Voices – Playing the Keyboard –

 Super Articulation Voices

The word “articulation” in music usually refers to the transition or continuity

between notes. This is often reflected in specific performance techniques, such as

staccato, legato and slur. Two types of Voices—Super Articulation (SA) Voices

and Super Articulation 2 (SA2) Voices—enable you to create these subtle musical

expressions, simply by how you play.

SA Voices (S.Articulation!)

The SA Voices provide many of same benefits as the MegaVoices, but with

greater playability and expressive control in real time.

For example, with the Saxophone Voice, if you play a C and then a D in a

very legato way, you will hear the note change seamlessly, as though a saxo-

phone player played it in a single breath. Similarly with the Concert Guitar

Voice, the D note would sound as a “hammer on”, without the string being

plucked again.

Depending on how you play, other effects such as subtle sound produced

when the keys are released or sustain sound that occur when you press the

damper pedal of a grand piano (for the Grand Piano Voice), shake or breath

noises (for the Trumpet Voice), or finger noises (for the Guitar Voice) will be

produced.

SA2 Voices (S. Articulation2!)

For wind instrument Voices and Violin Voices, a special technology called

AEM has been used, which features detailed samples of special expressive

techniques used on those specific instruments—to bend or slide into notes, to

“join” different notes together, or to add expressive nuances at the end of a

note, etc.

You can add these articulations by playing legato or non-legato, or by jump-

ing in pitch by around an octave. For example, using the Clarinet Voice, if

you hold a C note and play the Bb above, you’ll hear a glissando up to the Bb.

Some “note off” effects are also produced automatically when you hold a

note for over a certain time.

Each SA2 Voice has its own default vibrato setting, so that when you select a

SA2 Voice, the appropriate vibrato is applied regardless of the Modulation

wheel position. You can adjust the vibrato by moving the Modulation wheel.

You can also use the [ART. 1]/[ART. 2] buttons to add articulations to the SA and

SA2 Voices (page 40).

For details on how to best play each SA and SA2 Voice, call up the information

window (pressing the [6 ] (INFO) button in the Voice Selection display.)

For more information on AEM technol-

ogy, see below.

NOTE

The characteristics of SA2 Voices

(default vibrato setting and articulation

effects applied by the [ART] buttons) are

effective for real-time performance;

however, these effects may not be com-

pletely reproduced when you play back

a Song which has been recorded using

SA2 Voices.

NOTE

AEM Technology

When you play the piano, pressing a “C” key produces a definite and relatively fixed C note. When you play a

wind instrument, however, a single fingering may produce several different sounds depending on the breath

strength, the note length, the adding of trills or bend effects, and other performance techniques. Also, when

playing two notes continuously—for example “C” and “D”—these two notes will be smoothly joined, and not

sound independent as they would on a piano.

AEM (Articulation Element Modeling) is the technology for simulating this characteristic of instruments. Dur-

ing performance, the most appropriate sound samples are selected in sequence in real time, from huge quanti-

ties of sampled data. They are smoothly joined and sounded—as would naturally occur on an actual acoustic

instrument.

This technology to smoothly join different samples enables the application of realistic vibrato. Conventionally

on electronic musical instruments, vibrato is applied by moving the pitch periodically. AEM technology goes

much further by analyzing and disaggregating the sampled vibrato waves, and smoothly joins the disaggre-

gated data in real time during your performance. If you move the Modulation wheel when you play the SA2

Voice (using AEM technology), you can also control the depth of the vibrato, while maintaining its realistic

quality.
