This setting is provided so you can continue to use aux D for controllers or other events, while using
the aux D accumulator for the “ Accumulator Mask ” events.
Auxiliary Value Scaling
You may notice when you use the aux D accumulator to change the values of aux events that
sometimes adding an offset of 1 seems to have no effect on the event assigned to aux D.
This can happen because the accumulator values used by events, where the event has a smaller range
of values than the maximum possible for an aux, are scaled down.
For example, the event “ xpose by trk n ” takes a value from 1 to 8.
If this event were assigned to aux D, and the accumulator used to offset the event value, the full range
of the accumulator – 0 to 127, will be scaled across the range of the event – 1 to 8.
So in order to offset by 1 track for the xpose … event, you must offset the accumulator by 16.
The range of 128 accumulator values divided by the 8 possible track values gives 16 steps per value.
By scaling events in this way, you can use the accumulator to make very gradual changes to events
with reduced value ranges.
