Voice assignment modes

Several voice modes have been added to the Jupiter 6’s voice assign feature. When in either SPLIT

SPLIT

mode, the voice allocation on each voice board can be set independently. This section documents the
entire assignment operation as well as the Europa extensions to it.

Since the Jupiter 6’s keyboard has 61 keys, but can only play six notes at a time, the Jupiter's CPU must
have some way to decide what to do when a key is pressed on the local keyboard or a note is played
through MIDI. The ASSIGN

ASSIGN

mode buttons are used to select how the Jupiter 6 assigns a note to one of

its six voices, or four or two voices when in

split

mode. Each of the nine ASSIGN

ASSIGN

modes in Europa

does this differently, because each mode has different musical uses.

Turning on the VOICE WATCH

VOICE WATCH

feature (as described in the Voice

Voice

(E) – Default: Disabled

section) will help in understanding of the various modes and their functions. By watching which LEDs
turn on, the operation of each of the ASSIGN

ASSIGN

modes becomes obvious. This is also a handy way of

identifying an out of tune or nonfunctional voice (great for the service tech!). Each voice mode is
described in detail in this section:

Solo [Solo assign LED lit solid]

Solo [Solo assign LED lit solid]
Pressing the SOLO

SOLO

button once (from any assign mode other than SOLO

SOLO

mode being set already) lights

the SOLO

SOLO

button’s LED solid and puts the board in SOLO

SOLO

mode. SOLO

SOLO

Mode will only sound one

note at a time - the last note played. If a note is held down and another note played, the voice will jump to
the new note, but the envelope will not retrigger. This allows playing of smooth solo lines. If the second
note is released before the first note, the first note will sound again. If the sound quickly dies away, try
increasing the SUSTAIN

SUSTAIN

level of ENV

ENV

ENV----2

. A patch with a quick ATTACK

ATTACK

and D

DECAY

ECAY

with no

SUSTAIN

does not work well in SOLO

SOLO

mode because the envelope only gets retriggered when all

notes are released. Only one voice is used in SOLO

SOLO

mode.

Solo rotate [Solo assign LED blinking]

Solo rotate [Solo assign LED blinking]
Pressing the SOLO

SOLO

button a second time makes the SOLO

SOLO

button's LED blink and puts the board in

SOLO

ROTATE

mode. As with SOLO

SOLO

mode, SOLO

SOLO

ROTATE

sounds only the last note played.

However, each new note is assigned to a new voice, which makes the envelope retrigger for each new
note. This is good for playing short, percussive sounds with a long RELEASE

RELEASE

, because new notes will

not immediately interrupt the RELEASE

RELEASE

with a new ATTACK

ATTACK

like in SOLO

SOLO

mode (unless many notes

are played quickly). All available voices are used in SOLO

SOLO

ROTATE

mode.

Solo unison [Solo and

Pressing the SOLO

SOLO

and UNISON

UNISON

buttons at the same time lights both the SOLO

SOLO

and UNISON

UNISON

LEDs

and puts the board in SOLO

SOLO

UNISON

mode. The SOLO

SOLO

UNISON

mode works just like SOLO

SOLO

mode, only all available voices are used to play each note. If the board is in WHOLE

WHOLE

mode, six voices

sound at one time, and in SPLIT

SPLIT

mode either four or two. This makes for some very fat sounds. The

fatness can be adjusted by using the UNISON

UNISON

DETUNE

knob just to the left of the ASSIGN

ASSIGN

buttons.

A setting of 0

tunes the voices very close together, while a setting of 10

detunes the voices so much that

it starts sounding nasty - but not a good sort of nasty.
