Each accumulator has a reverse switch .
These are just another on/off value, like the gate, tie or skip values in a pattern.
When an accumulator is cleared its reverse switch is also turned off , so they normally have no effect.
But if you configure the limit behaviour to either “ rvtz” or “ rvbp” , when the accumulator reaches its
limit, the reverse switch is inverted – that is, if the switch is off, it is turned on; or if it is on, it is turned
off.
The effect of turning on the reverse switch is that any relative offset to the accumulator is subtracted
from the accumulator value, rather than added to it. - the effect of a relative offset is reversed .
Let’s look at what this does to the example pattern.
You have a four note arpeggio, with “offset note rel” assigned to aux A.
Aux A is adding 12 to the note accumulator every time step 1 is passed.
With the default accumulator config, the note accumulator rises to 36 (3 octaves up), then is reset to
zero .
To change the limit behaviour , press the soft-key below it on the display – F1 .
Each press of F1 advances to the next option, so if you press F1 twice, it will step from rtz to clip to
rvtz .
Once “ rvtz ” is shown in the display, press the “ OK ” soft-key, F3 .

When the offset event on the step shown in bold attempts to push the accumulator beyond its limit, the
reverse switch is turned on, and the offset value is subtracted from the accumulator.
The notes start shifting downward by an octave each time.
This will continue until the accumulator value reaches zero .
With the limit behaviour set to reverse to zero, when an offset event attempts to move the
accumulator below zero, the reverse switch is turned off , and the accumulator starts to rise again.
