Chapter 6 Creating Rhythm Sets

How Percussion Instruments

Are Organized

Rhythm sets are groups of a number of different percussion
instrument sounds. An instrument consists of the following
four elements.
fig.06-001.e
WG (Wave Generator)
Specifies the PCM waveform (wave) that is the basis of the
sound, and determines how the pitch of the sound will
change.
The XV-5080 has 1083 different waveforms. (See Waveform
List p. 277.) Four waveforms can be assigned to each Rhythm
Tone.
All Rhythm Tones built into the XV-5080 consist of
combinations of Tones which are created based on these
waveforms.
TVF (Time Variant Filter)
Specifies how the frequency components of the Tone will
change.
TVA (Time Variant Amplifier)
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 Tone attacks and decays.

Using a MIDI Keyboard to

Select a Percussion

Instrument for Editing

When setting up Individual Rhythm Tones, you can set
whether you’ll be able to select percussion instruments for
editing only by operating the XV-5080’s front-panel controls
or also by pressing keys on a connected MIDI keyboard.
1. Press [SYSTEM/UTILITY], getting the indicator to light.
* If the indicator is blinking, you are in UTILITY mode. Press
[SYSTEM/UTILITY] once again to make its indicator light.
2. Press [F1 (General)] several times to call up the SYSTEM
General #1 page.
3. Press [ ]/[ ]/[ ]/[ ] to move the cursor to
“Rhythm Edit Key.”
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-5080’s TONE SELECT [1]–[4] buttons.
PNL&MIDI: Percussion instrument sounds can be selected
using the XV-5080’s [E]–[H] buttons and by pressing a key on
a connected MIDI keyboard.
* If you’ve made a mistake, simply press [UNDO]. The value of
the parameter will be restored to what it was when you first
positioned the cursor there.
5. Press [EXIT] to return to the RHYTHM PLAY page.
If you’d like to select percussion instruments using the XV-
5080’s [E]–[H] buttons while playing the sounds on a MIDI
keyboard, select “PANEL.”
