I thought you could do this directly in Rosegarden, but then I tried
it with no luck.

Instead of using the matrix (piano roll) editor, open the segment
(region) with the Event List Editor. There's a toolbar button for
"Filter Selection" (it looks like a funnel filled with oil to me!). It
allows to select set up some criteria based on pitch, velocity, or
duration.

However, I can't really figure out how event editing is supposed to
work. If I select 2 events, right-click, and try to edit them, it
only edits the last event selected. The Filter just seems to
de-select everything I've selected, so I'm not sure what that's
supposed to do either. :(

I didn't try reading the manual, but maybe there's a way to make it work?
