MIDI keyboard. The appropriate harmonies can be made by specifying just one root note
from the external MIDI keyboard for the songs of a simple chord progression to the very complex one.
FLEXICHORD: Generates harmony based on MIDI note information received
The harmony appropriate to the input sound is generated automatically based on the MIDI note informa-
tion of 3 or more notes received from the external MIDI keyboard or Sequencer. The appropriate harmo-
nies can easily be made by just playing the chord on the keyboard.
MONO CHN.: Generates harmony based on MIDI note information received
The harmony is generated by receiving the MIDI note information of each harmony on separate MIDI
channels.
This mode is useful when using the external sequencer where the harmony data are recorded on the
separate tracks on separate MIDI channels for each harmony. By using the sequence data, each har-
mony can be controlled individually.
WAITALL: Generates harmony based on MIDI note information received
The harmony is generated based on the MIDI note information of one to four notes received from the
externalMIDI keyboard.The harmonyis generated whenthe MIDInoteinformation ofdesignatednumber
of notes is received. As this allows the player to decide which part to play which harmony, the sophisti-
cated harmonies can be assigned in real time, but it always requires the entry of designated number of
MIDI note chords.
PRIORITY: Generates harmony based on MIDI note information received
The harmony is generated based on the MIDI note information of one to four notes received from the
external MIDI keyboard. Not like in WAITALL mode, it is easier to use as the harmony can be generated
with only one MIDI note received, but the harmony part changes depending on the order of MIDI notes
played for the chord.

7
EDIT Mode
EDIT Mode
As available in the Preset Programs, when the programs that generate the harmony by itself, i.e. STYLE or
CHORD, are used, the harmony is obtained just signing into the microphone. However, using the Preset
Program may not produce the optimum harmony for all songs. In order to obtain the optimum harmony for
the song you play, it may be necessary to make the settings accordingly.
Basic Operation in EDIT Mode
While in PLAY mode, after selecting the program to edit, press the EDIT button to enter the EDIT mode.
•Select the parameter to edit using the BANK/DATAcontrol.
•Press the < / > button to move the cursor down to the lower line of the screen and then change the
parameter value using the BANK/DATA control.
•To change other parameter values, press EDIT button to move the cursor up to the upper line of the
screen and then select the parameter to edit using the BANK/DATA control.
By repeating the above procedure, all parameters can be edited.
✽To return to the PLAY mode from EDIT mode, press the EDIT button while the cursor is at upper
line of the screen.
Parameters
The EDIT mode in DecaBuddy is separated in 3 categories, i.e. Harmony parameters, Voice parameters
and Global parameters.
Harmony Parameters:
Sets the formation of the harmony.
Voice Parameters:
Sets the harmony Level, Pan, Formant, etc.
Global Parameters:
Sets the MIDI channel, tuning of the DecaBuddy.
Here, we describe the functions and operations on these 3 categories.
Harmony parameters
They include 7 modes, i.e. STYLE, CHORD, MODAL, FLEXICHORD, MONO CHN., WAITALL and
PRIORITY, and their associated parameters. Depending on the selected mode, the way harmony gener-
ated and their parameters differ.
STYLE
<On STYLE>
The STYLE is the harmony style/pattern generated according to the melody of input signal. The
DecaBuddy has 16 harmony styles, e.g. Unison, Octave, 3rd, 5th, etc., that can be selected accord-
ingly for the song.Also, there are 9 User Styles that can be edited freely to create your own harmony
in STYLE EDIT function.
(Preset Styles)
UN, 8v, 3A, 3B, 3C, 3D, 3E, 3F, 3G, 3H, 5A, 5B, 5C, 5D, 5E, 5F, 5G and 5H
(User Styles)
U1, U2, U3, U4, U5, U6, U7, U8 and U9
Refer to the list of Preset Styles for the details of each Preset.

8
EDIT Mode
<On KEY>
It is not possible to obtain the correct harmony when the KEY setting of the program and that of the
actual song are different. Set the appropriate KEY according to the song.
<To obtain the optimum harmonies>
The program in DecaBuddy using the STYLE generates the harmonies automatically according to
the melody of the input signal. However, it is important to set the appropriate KEY and STYLE in
order to obtain the correct harmony.
TheSTYLE automatically adjusts the intervalof the harmony accordingto the note of theinput, not
just adding the harmony of fixed interval to the melody input. For example, if the style 3E is set for
the song in C major, it generates E (major 3rd) note for the C note input but generates F (minor
3rd) note for the D note input.
In this way, by adjusting the interval of harmony depending on the input note, it can generate the
harmony more musically. To obtain the musical harmony, it is inevitable to set the KEY and select
the STYLE appropriately matched to the song.
<On Modulation>
When there is a modulation in the middle of the song, a single setting of KEY/STYLE may not be
enough to cover the entire song. In such a case, you may need to pre-arrange the User Styles
and/or Programs customized for the song and switch them in the middle of the song. Also, using
the Sub Parameter (refer to Sub Parameters), the Key and/or Style could be switched temporarily.
The Programs can be switched using the footswitch and/or via the MIDI Program Change from the
external MIDI devices.
STYLE mode parameters
KEY:
Sets the KEY for the song.
VOICING:

