If "scne1" is selected and KbdMode is set to
"chrd&norm", you can play arpeggios with Scene
1 to the left of the Split Point, and play normally
with Scene 2 to the right.
Scene 1: Scene 2:
Bass sound Solo sound
Scene 1 only
Arpeggiator
If "scne2" is selected and KbdMode is set to
"chrd&norm", you can play arpeggios with Scene
2 and normal chords with Scene 1 to the left of the
Split Point, and play normally with Scene 2 to the
right.
Layer mode = SINGLE
If KbdMode is set to "chrd", you can play
arpeggios with the selected [SCENE] switch only
(or Scene Control sound) across the entire
keyboard.
If KbdMode is set to "chrd&norm", you can play
arpeggios with the sound of the selected [SCENE]
switch only (or Scene Control sound) to the left of
the Split Point and normal chords with the sound of
the selected [SCENE] switch only (or Scene Control
sound) to the right.
"both"
When the Scene Switch is set to "both", both Scenes
will play as follows:
Layer mode = DUAL
If KbdMode is set to "chrd", you can play
arpeggios with Scene 1 and Scene 2 across the
entire keyboard.
If KbdMode is set to "chrd&norm", you can play
arpeggios with Scene 1 and Scene 2 to the left of
the Split Point, and play normally with Scene 1 and
Scene 2 to the right.
Layer mode = SPLIT
If KbdMode is set to "chrd", you can play
arpeggios with Scene 1 to the left of the Split Point,
and play normally with Scene 2 to the right.
If KbdMode is set to "chrd&norm", you can play
arpeggios with Scene 1 to the left of the Split Point
and normal chords to the right.
When SceneSw "both" is set in SPLIT mode, depending on selected arpeggio
Type, as well as Split Point setting and the position at which you play the keys,
certain notes of the arpeggiated chords may cross the Split Point, i.e., lower notes
will play Scene 1 and higher notes will play Scene 2.
Layer mode = SINGLE
(Same as for "scne1" or "scne2", page 35.)
Arpeggio Pattern Length
The length of an AN1x arpeggio pattern is determined by
three factors which work together simultaneously: Arpeggio
Type, Arpeggio Subdivide setting, and the total number of
notes you play for an arpeggiated chord.
For example, say you play an arpeggiated pattern with a
four-note chord, such as a C major triad with an octave in
the root. If Subdivide is set to "1/8", the Arpeggiator breaks
down the chord into 8ths, and then arpeggiates it based on
the Type setting. If Type is set to "UpOct2" the arpeggio will
climb over two octaves, and will repeat after four beats.
Then, if you change Subdivide to "1/16", the arpeggio will
repeat after 2 beats. Furthermore, if you then change Type to
"UpOct1", the arpeggio will repeat after only one beat.
Because the number of notes you play in the chord has a
direct relationship on the pattern length based on Subdivide
resolution, sometimes unwanted syncopations may be
generated. As a general rule, you can avoid this by choosing
an even number of chord notes for even-numbered subdivide
resolutions (1/4, 1/8, 1/16 and 1/32) and an odd number
of notes (e.g., three-note or five-note chords) with odd-
numbered resolutions (1/6, 1/12, 1/24).
However, this doesn't apply for dotted note rhythms (3/8,
3/16 and 3/32). These resolutions are particularly
interesting for odd-numbered beats (e.g., 3/8 or 6/8), so
you will need to play chords with an even number of notes to
correctly play back these three-part rhythms.
As an example, set Type to "UpOct2" and Subdivide to
"3/8" resolution. Playing a triad will place the root note on
the first beat in the 4th bar, generating irregular cycles. A
four-note chord, however, generates symmetrical 4 bar
cycles. The root note will be repeated after the first cycle on
bar 3, after the second cycle on bar 5 and after the third
cycle on bar 7, and so on, always landing on the first beat.
In the case of the special Arpeggiator Types (16-30), you will
notice that these aren't particularly effective with triplet
rhythms. Best results are achieved with a 4/4 beat and a
Subdivide resolution of "1/16", "1/8" or "1/32".
