iShred update

iShred has been updated. Here's what's new:

• Alternate tunings can now be created and saved in a song. Great for Drop-D and other special tunings, or just for key transposition.
• Can now adjust the guitar's volume independent of any backing track or music player volume, making it softer or louder than before.
• Strings are now animated on faster devices (including iPhone 3GS+, iPod touch 2nd gen+, and iPad).
• Fixed bug that reset the HK-2000's delay to 2000msec.
• Version number now shown in the Settings/About title, not on the splash screen.
