Shift Amount
You can tell the Arpeggiator to transpose all of the currently latched notes each time it plays
through them. Shift determines how much transposition will occur for each cycle of notes. For
example, if you have latched C4 and F4, and you assign a Note Shift of 2, the Arpeggiator will
play C4, F4, D4, G4, E4, A4, and so on until it reaches the Limit value. The Shift values can range
from ‐88 to 88, with 0 (the default) being no transposition.
Shift Limit
Limit determines how far up or down the Arpeggiator shifts from the original note. The
minimum value is 0, and the maximum is 60. When the Arpeggiator reaches the limit, the
Arpeggiator responds according to the setting for the Limit Option parameter.
Limit Option
This parameter determines what the Arpeggiator does when it has shifted the currently latched
notes up (or down) to the shift limit. 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 latched
cycle of notes, transposing each cycle according to the settings for Note Shift and Shift Limit. If
the limit allows the notes to go out of MIDI range (for example, if you set Shift to 12, set the limit
to 60, and play C6), then those "ghost" notes don't sound, but they take up rhythmic space: the
Arpeggiator waits for the cycle to play itself out before starting over.
Unipolar means that after playing up to the shift limit, the Arpeggiator begins shifting notes in
the opposite direction, until it reaches the original pitch, where it reverses again. To determine
the next note when it reaches the shift limit, the Arpeggiator calculates the interval between the
shift limit and what the next note would be if the shift limit weren't there. It then plays the note
that is the calculated interval lower than the last note before the shift limit. The same thing
happens in reverse when the arpeggiated notes get back down to the original pitch. The
following table makes this easier to visualize by showing the result of arpeggiating one note
(C4) in Unipolar mode, with Note Shift set to 3 ST and various values for Shift Limit.

Bipolar starts out the same way as Unipolar, but during downward note shifting, it continues
past the original pitch until it hits the shift limit in the opposite direction, where it reverses again.

Same notes play in both directions

Note Shift
Last upward note before shift limit
is F#4, next upward note would be

A4, which is 2 ST from shift limit
D 4, ...
(G4); therefore first downward note
is E4 (2 ST below last upward note)
A4 is 1 ST from shift limit, therefore

first downward note is F4 (1 ST
