Roland XV-3080 用户手册

The type of sound most commonly played on the XV-3080 is 
called a 

. Each Patch can contain up to four Tones.

fig.4-01.e

You can turn the Tones in a Patch on or off. Only Tones that 
are turned on are heard when you play the Patch. (p. 84)

You can also specify how Tones 1 and 2 and Tones 3 and 4 
will be combined (Structure). (p. 88)

Tones are the smallest programmable unit of sound on the 
XV-3080, and are the basic building blocks that make up a 
Patch. You can’t play a Tone by itself – it can only be played 
as part of a Patch or Rhythm Set. A Tone consists of the 
following five components.

fig.4-02.e

This selects the PCM waveform material that provides the 
basis of the Tone. Two waveforms can be assigned to each 
Tone. 

The XV-3080 has 1083 different waveforms. (See Waveform 
List p. 168.) 

All Patches built into the XV-3080 consist of combinations of 

Tones based on these waveforms.

This specifies how the frequency components of the Tone 
will change.

This determines how the volume and panning of the Tone 
will change.

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.

Use the LFO to create cyclical changes – or cyclical 
“modulation” – in a Tone. Each Tone has two LFOs. 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.

Example 1:A Patch consisting of only one Tone
                 (Tones 2–4 are turned off).

Example 2: A Patch consisting of four Tones.
