Roland XV-5080 Selecting the Tones That Will Sound Tone On/Off, Multi-partial Patch, 126

Chapter 4 Creating Patches

Multi-partial Patch

Patches using data loaded into the XV-5080 from sampler

Multi-Partial Patch
B1	Partial
D7	Sample 1
	Sample 2
	Sample 3
	Sample 4
	88 Partials

libraries are of this type.

Multi-Partial Patches are created by assigning the constituent sounds, called Partials, to the keys on the keyboard, with up to 88 Partials being assignable.

One difference between Tones and Partials is that whereas Tones are composed of two waveforms, Partials may contain up to four samples (Wave data).

*Multi-Partial Patches are created using samples (Wave data) loaded into the SIMM (memory module) (internal Waves cannot be used). To do this, you need a separate device to load the samples from a sampler library or other source to the XV- 5080. (p. 181)

How a Partial Is Organized

The sounds from which Multi-Partial Patches are composed

are called Partials. Partials may comprise up to four samples, and are composed using the following five elements.

SMT (Sample Mix Table)

Selects the sample to be used as the source of the sound. You can use the key touch and MIDI messages to control the way each sample is played.

TVF (Time Variant Filter)

Specifies how the constituent frequencies of the Tone will change.

TVA (Time Variant Amplifier)

Specifies how the volume will change, and controls the localization.

Envelope

An envelope applies changes to the 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.

The TVF envelope can be used to change not only the cutoff frequency, but also the pitch.

LFO (Low Frequency Oscillator)

Use the LFO to create cyclical changes—or cyclical “modulation”—in a Tone. Each Tone has an LFO. An LFO can be applied to the Tone’s pitch settings, TVF (filter), and TVA (volume). When an LFO is applied to pitch, a vibrato effect is produced. When an LFO is applied to the TVF cutoff frequency, a wah-wah effect is produced. When an LFO is applied to the TVA volume, a tremolo effect is produced.

Selecting the Tones That Will Sound (Tone On/Off)

Here’s how to turn on the Tones that you want to hear in a Patch. You can also use the on/off technique described in this section to audition an individual Tone by turning off all the other Tones in a Patch.

Select the Patch you wish to use.

1.Make sure that the PATCH PLAY page is displayed.

2.Hold down [SHIFT] and press TONE SW [1]–[4] to switch the corresponding Tone on so that its indicator lights, or off so that its indicator goes dark.

3.The PATCH PLAY page indicates the Tones that are on as follows. Tones that are off are shown as “-.”
