Shieeet, jumpstreams are definitely possible on pad, but it kind of depends on the pad you're using. There's also a specific technique involved. I think it's called the heel/toe technique or something of the sort. I've seen folks play jumpstream heavy files, full combo'ing and even AAAing them, and it looks like they barely even lift their feet off the pad.

Edit: Pretty much like TC_Halogen is describing.
