Voices & Multis
Voice Edit StructureOne voice consists of Oscillator, Pitch, Filter, Amplitude, LFO and various parameters as shown on page 25.
You can create the basic voice character by setting these five parameters.
●Oscillator
This unit outputs the wave of each Element. You can
set the note range for Element (the range of notes on
the keyboard over which the Element will sound) as
well as the velocity response (the range of note
velocities within which the Element will sound).
For example, you could set one Element to sound in an
upper range of the keyboard, and another Element to
sound in a lower range. Thus, even within the same
Voice, you can have two different sounds for different
areas of the keyboard or you can make the two Element
ranges overlap so that their sounds are layered over a
set range. Furthermore, you can set each Element to
respond to different velocity ranges so that one
Element sounds for lower note velocities, whereas
another Element sounds for higher note velocities.
●PITCH
This unit controls the pitch of each Element output
from OSC.
You can detune separate Elements, apply Pitch Scaling
and so on. Also, by setting the PEG (Pitch Envelope
Generator), you can control how the pitch changes
over time.
PEG (Pitch Envelope Generator)
Using the PEG, you can control the transition in pitch
from the moment a Note On message is received to the
point at which the sound stops. As illustrated below,
the Pitch Envelope consists of five Time (transition
speed) parameters and five Level (pitch) parameters.
This is useful for creating automatic changes in pitch.
Furthermore, different PEG parameters can be set for
each Element.
●Filter
This unit modifies the tone of each Element output
from Pitch by cutting the output of a specific frequency
portion of the sound.
You can also set the Filter Envelope Generator (FEG),
to control how the filter works over time — letting you
set up dynamic changes in tone.
Cutoff Frequency and Resonance
Filters work by allowing the portion of the signal lower
than a given frequency to pass, and cutting the portion
of the signal above that frequency. This frequency is
referred to as the cutoff frequency. You can produce a
relatively bright or darker sound by setting the cutoff.
Resonance is a parameter that boosts the level of the
signal in the area of the cutoff frequency. By
emphasizing the overtones in this area, this can
produce a distinctive “peaky” tone, making the sound
brighter and harder.
