Saeed, The advanced filter, found via the Edit menu, is the tool to accomplish what you want. It's a little tricky to set up though, so take your time getting accustomed to it.

I'm wandering how I can delete a bunch of system objects in one selection. As you might have encountered, in midi files there may be lots of metronum marks. I want to delete them for not being printed. As they are too many, it takes too much time to delete. Is it possible to select all of them in one operation? Thanks in advance.
