That's right. 'abs' seems to be somewhat redundant - but there are uses
for it I'll spare you the details of until you get a hang of the basics
;-)
Once the value in an accumulator is set, it will be added to it's
associated value in all following steps.
So on every step (where X is not set, and ignoring result wrap/clip):

transmitted note number = force to scale ( step note number + part Xpos
+ playlist step xpos + note accumulator )

transmitted velocity = step velocity + velocity accumulator

transmitted aux D value = step aux D value + aux D accumulator

Note that if you have aux D set to an aux event rather than a midi
controller, the accumulator will modify the operand of that event. So
for example, you might grab notes from other tracks with aux D, using
aux C to sweep aux D back and forth across the other tracks by
offsetting the aux D accumulator. While simultaneously arpeggiating the
result with the note accumulator. And sweeping the filter like a clock
synced LFO using the velocity accumulator.