5. Press the > button to move the cursor to [H1].
6. Turn the BANK/DATA control to change it from [8v] to [3E].
Here, let’s sing into the microphone again. You can hear the different harmonies from the one you
heard before editing. Up to this point, the four harmonies of 1 Octave Down x2, higher 3rd and 1
Octave Up are available.
Next, let’s check how this harmony is constructed.
The STYLE EDIT screen shows the contents of the STYLE assigned. Let’s see the contents of the
STYLE 3E as an example.
7. Confirming that the cursor is at [3E] for H1, press the EXECUTE/STYLE EDIT button. Pressing
the button changes it to show the STYLE EDIT screen indicating [c, c, C, E, C’] on the lower line
of the screen.
✽The lower case alphabet means the lower harmony to the original voice. The [‘] mark beside
the alphabet means the harmony of 1 Octave Up.
8. When the Original voice (ORIGIN) is at [C], the H1 (STYLE 3E) is set to [E]. This means that
when the input is at C note, the harmony of E note will be added.
9. Try turning the BANK/DATA control. When the Original voice (ORIGIN) is at [E], the H1 (STYLE
3E) becomes [G]. This means that when the E note is available at the input, the harmony of G
note will be added.
10. In STYLE EDIT screen, pressing the EDIT button moves the cursor up to the upper line of the
screen and pressing it again returns to the VOICING parameter screen.
✽To save the edited program, refer to Saving/Copying the Program.
✽It is also possible to see the settings using the MIDI note information sent from the external MIDI
keyboard, instead of using the BANK/DATA control.
✽In STYLE mode, the L2 and L1 always provide the lower harmonies to the original voice and the
H1 and H2 always provide the higher harmonies.
Creating the User Style
The User Style is created by specifying the harmony notes to the original note for the entire octave.
As for an example, let’s make the User Style U1 of major 3rd in C Key (see the chart below).
HARMONY
ORIGINAL C D DE EFGGAABB
EFGABCD
-----
Note 1: The [-] in the chart means that no note is specified. By not assigning the specific note for
the notes not used in melody, it offers the more natural harmony tracking.
Here, we use the PROGRAM A in BANK17 to edit the User Style (U1). Select the PROGRAM A in
BANK17 ([17A Oct Unison] displayed on screen) using the BANK/DATA control and PROGRAM A
button.
1. Press the EDIT button (the EDIT LED lights up). Confirm that the lower line of the screen shows
[STYLE]. (If not, press the < button to move the cursor down to the lower line of the screen and
then select [STYLE] using the BANK/DATA control. Press the EDIT button to move the cursor up
to the upper line of the screen.)

2. Turn the BANK/DATA control to select KEY parameter.
3. Press the < button to move the cursor down to the lower line of the screen and select [C/Am] using
the BANK/DATA control.
4. Press the EDIT button to move the cursor up to the upper line of the screen and select VOICING
parameter using the BANK/DATA control.
5. Press the > button to move down the cursor to the lower line of the screen (H2) and select [U1]
using the BANK/DATA control.
6. Press the EXECUTE/STYLE EDIT button to switch it to the STYLE EDIT screen.
7. Move the cursor using the < button to the ORIGIN and select [C] using the BANK/DATA control.
8. Move the cursor using the > button to H2.
In this example, as we’re making the major 3rd style, set the harmony note at H2 to [E].
Repeat steps 7 and 8 to complete the setting of the harmony notes for the entire octave referring
to the chart.
9. In STYLE EDIT screen, pressing the EDIT button moves the cursor up to the upper line of the
screen and pressing it again returns to the VOICING parameter screen.
✽It is also possible to set the settings using the MIDI note information sent from the external MIDI
keyboard, instead of using the BANK/DATA control.
Note 2: The indication of Style setting changes according to the KEY selected in KEY parameter.
Note 3: The Style editing is available only for the User Style. When the Preset Style is selected,
you can see the settings, but it’s not editable.
The User Styles (U1~U9) are not available for each program, but are common to all programs.
For example, if the U1 is edited in one program, the U1 used in another program is changed as
well.
Copying the Style
This is used when making the User Style based on the Preset Style.
In EDIT mode, while the User Style (U1~U9) is selected in the VOICING parameters, the style can be
copied. Here, we copy the Style of 3A into U2.
1. In EDIT mode, select VOICING parameter using the BANK/DATA control.
2. Press the < button to move the cursor down to the lower line of the screen.
3. Select [U2] using the BANK/DATA control.
4. Press the EXECUTE/STYLE EDIT button to switch it to the STYLE EDIT screen.
5. Press the EDIT button to move the cursor up to the upper line of the screen.
6. Select [COPY STYLE] using the BANK/DATA control.
7. Press the < button to move the cursor down to the lower line of the screen.
8. Select the [3A] using the BANK/DATA control.
9. Pressing the EXECUTE/STYLE EDIT button copies the Style in 3A to the U2 ([COPY COM-
PLETED!] flashes).

