Q&A
Sound Engine
15  What is the meaning of “MODEL” in a model 
bank?
A model is a sound engine that reproduces the sounds and parameter 
changes of famous vintage analog synthesizers and other historical 
instruments.
Some models provide not only the sounds that were found on the 
original, but also newly re-created sounds.
16  What varieties of “MODEL” are provided? 
Seven types are provided: JUPITER-8, JUNO-106, JX-8P, SH-101, XV-
5080, RD (Piano), and VOCODER.
17  Can a model be used with more than one part? 
This depends on the model.
“RD” and “VOCODER” can be used only with part 1.
Other models can be used with parts 1–4.
18  Can a drum kit be used with any part? 
No, a drum kit can be used only with part 5.
It cannot be used with parts 1–4.
19  Is the unit equipped with a vocoder? 
Yes, it is.
To use the vocoder, proceed as follows (with the factory settings).
1. Connect a dynamic microphone or an electret 
condenser microphone to the rear panel MIC IN jack.
2. Adjust the MIC GAIN.
3. Select part 1, and then press the [MODEL BANK] 
button to make it light.
4. Press the [MODEL BANK] button and then press 
button [15].
* With the factory settings, “VOCODER” is assigned to the model bank of 
the [15] button. 
You can change the model bank that is assigned. 
& “Customizing the model bank” (p. 15)
5. Use knob [1] to select a vocoder sound (two types).
6. While playing the keyboard, vocalize into the 
microphone.
The vocoder eect is applied.
* Phantom-powered condenser microphones are not supported.
20  Can I input audio playback from my computer 
instead of audio from the mic input, and apply 
the vocoder?
Yes, you can.
1. Connect the JUPITER-X/Xm with your computer via 
USB.
2. Choose “OUT MIC” as the audio output device of your 
computer.
Now the audio playback of your computer can be used for 
vocoder performance.
21  What is the maximum simultaneous 
polyphony?
It diers depending on the type and combination of models.
As an example, if the JUPITER-8 is assigned to all four parts, the 
maximum simultaneous polyphony will be 32 voices (up to eight 
voices per part).
In the case of PCM sounds, up to 256 notes (for MONO) can be 
produced.
22  When JUNO-106 or SH-101 is selected, why 
can’t the OSC [TYPE] knob change the type?
On the JUNO-106 and SH-101 synthesizers, the sound is created by 
adjusting the volume of (or turning on/o) PW (square wave / pulse 
wave), SAW (sawtooth wave), SUB OSC (sub oscillator), and NOISE 
(noise) respectively.
This means that these models do not use the concept of selecting an 
oscillator waveform, and therefore the OSC type cannot be changed.
Create the sound as follows.
1. Select JUNO-106 or SH-101.
If you want to start editing from the simplest possible sound, 
use “TONE INITIALIZE” to initialize the tone.
& “23 Can I edit from the initialized sound of a model?” (p. 55)
2. Use the [OSC1]–[OSC4] sliders to adjust the volume 
(or turn it on/o).
[OSC1] slider: PW (square wave / pulse wave)
[OSC2] slider: SAW (sawtooth wave)
[OSC3] slider: SUB OSC (sub oscillator)
[OSC4] slider: NOISE (noise)
