Chapter 6. Creating a Rhythm Set
How Percussion Instruments
Are Organized
A Rhythm Set is a collection of Rhythm Tones, each of which
represents a percussion instrument played on a single key.
An instrument consists of the following four elements.
fig.6-01.e
WG (Wave Generator)
This specifies the PCM waveform (or “wave”) that forms the
basis of the Rhythm Tone – four waveforms can be assigned
to each Rhythm Tone. You can also determine how the pitch
of the Rhythm Tone will change.
The XV-3080 has 1083 different waveforms. (See Waveform
List p. 168.)
All Rhythm Sets built into the XV-3080 consist of Rhythm
Tones based on these waveforms.
TVF (Time Variant Filter)
This sets how the frequency characteristics of the Rhythm
Tone will change.
TVA (Time Variant Amplifier)
This sets how the Rhythm Tone’s volume and stereo
positioning will change.
Envelope
An envelope applies changes to the Rhythm Tone over time.
There are separate envelopes for pitch, TVF (filter) and TVA
(volume). For example, you would use the TVA Envelope to
modify the way in which the Rhythm Tone attacks and
decays.
Using MIDI to Select a
Percussion Instrument for
Editing
You can set whether you’ll be able to select percussion
instruments for editing only by operating the XV-3080’s
front-panel controls or also by pressing keys on a connected
MIDI keyboard.
1. Press [SYSTEM] to make its indicator light.
2. Press [SETUP] to make its indicator light.
3. Use [ ]/[ ] to select the Rhythm Edit Key setting
page.
4. Turn the VALUE dial or by press [INC]/[DEC], to select
the desired value.
PANEL: Percussion instrument sounds can be selected
only by using the XV-3080’s [E]–[H] buttons.
PANEL&MIDI: Percussion instrument sounds can be selected
using the XV-3080’s [E]–[H] buttons and by
pressing a key on a connected MIDI
keyboard.
5. Press [EXIT] to return to the RHYTHM PLAY page.
If you’d like to select percussion instruments using the XV-
3080’s [E]–[H] buttons while playing the sounds on a MIDI
keyboard, select “PANEL.”
