Excellent app. at a great price

I downloaded this app today and I think the developers did a GREAT job in reproducing the harmonica on an iPhone. The only suggestion I would ask the developers for future updates is to allow the user to change the key on the harmonica. This way you could have an entire set in one app. Whenever I try to play along with my favorite artists, I seem to be out of tune with their harmonica. SO having the option to change key or at least tune it would be great. Thats why I only gave it four out of five stars.
Thanks for the App!
