Harp for iPhone/iPod

When playing Harp, you may not wish to be interrupted by a phone call, alarm, or SMS. However, there is no way that Harp (or any iPhone application) can avoid these interruptions for you— you must do it yourself by deliberately silencing your iPhone or iPod. Here are the steps that Apple recommends:

1. In the Settings application, ensure that the iPhone has Airplane Mode turned on.
2. In the Calendar application, ensure that there are no event alarms enabled during the planned performance period.
3. In the Clock application, ensure that there are no clock alarms enabled during the planned performance period.
4. Do not move the Ringer/Silent switch during performance. When changing Ringer/Silent mode, an iPhone may vibrate, depending on user settings.
5. Lastly, do not plug the iPhone into a power source during performance. When an iPhone gets plugged into power, it beeps twice or vibrates, according to user settings.

Harp 1.0.1, which fixes a crackling sound experienced with Harp by 2nd-generation iPod Touch owners, is now available as a free upgrade.

Note: This problem only affects 2nd-generation iPod Touch owners. iPhone and 1st-generation iPod Touch owners are not affected.

Thanks for everyone’s helpful feedback on the crackling noise that appears when using Harp with the 2nd-generation iPod Touch. I’m sending version 1.0.1 of Harp off to the App Store today, so you should have the fix in your hands shortly. Thanks for your patience.
