Singing range identification apps

I like the singing range and pitch shifting features of the "simply sing" app but you are locked into terms they use and the limited library of songs they have.

I would like to have my specific range expressed in musical terms eg "from G2 to G4" I could use outside the app (it just talks in general classification)

I wondered if there were any other apps or Windows/Linux programs that can do that (I am a subscriber and did suggest it but got no answer)

It would also be useful to know how to explain how you would like a song pitch-shifted in general terms for karaoke ("down two steps please") or musically (for a someone playing a instrument).

Finally is there a midi player (or whatever) that can do pitch shift so I can do other songs?
