Has anyone tried Riffstation PC or Mac Trial and try the RiffBuilder on some of your realtracks, it picks up most of the RT tempos.
You can just drag a track out of BB\RB into RiffStation and you have the notation RealChart, just look at the time in the bottom of RiffStaion RiffBuilder to the time in the notation window in BB/RB of the RealChart to find notes/tabs.piano roll or just by ear. You can also drag the track in from the RealTracks folders.
If you have a problem with RiffStaion tempo just save a stereo render with the RT panned to the left and a click track (write Metronome to Track) panned to the right then RiffStaion will pick up the tempo. RiffStation will save the riff to wav.
