Arpache 5 and / or SX

thanks in advance for any help! I have watched a couple of videos on Arpache, and tried several things here is what I am trying to accomplish: use a chord track, have legato strings play those chords, use arpache for arpeggios from those chords, but have slight variations ex: cellos on quarter notes, violas on eighth notes, violins sixteenth notes.I am a rookie with Cubase 8 pro, it may be obvious how to do this, I just haven’t figured it out yet. Do I load another instrument track, and another instance of arpache to get these variations? Or copy the chords to a new instrument track? thank you.
