Chris,
I will look at that Dance pack. Coincidentally I had bought the EasySounds Dreamscape pack a few weeks ago. Today, after you mentioned multi-pads, I opened this pack back up but did not see any arpeggio multi-pads in it. Their styles have nice arpeggios built into them, but no separate arpeggio multi-pads.
Are you saying Magic Dance has arpeggio multi-pads, and if so, do you know how many? Their packs are not cheap. I was a bit disappointed in the Dreamscapes pack. Many of the voices were too sound effecty and not as playable for my taste and the Styles to me were too similar to each other, but that is just my opinion. I would recommend the pack to anyone but perhaps not at the 73 dollar price.
