This process repeats as many times as you press the TONE button.
All of the other EDIT buttons work in the same way — any of the parameters
accessed by an EDIT button can be selected by pressing the same EDIT button
repeatedly until the letter representing the desired parameter begins to flash. Once
the desired parameter has been selected, its value can be edited by using the -1
and +1 buttons or by directly entering the value using the number buttons (0
through 9). When a parameter is selected that has a range from ''—' to "+" values,
the "+/-" button located to the right of the +1 button can be used to change a "+"
setting to a '—' one, and vice versa.
Once the required edits have been made, you can press another EDIT button to
access and edit other parameters, press the STORE button to access the STORE
function that allows you to store your creation in a USER memory
location, or
select any other mode by pressing the appropriate button.

This parameter changes the brilliance of the voice. Brilliance can be increased by
setting "+" values, or reduced by setting "-" values.
This parameter actually changes the timbre of the voice by altering its harmonic
structure. The audible change produced will depend to a large degree on the
original voice data.
The Volume parameter adjusts the volume of the voice. This is handy since chang-
ing the Tone and or Wave values can significantly alter the perceived volume of the
voice. Use Volume to set the voice to the required volume level. Volume can be
increased by setting "+" values, or reduced by setting '—' values.
The AMP EG button accesses three parameters that shape the "amplitude enve-
lope" of the voice. The amplitude envelope determines how fast the attack of the
sound
is, how quickly the sound decays after the attack, and how quickly the
sound level returns to zero after the note (key) is released. In addition to the tone
or timbre of the sound, the amplitude envelope is one of the most important
factors in "identifying" a specific voice. A simple graphic representation of an
amplitude envelope is given below.
