● What each parameter does
On this unit, parameter settings are made for each Part. In other words, parameter
values belong to Parts, and not to sounds (Instruments). For example if you set Vibrato
Rate to +20 and then select a different sound for that Part, the Vibrato Rate of +20 will
apply to the newly selected sound (not the initial value of
±
0). In this way, parameters
belonging to Parts are called Part Parameters.
* Parameters such as Vibrato, Filter and Envelope can be set not only for Parts, but also for
sounds (Instruments). Sounds you create by modifying these parameters are called User
sounds, and can be stored in Native map memory area (p.97).
Vibrato
Vibrato is an effect created by modulating the pitch. Applying vibrato makes the sound more expressive.

❍ Vibrato Rate: -64 — +63
This parameter adjusts the speed (frequency) of the
pitch modulation. Positive (+) settings make the pitch
modulation faster, and negative (-) settings make it
slower.
❍ Vibrato Depth: -64 — +63
This parameter adjusts the depth of the pitch modula-
tion. Positive (+) settings make the pitch modulation
deeper, and negative (-) settings make it shallower.
❍ Vibrato Delay: -64 — +63
This parameter adjusts the time required for the vibra-
to effect to begin. Positive (+) settings increase the
time before vibrato will begin, and negative settings
shorten the time.
Filter
By modifying the filter settings, you can control the tim-
bre (tone) of the sound. The type of filters in this unit
are called Low Pass Filters, and allow only frequencies
lower than a specified frequency to pass. This frequen-
cy is called the Cutoff Frequency. By modifying the
setting of the Cutoff Frequency you can make the
sound brighter or darker. The Cutoff Frequency can
change over time, controlled by the “envelope”. By
adjusting the filter and envelope settings, you can cre-
ate sounds that have movement and expression.
