I don't use PT so I can't help, but I'll mention that there are a number of converters that show up in Google. I remember when this was impossible not long ago, and then when it sort-of worked but only on the purest of monaural single sounds. Melodyne that Noel mentioned is the gold standard now.

One other thing. I know you asked about PT, but in BIAB, if a RealTrack has an underscore in the track name in the radio button, it means that MIDI notation is provided. While this doesn't play, it can be copied to a DAW and assigned a synth and it will approximate the performance, though without the actual player's nuances. In the case of piano, it's quite accurate. Other instruments like electric guitar or sax, less so.

And welcome to the forum, Bill.
