Software for manipulating MIDI files

I need to do simple manipulations to MIDI files, such as making them play faster or slower, and cutting & pasting. Do the dopers have any suggestions?

I used to use Anvil Studio. It was free. It was also kind of crap and making songs on it was like trying to type with your chin but if you just want to edit stuff it should be okay. There are also some other free midi programs but I’ve never used them. Just search for “free midi program” or something. Sorry if this isn’t very helpful, I really hate this keyboard and you know how that is. Hopefully.

Quartz AudioMaster is what I use, and it’s great and free.
