Basics
Section
7 AMP (Amplitude) and AEG
(Amplitude EG) Screens
Set the volume of each Element after the OSC
(Oscillator), PITCH and FILT (Filter) parameters
have been applied, and also the final overall
volume of the signal sent to the outputs.
The signal of each Element is sent at the
specified volume to the next Effect Unit.
Also, by setting the AEG (Amplitude Envelope
Generator), you can control how the volume
changes over time.
The final volume for all Elements is set in the
Volume (Vol) parameter of the QED screen in
Common Edit.
• Amplitude EG (Envelope Generator)
Using the AEG, you can control the transition in
volume from the moment a note is pressed on the
keyboard to the point at which it is released.
As illustrated below, the Amplitude Envelope
consists of five Time (transition speed)
parameters and five Level parameters (for the
amount of filtering). When you press a note on
the keyboard, the volume will change according
to these envelope settings. Furthermore,
different AEG parameters can be set for each
Element.
Details about AEG parameters are given on Page
83.

LFO AEG
8 LFO (Low Frequency
Oscillator) Screens
As its name suggests, the LFO creates 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, although the actual available LFO
parameters will vary according to the type of
Element.
9 EQ (Equalizer) Screens
Specific frequency bands for each Element can be
attenuated or boosted using an equalizer. There
are many types of equalizers available. Details
are given on Page 86.
) Storing Edited Voices
Up to 128 new/edited Normal Voices and 2
new/edited Drum Voices can be stored to
internal user memory or external Memory Card.
The maximum number of Plug-in Voices that can
be stored to internal memory (PLG) is 64.
When storing a Voice, any existing data at the
storage location will be lost. You should always
back up important data to Memory Card, computer
or some other storage medium beforehand.
Details about storing Voices are given on Page 101.
