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.”
