TabView

TabView makes it possible to view and print PowerTab tablatures with your Mac.
PowerTab is a well-known and widely adopted tablature editor for Windows systems and thousands of transcriptions in this format are available on the net.

TabView is thus an essential tool for guitar players wishing to learn new songs as well for trainers.
TabView can export tablatures in MIDI format for playback or use in other applications (for instance, GarageBand).
While you're practicing a song, you can follow the playback on screen, loop over selected parts or slow the tempo down.
Create beautiful prints of the tablature: you don't need to stay in front of your monitor to play along your favorite song.
View both the standard notation and tablature, only the tablature or only the standard notation: whatever you prefer, it's possible!
NOTE: TabView is not an editor. If you need to edit or create tabs, you might want to look at Tablatures, http://itunes.apple.com/us/app/tablatures/id412028643
