Chapter 2. Creating Your Own Sounds
Chapter 2
Selecting the Fundamental 
Waveform (WAVE, VARIATION)
[WAVE]
Select the waveform groups on which the synthesizer’s sounds are 
based. Each time [WAVE] is pressed, the selected waveform group is 
switched in the order shown right.
Holding down [WAVE] and pressing [VARIATION] switches 
the waveform groups in the reverse order of that shown right.
[VARIATION]
Each waveform group selected by pressing [WAVE] features a 
number of variations, providing you with an even wider sound 
palette. Pressing [VARIATION] switches the variations in order of 
variation number. Once you have selected a variation, press [EXIT].
By holding down [VARIATION] and pressing [WAVE], you can 
switch the variations in the reverse order. You can also select 
variations by pressing [VARIATION] and then pressing 
[VALUE ▼/▲].
• The number of variations differs with the waveform group.
• “
” (PWM waveform) includes no variations.
Waveform Group
Number of 
Variations
Description
 
(Sawtooth Wave) 
12 (1–12)
Often used in creating 
characteristic synthesizer 
sounds. Variation 12 is 
constructed from multiple, 
detuned, sawtooth waves 
layered together.
 
(Square Wave) 
10 (1–10)
Often used in creating 
characteristic synthesizer 
sounds. The subtle differ-
ences in waveforms that a 
variety of popular, classic 
synthesizers had can be ex-
pressed through switching 
variations.
 
(Pulse Wave) 
9 (1–9)
The Pulse group contains 
nine pulse wave variations 
you can switch through, 
with duty cycles ranging 
from 5% to 45%, set in mul-
tiples of 5%.
 
(PWM Wave) 
1 (N/A)
With this waveform, you 
can have the pulse width 
of a square wave change 
periodically. Use this 
when you want to create 
subtle changes in the tone.
 
(Triangle Wave/
Sine Wave)
5 (1–5)
This tone includes few har-
monics and no unusual 
characteristics. The subtle 
differences in waveforms 
that a variety of popular, 
classic synthesizers had 
can be expressed through 
switching variations.
SPECTRUM 
20 (1–20)
You can select waveforms 
that are difficult to achieve 
with general analog syn-
thesizers, such as voice-
type waveforms and other 
waveforms with special 
harmonic structures and 
waves with formants.
NOISE
10 (1–10)
Select from different noise 
types, including white 
noise, pink noise, and 
noise for which the pitch 
can be changed with the 
keyboard.
