Limit Option
is 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 (oat reset) means that when the Arpeggiator reaches the shift limit, it looks at the
rst 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). e
Arpeggiator plays C4, then E4. e next note should be G
#
4, but that’s above the shift
limit—so the Arpeggiator calculates the dierence between that G
#
4 and the shift limit (G4):
one semitone. It adds that dierence to the original starting note (C4) and plays that note
next—C
#
4. e 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 dierence 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)
e Arpeggiator processes notes within the range of these parameters. Notes outside the
specied 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). is allows you to try dierent
presets while maintaining the same Key Range.
