Cautions When Using a One-shot
Waveform
It is not possible to use the envelope to modify a one-shot
waveform to create a decay that is longer than the original
waveform, or to turn it into a sustaining sound. If you were
to program such an envelope, you would be attempting to
shape a portion of the sound that simply doesnt exist, and
the envelope would have no effect.
Cautions When Using a Loop
Waveform
With many acoustic instruments such as piano and sax,
extreme timbral changes occur during the first few moments
of each note. This initial attack is what defines much of the
instruments character. For such waveforms, it is best to use
the complex tonal changes of the attack portion of the
waveform just as they are, and to use the envelope only to
modify the decay portion. If you attempt to use the envelope
to modify the attack portion as well, the characteristics of the
original waveform may prevent you from getting the sound
that you intend.

Functions of Patch
Parameters
This section explains the functions the different Patch
parameters have, as well as the composition of these
parameters.
fig.05-01
Parameters marked with a can be controlled using
specified MIDI messages (Matrix Controller). Settings in
the Matrix Control page will determine how these
parameters are controlled (p. 78, p. 79).
Settings Common to the Entire
Patch (COMMON)
On this display you can assign a name to a Patch and set the
volume and pan of the entire Patch.
PATCH NAME
fig.05-07
You can assign a name of up to 12 characters to the Patch.
For details on assigning names, refer to Assigning a
Name (p. 28).
PATCH CATEGORY
fig.05-08
Category (Patch Category)
Specifies the type (category) of the Patch.
The Patch Finder function uses this setting. It also determines
the phrase that will be sounded when using the Phrase
Preview function.
For details on the possible category names, refer to (p.
