Roland Jupiter-Xm Reference Manual

The I-Arpeggio function analyzes your keyboard playing and produces an optimal arpeggio pattern. You can select a type and rhythm to perform
extemporaneously, or use the step edit function to create user patterns.
Parameters such as the type and rhythm can be specied for each scene (ARP COMMON EDIT), and you can also specify for each part whether it will play an
arpeggio (ARP PART EDIT).

Performance detection
1. In the ARP PART EDIT screen, set “Switch” to “On” for the
part(s) that you want to play an arpeggio.
If “Switch” is set to “O ,” the part produces sound according to your
keyboard playing.
& “Part Edit” (p. 24)
2. Press the I-ARPEGGIO [ON/OFF] button to enable arpeggio
performance.
3. Use the I-ARPEGGIO [TYPE] [RHYTHM] [TEMPO] knobs to
specify the arpeggio pattern and tempo.
4. Play the keyboard to generate an arpeggio.
If you press the [HOLD] button to enable it, the arpeggio continues
playing even after you take your hand o the keyboard.
Selecting the arpeggio type
(TYPE)
You can change the arpeggio settings for parts 1–4. Depending on the
type, only one part might sound, or multiple parts might sound as an
ensemble.
Select the type that is closest to the arpeggio that you have in mind,
and then edit the sounds and parameters to bring it closer to your
preferences.
* With the factory settings, changing the type causes parts whose KeySw is “OFF”
to be assigned a suitable sound (TONE) and volume (PART LEVEL). If you want
to change only the phrase while preserving the current sound settings, set the
system parameter Arpeggio Set Tone to OFF.
Selecting the rhythm type
(RHYTHM)
You can change the phrase that is played by part 5, which is the rhythm
part.
Select a rhythm that is closest to what you have in mind, and then edit
the tempo, drum kit, and the various parameters to bring it closer to
your preferences.
* With the factory settings, changing the rhythm causes a suitable tempo
(TEMPO), sound (DRUM KIT) and volume (PART LEVEL) to be specied. If you
want to change only the phrase while preserving the current tempo and sound
settings, set the SYSTEM parameters Arpeggio Set Tempo and Arpeggio Set
Drumkit respectively OFF.
Specifying the arpeggio tempo
(TEMPO)
You can specify the tempo of the arpeggio. Depending on the sound,
LFO or DELAY can also synchronize to the tempo.
Adjusting the amount of shue
(SHUFFLE)
By varying the timing at which notes are sounded, you can create a
shue rhythm.
When this setting is in the center position, notes are sounded at equal
spacing. Increasing the value adds a shue feel like a dotted-note
rhythm.
Changing the duration of the notes
(DURATION)
You can specify the length during which each of the arpeggiated
notes is heard. Shortening the duration produces a staccato feel, and
lengthening the duration produces a tenuto feel.
