PATCH WG (Patch Wave Group)
This set of parameters allows you to select the PCM waveform that serves as the basis for the currently
selected Tone, apply effects to the waveform, and control its pitch.

This produces a time delay between the moment a key is pressed (or released) and the moment the Tone
actually begins to sound. Since you can adjust the timing of each Tone in a Patch, you can create effects in
which pressing a single key produces two or more sounds occurring at different times. If you don't wish to
use Tone Delay, set Tone Dly to NORMAL and Tone Delay Time to 0.

NORMAL: The Tone sounds after the
specified Delay Time.

KEY-OFF-NOR: The Tone doesn't
sound while the key is being pressed, but
sounds after the specified Delay Time
when the key is released.

Description
Chooses the desired waveform's group.
INT: Internal
EXP-A, B: Wave Expansion Boards A, B
* It's not possible to select EXP-A, B unless a wave expansion board
is inserted into the corresponding slot.
Chooses the desired waveform. You can choose a separate
waveform for the XV-2020's left and right channels.
* For monaural tones, assign a waveform to the L channel. No
sound will be heard if a waveform is set for only the R channel.
Sets the manner in which the Tone sounds.
* If you've selected a Wave that is a decay-type sound (i.e., a sound
that fades away naturally even if the key is not released), selecting
KEY-OFF-NOR or KEY-OFF-DCY may result in no sound being
heard.
HOLD: The Tone will only sound if the key is held for longer
than the specified Delay Time. If the key is released before the
Delay Time has elapsed, the Tone will not sound.
Delay Time

KEY-OFF-DCY: The Tone doesn't sound while the key is be-
ing pressed, but sounds after the specified Delay Time when
the key is released. However, for this setting—unlike KEY-
OFF-NOR—the TVA envelope of the Tone begins when the
key is first pressed. As a result, in most cases, only the decay
portion of the sound is heard.

Specifies the time after which the Tone sounds when using
Tone Delay. When the Structure Type parameter has a setting
of 2–10, the outputs of Tones 1 (3) and 2 (4) are combined with
Tone 2 (4). Tone 1 (or 3) settings are ignored.
Specifies the gain (or amplitude) of the waveform. An increase
of 6 dB doubles the waveform's gain. If you intend to use the
Booster to distort the waveform's sound, set this parameter to
its highest value.
