Buy it!

This is the only tool you will need to put you back in control of your practice time! Stop re-tuning your instrument to the track and pulling your hair out over light-speed passages. The best part? Tracks are stored in a list with your tuning preference and tempo adjustments. Tremendous utility for your practice routine!

Now, if only I could hear my instrument within the program so that I could work with headphones, my wife would like it much better too.
