How simultaneous note numbers and Voices are related

Concerning legato-enabled sounds

24
The sounds of this unit consist of units called "Voices". There is a limit to how many
of these "Voices" can sound at once, and in the case of this unit, up to 64 simultaneous
voices can be used. Some sounds (Instruments) use 1 voice and others use 2 voices
(Instrument list, p.154). The main reason that some sounds use 2 voices is to allow dif-
ferent timbres to be produced by different velocity values.
If more than 64 voices are used at once, later-sounded notes will be given priority,
and notes sounded previously will be turned off starting from the oldest. If you use only
single-voice instruments, you will be able to play 64 notes simultaneously, but if some of
the instruments are 2-voice, you will be able to play less than 64 simultaneous notes.
Even if a MIDI Note Off message (p.131) is received, voices will be used for as long as
the sound is heard. Be aware of this especially in the case of sound with a long release
(p.33).
* If song data created with 64 voice playback in mind is played back on a sound source with fewer
voices, some notes will drop out, and the musical result will not be as it should. The SC-55 has
24 voices, and the SC-55mkII has 28 voices.
This unit provides legato-enabled sounds that are ideally suited to legato playing, and
which can realistically simulate this instrumental performance technique.
To understand this feature, consider how most string instruments produce sound.
Usually, a brief attack-like sound will be heard only at the very instant the string is made
to vibrate. After that a much mellower, attack-free sound continues to emanate during
the string's vibration. The legato-enabled sounds simulates such variable attack-portion
characteristics of string sounds by switching on or off certain special voices within an
Instrument according to the way the keyboard is played.

Try out one of these Patches to hear how it works. If you are using a keyboard, play a
note and keep your finger on that key while playing another note.
You should hear a distinct attack portion with the first note you play, while the second
one contains almost no attack components, and sounds much smoother.
At this time, " " will be displayed following " " of the instrument name.
If you want to sound the attack portion each time, simply release your finger from a
key before playing the next note.

edit an Instrument that meets your intended usage.
