Roland XV-3080 Modifying a Rhythm Tone’s Waveform and Panning Wave, Tone Name, WMT Wave, 113

note is held, allowing wave memory to be used more efficiently. The XV-3080’s looped waveforms also include components of other sounds, such as piano-string resonant vibrations and the hollow sounds of brass instruments.

The following diagram shows an example of a sound – an electric organ – that combines one-shot and looped waveforms.

Notes for Editing One-Shot Waveforms

You cannot give a one-shot waveform a longer decay – or make it into a sustaining sound – by using an envelope. If you were to program such an envelope, you would be attempting to shape a portion of the sound that simply doesn’t exist, and the envelope would have no effect.

Notes for Editing Looped Waveforms

With many acoustic instruments such as piano and sax, extreme timbral changes occur during the first few moments of each note. This initial attack is what defines much of the instrument’s character. The XV-3080 provides a variety of waveforms containing realistic acoustic instrument attacks. To obtain the maximum realism when using these waveforms, it is best to leave the filter wide-open during the attack so that all of these important timbral changes are heard. If you use an envelope to modify the attack portion, you may not achieve the result you want. Use enveloping to produce the desired changes in the decay portion of the sound.

If you try to make a waveform’s attack brighter by lowering the high-frequency content of its decay using the TVF filter, consider the original timbral character of the waveform. If you’re making a part of the sound brighter than the original

waveform, you should first generate new upper harmonics not present in the original waveform using the Color and Depth parameters (FXM) before filtering. This will help you achieve the desired result. To make an entire waveform brighter, try applying effects such as an enhancer and equalizer before modifying the TVF parameter (RHYTHM/ TVF).

TONE NAME

You can name a Rhythm Tone using up to 12 alphanumeric characters.

Use [	]/[	] to move the cursor, and then turn the
[VALUE] knob or press [INC]/[DEC] to select the desired
character.

Press [SHIFT] to display the following in the bottom right corner of the screen.

A a: Switches between uppercase and lowercase characters.

INS: Inserts a space at the cursor location and shifts the remaining text to the right by one character position.

DEL: Deletes the character at the cursor and shifts the remaining text one character position to the left.

Press each of these buttons in order to execute its corresponding function (refer to the figure).

WMT WAVE

With the XV-3080, up to four stereo Waves can be assigned to a single Rhythm Tone. You can select the way tones sound according to the force with which the keys are played, thus allowing you to create Rhythm Tones featuring great expressive power. This function is called WMT (Wave Mix
