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.

3. Connect the AC Adaptor and press the POWER switch to turn the unit on.

4. When the unit is turned on, the selected BANK number, PROGRAM (A or B) and its name appear on the upper line of the screen. The part of its program parameters appear on the lower line of the screen.

5. Press the BYP ASS button to turn the BYP ASS of f (BYP ASS LED is of f) and sing into the microphone. Adjust the INPUT LEVEL control to set the input level as high as possible in the range that the OVER (RED) LED of the Input Level Indicator will not light up. The output terminal provides the original vocal sound mixed with the harmonies.

6. Set the signal output level using the OUTPUT LEVEL control. 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

Switch the bank using the BANK/DA T A control and select the program with the PROGRAM A/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 programs 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, such as STYLE, MODAL, etc., is shown at the lower right side of the screen when the program is 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).
