Newbie to the forum.  Bought the Rack ES in ‘05 and have used it predominately as a tone generator for Band in a Box and working with midi files.  There are some awesome grooves in the arpeggiations of many voices.  Were these set up relative to each other?  In other words...there are some fine drum grooves...is there an index to sync them to other voices?  i.e. The bass needs to be in sync with the kick drum...is there a synergism in how the arps were set up relatively speaking?  Or are they all random?  Thx.  Peace and love.

Not clear on the question. All the Arps in the Motif-Rack ES reference the same clock so there is no issue with synchronizing them. The Data is given a name that hints at the genre it was created for, whether or not it goes along with another ARP is really up to how you use it.