10. Pressing the EDIT button to move the cursor up to the upper line of the screen and press it again
to return to the VOICING parameter screen.
✽The User Style name is not changed after copying the style.
In STYLE mode, the Style is set for each harmony part and the various harmonies can be added to
the original voice by the combination of those styles and KEY settings. Find the best suited harmony
by referring to the List of Preset Style.
CHORD
The harmony is set by setting the KEY and selecting one Preset CHORD (harmony pattern) out of 50
Preset CHORDs. As the CHORD is the set of STYLEs, it is not necessary to specify the harmony
pattern to each harmony part, not as in STYLE mode. Selecting just one CHORD sets the harmony of
all harmony parts. The CHORD can be edited to create more complex harmonies and the edited
CHORD can be saved.
✽In CHORD mode, it is important to set the KEY appropriately as in STYLE mode (refer to On Key
in STYLE mode).
CHORD mode parameters
KEY:
Sets the KEY for the song.
CHORDS:
One CHORD out of 50 is selected (refer to the List of Preset CHORD). The CHORD can be edited to
make the original CHORD.Also, the CHORD can be copied and/or renamed.
VOICING:
Sets how harmonies are added to the original voice.
UN: Unison voice added
L8: 1 octave lower voice added
H8: 1 octave higher voice added
HI: Harmony voice higher to the original voice added
LO: Harmony voice lower to the original voice added
Editing the CHORD Program
Here, we use the PROGRAM A in BANK40 to explain editing the CHORD program. Select the
PROGRAMAin BANK40 ([40AChord Demo] displayed on screen) using the BANK/DATAcontrol and
PROGRAM A button.
Before editing, sing into the microphone. The harmonies in unison are added to the original voice. By
editing this program, we will add 2 higher harmonies and 2 lower harmonies to the original voice.
1. Press the EDIT button. Confirm that the lower line of the screen shows [CHORD]. (If not, press
the < button to move the cursor down to the lower line of the screen and then select [CHORD]
using the BANK/DATAcontrol. Press the EDIT button to move the cursor up to the upper line of
the screen.)
2. Turn the BANK/DATA control to select KEY parameter. Confirm that the lower screen line shows
[C/Am]. (If not, select [C/Am] using the steps described above.)

3. Select CHORD parameter using the BANK/DATA control.
4. Press the < button to move the cursor down to the lower line of the screen.
5. Select [01 Normal] using the BANK/DATA control.
6. Press the EDIT button to move the cursor up to the upper line of the screen.
7. Select [VOICING] parameter using the BANK/DATA control. The lower line of the screen shows
[UN, UN, - -, UN, UN].
8. Press the < button to move the cursor down to the lower line (L2) of the screen.
9. Change [UN] to [HI] using the BANK/DATA control.
10. Press the > button to move the cursor to L1 and change [UN] to [HI].
11. Similarly, change [UN] at H1 and H2 to [LO].
Try singing into the microphone again. You can hear the different harmony from the one you heard
before editing. Up to this point, the harmony voices of 2 higher harmonies and 2 lower harmonies
are added to the original voice.
In CHORD mode, the rule in STYLE mode, i.e. L2 and L1 are being the lower harmonies and H1 and
H2 being the higher harmonies to the original voice, does not apply.
The higher harmony is added to the original voice when [HI] is selected in VOICING, and the lower
harmony is added to the original voice when [LO] is selected. For example, when [HI] is set to L2, L1,
H1 and H2, all harmonies added are higher than the original voice. Similarly, when [LO] is set to L2,
L1, H1 and H2, all harmonies added are lower than the original voice. The added harmony notes
depend on the CHORD selected.
✽When [UN], [L8] or [H8] is selected in VOICING parameter, the harmony notes of Unison (UN), 1
Octave Down (L8) and 1 Octave Up (H8) are added regardless of the CHORD.
Editing the CHORD
There are two ways to edit the CHORD.
(1) Editing CHORD from CHORDS parameter
