About EG Rate and Time (Voice Mode)
The EG (Envelope Generator) processes and shapes
the output level of the tone generator from the
moment you press a key until the sound decays to
silence. The level (Y-axis in the illustrations below)
is a different aspect of the sound, depending on
which EG is being used. For the PEG, level
corresponds to Pitch. For the FEG, it corresponds to
the cutoff frequency. For the AEG, it corresponds to
the volume.
The behavior of the EG over time is controlled by
the Rate (R) parameters. Rate refers to the time it
takes to go from one level to the next (for example,
from the initial level to the attack level).
The illustrations below show how different Rate
settings affect the sound. To extend the time
between level changes and make it long, set the Rate
(R) to a small value.

LFO (Low Frequency Oscillator)
In PAGES 32 to 35, you can edit the LFO, which (as
its name suggests) produces waveforms of a low
frequency. These waveforms can be used to vary
the pitch, filter or amplitude of each Element to
create effects such as vibrato, wah and tremolo.
However, the actual available LFO parameters will
vary according to the type of Element.
The LFO is capable of producing a wide variety of
effects in various ways. By modulating the pitch
over an adjustable amount, it creates vibrato. By
modulating the filter over an adjustable range of
frequencies, it creates wah-wah and dynamic filter
sweep effects. By modulating the volume (or
“amplitude”) of the sound over an adjustable depth,
it creates tremolo.

Storing Edited Voices
Up to 128 new/edited Normal Voices and 2 new/edited
Drum Voices can be stored to internal user memory.
When storing a Voice, any existing data at the storage
location will be lost. You should always back up
important data to computer or some other storage
medium beforehand.
