Shift Limit

Sets the maximum number of semitones that arpeggiated notes can be transposed up or down.
This parameter is relevant only when Note Shift has a non-zero value. When the transposition
reaches the shift limit, it changes direction according to the value for the Limit Opt parameter.

Limit Option (Limit Opt)

Determines what the arpeggiator does when it has shifted the currently latched notes up (or
down) to the shift limit. there are seven possible values:
Stop
Causes the Arpeggiator to stop the arpeggiation 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 80, and play
C4), 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
After transposing 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 (if reversing from upward transposition) than the last note before the shift limit.
The same thing happens in reverse when the arpeggiated notes get back 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.

Comment
Same notes play in both directions
when Shift Limit is a multiple of Note
Shift
Last upward note before shift limit is
F#4, next upward note would be A4,
which is 2 ST from shift limit (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 lower than
last upward note)
All symmetrical again; now A4 is within
shift limit
Next upward note would be C5, which
is 2 ST from shift limit
C5 is 1 ST from shift limit
Symmetrical again, including C5
