Inspectedby39, Congrats of a getting this fun instrument. I know you can set multiple routs from one lfo in the mod matrix. I think I understand your LFO question however, as its the same deal on the P12. I don't believe the lfo routings (set by the lfo knobs themselves) appear displayed in the mod matrix. I wish I was by instrument to double check that statement. Anyway,,, my approach is that I just use up the 4 available lfo slots, then, if I still need more, I go to mod matrix and pick one of the 4 lfo sources closest to the speed I want and and simply add a second new destination.
The Pro2 has an arpeggiator?

Seriously though, I don't think I ever looked at that feature being too engrossed with the sequencer.
