The Arpeggiator (ARP) Page
Limit Option
This parameter determines what the Arpeggiator does when it has shifted the currently
arpeggiated notes up (or down) to the value set by the Shift Limit parameter.
Stop causes the Arpeggiator to stop when it reaches the shift limit.
Reset causes the Arpeggiator to return to its original pitch and repeat the cycle of notes.
Unipolar means that after a note reaches the shift limit, the note is shifted in the opposite
direction, until it reaches the original pitch, where it reverses direction again. If Shift Amount
is set to a positive value, a note will never be shifted below it's original pitch. If Shift Amount
is set to a negative value, a note will never be shifted above it's original pitch.
Bipolar means that after a note reaches the shift limit, the note is shifted in the opposite
direction, until it reaches the shift limit in the opposite direction, where it reverses again.
FloatRst (float reset) means that when the Arpeggiator reaches the shift limit, it looks at the
first note that would exceed the shift limit, and calculates the interval between that note and
the shift limit. It then restarts the cycle of latched notes, transposing the entire cycle by the
interval it just calculated, then shifting each subsequent cycle by the value of Shift Amount,
until it reaches the shift limit again.
Here's a very simple example. Suppose that the only note in the Arpeggiator cycle is C4,
Shift Amount is 4 (a third), and Shift Limit is 7 (so notes won't get shifted above G4). The
4, but that's above the shift
Arpeggiator plays C4, then E4. The next note should be G
#
limit—so the Arpeggiator calculates the difference between that G 4 and the shift limit (G4):
#
one semitone. It adds that difference to the original starting note (C4) and plays that note
next—C 4. The next note (F4) is within the shift limit, but the next note (A4) isn't, so it gets
#
translated into D4—and so on.
FloatUnip uses the same concept as FloatRst and applies it to Unipolar mode: when the
Arpeggiator reaches the shift limit, it calculates the difference between the next note and
the limit, and transposes the next cycle of notes down by that interval, then shifts each
subsequent cycle down until it reaches the original pitch.
FloatBip is similar to FloatUnip, but the downward shift limit isn't the original pitch, it's the
negative of the Shift Limit value.
Key Range (Low Key and High Key)
The Arpeggiator processes notes within the range of these parameters. Notes outside the
specified range play normally, and do not become part of the arpeggiation sequence. When
the Low Key or High Key parameter is selected, you can easily set the value by holding the
ENTER button and striking the desired key. Key Range is not saved with each Arp Preset,
but instead is saved as part of each program (or Multi Zone). This allows you to try different
presets while maintaining the same Key Range.
