Saving to other formats allow you to use different software to process them. For example, because Melodyne doesn't work properly with PTPA or RealBand clocking, I will take a vocal I recorded in RealBand (essentially the same as doing it in PTPA) and save it out to a WAV file, do pitch correction in Melodyne, and then import it back in to RealBand.

Not so much for MIDI tracks (since they don't take up as much room), but I will also sometimes save off audio tracks to WAV (perhaps multiple takes) that I'm not necessarily using on the project at this time, but don't want to lose later. That keeps the .SEQ file smaller, but still makes those files available to me to import back in if I want to. Sometimes I decide I might want a remove recorded part from the project, but later change my mind and add it back in.

Likewise, I might record a MIDI part in RealBand using my keyboard. I can then export it out to a .MID file, which I can use to create notation in my preferred notation program.

Having the options allows for great flexibility.

That being said, most other DAW's also have their own proprietary "project" format to save everything you do as a "project", but they also allow exporting and importing of the individual file types.

Hope that made sense.
