Create Original Sounds
The two knobs located in the lower left area of the panel can be used to
add variations to the sound being played, transforming the sound in a
variety of musical ways. Filter, envelope generator, and other effects
can be assigned to the two knobs as required. In this section we’ll
explain how effects can be assigned to the knobs, and provide a few
tips for their use.
Repeatedly press the [ASSIGN] button to sequentially select the five effect combinations provided: z →
x → c → v → b → z → ... etc. The currently selected combination is shown in the display.
z–c affect the main and dual voices only. Split voices will not be affected. Styles and songs will also not
be affected.
v–b affect styles only.
