Roland JUNO-Di Editor Owner's Manual page 10

Overview
The JUNO-Di will enter Performance mode if you turn on Split, Dual,
or Super Layer. Of the sixteen parts of the performance, Split or Dual
use parts 1 and 2, and Super Layer uses parts 1 through 5.
When you turn on each of these functions, the settings of the JUNO-Di
will be as follows.
When you turn Split on
Split refers to settings for the key ranges of parts 1 and 2 that result in
them being separated into upper and lower zones. The lowest key of
the upper zone is called the split point.
Parts 1 and 2 will be assigned as follows. The indication shown on the
display screen of the instrument itself is given in parentheses ( ).
Part name Key range
Part 1: UPPER (U)
From the split point key to G9
From C-1 to one key to the left of the split
Part 2: LOWER (L)
point
When you turn Dual on
Dual refers to settings in which the key ranges of parts 1 and 2
overlap. The indication shown on the display screen of the instrument
itself is given in parentheses ( ).
Part name Key range
Part 1: PART 1 (1)
C-1--G9
Part 2: PART 2 (2)
C-1--G9
When you turn Super Layer on
The sound of part 1 will be assigned to parts 1--5, and the following
settings will be made.
Parameter Value Explanation
Layer
2--5 The number of parts used.
Detune (FINE TUNE) will be applied to
parts 2--5.
Detune
0--30
10
Part 2: 0--30
Part 3: This will be the inverse of the
part 2 value. For example, if
part 2 is set to "+2," part 3
will be set to "-2."
Part 4: This will be 1.5 times the
value of part 2.
Part 5: This will be 1.5 times the
value of part 3.
How a Patch is Structured
Patches are the basic sound configurations that you play during a
performance. Each patch can be configured by combining up to four
tones. Each tone can be turned on/off individually, allowing you to
select the tones that will produce sound.
Patch

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

Example 2: A Patch consisting of four Tones.
Tones
On the JUNO-Di, the tones are the smallest unit of sound. However, it
is not possible to play a tone by itself. The patch is the unit of sound
which can be played, and the tones are the basic building blocks
which make up the patch.

Pitch
Envelope Envelope
audio signal
WG (Wave Generator)
Specifies the PCM waveform (wave) that is the basis of the sound, and
determines how the pitch of the sound will change.
TVF (Time Variant Filter)
Specifies how the frequency components of the sound will change.
TVA (Time Variant Amplifier)
Specifies the volume changes and the sound's position in a stereo
soundfield.
Envelope
You use Envelope to initiate changes to occur to a sound over time.
There are separate envelopes for Pitch, TVF (filter), and TVA (volume).
