The Arpeggiator

The arpeggiator takes notes you play on the keyboard and generates a pre-
programmed phrase based on those notes. Each of these phrases is called a
"style. " The JUNO-Di contains 128 styles. Arpeggios can be great for creating
repeating patterns such as those used in dance music, and can also produce
automatic bass lines that begin with the note you play on the keyboard.
Let's explore how arpeggios work on the JUNO-Di.
Start by selecting a polyphonic patch
1
To turn on the arpeggiator, press the ARPEGGIO button so
2
it lights and the ARPEGGIO screen appears.
On the ARPEGGIO screen, you can customize the arpeggio to be
played in a variety of ways, as explained on Page 67 of the Owner's
Manual.
Hold down some notes on the keyboard and try out the available
3
arpeggio styles.
As you listen, move your fingers around to different keys to hear how
4
your notes interact with the current arpeggiator style.
If you'd like to play some notes and then just let go as the arpeggiator
takes over, turn the Arpeggio Hold parameter on.
Let go of the keys—or turn off Arpeggio Hold—when you're done
5
experimenting.
Select the monophonic Synth Patch 023: Hot Coffee. It plays one note
6
at a time, no matter how many keys you press. The arpeggiator does
some very interesting things to mono patches.
Play around a bit more with the arpeggio styles as you play different
7
notes with Hot Coffee.
To turn the arpeggiator off, press the ARPEGGIO button again to
8
unlight it.

Chord Memory

The JUNO-Di's Chord Memory feature generates a chord based on a single
key you play on the keyboard. The chord can be set up to play its notes in
several ways. A "chord set" is an octave's worth of chord structures assigned
to keys—the actual notes they play are based on the key you're in. There are
17 factory chord sets.
Let's try out this feature using the first GUITAR/BASS patch, 001 JUNO
Nylon.
Turn on the Chord Memory feature, by pressing the CHORD
1
MEMORY button so it lights—the CHORD MEMORY screen
appears.
Chord Set
parameter
There are three parameters on this screen you can use for getting just
the chord form you want. The first parameter allows you to select the
"chord set" that the Chord Memory feature is to use.
See Page 125 in the Owner's Manual lists the chords each key plays in
the factory chord sets. (The chart shows the chords for the key of C.)
Adjust the Chord Set parameter to try out different sets as you
2
play some keys on the keyboard and listen to the chords each one
contains.
Set the KEY parameter to select the actual key of your song. Each set's
3
chords are automatically transposed into the key you select.
The Roll Type parameter is what makes CHORD MEMORY so useful for
4
playing guitar sounds. By default, it's set to UP, which means that the
notes in the chord are played as a quick glissando from the lowest key
to the highest, like a standard guitar strum. You can also select
so they go in the opposite direction,
between upward and downward glisses, and
notes in a chord to be played at the same time, with no roll.
