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.
Flt Reset
Adds a bit of apparent randomness to the process. Flt stands for "Float," and it means that when
the arpeggiator reaches the shift limit, it resets—but not to its original pitch as with plain Reset.
Like Unipolar and Bipolar, 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 Note Shift, until it reaches the shift limit again.
Here's a very simple example. Suppose that the only note in the arpeggiator cycle is C 4, Note
Shift is 4 (a third), and Shift Limit is 7 (so notes won't get shifted above G 4). The arpeggiator
plays C 4, then E 4. The next note should be G
calculates the difference between that G
difference to the original starting note (C 4) and plays that note next—C
within the shift limit, but the next note (A 4) isn't, so it gets translated into D 4—and so on.
Flt Uni
Uses the same concept as Flt Reset 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.
Flt Bipl
Similar to Flt Uni, but the downward shift limit isn't the original pitch, it's the negative of the
Shift Limit value.
