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

Rhythm Set

Note Number 98 (D7)

Note Number 97 (C#7)

Note Number 36 (C2)

Note Number 35 (B1)

Rhythm Tone (Percussion instrument sound)

	WG		TVF		TVA
	Pitch		TVF		TVA
Envelope		Envelope		Envelope

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.”
