These dates show when I sent the update to Apple; Apple typically releases to the public a week later.

Version 2.0.4, 7/24/15

Version 2.0, 1/24/11

- Rewrote the audio processing code to reduce latency and avoid volume issues.

- Adjusted the audio settings to play even if the device is muted.

- Corrected an error where audio could stop after using audio in another app, such as making a phone call or using Siri.

- Added a Settings window with options to send MIDI notes for each instrument. When selected, the app sends a MIDI note-on message for each part of the washboard or each attached instrument that you tap. You can enter custom note numbers for each instrument, or tap the Restore Defaults button to load a default set of note numbers. The app still plays audio when sending MIDI, but you can turn down your device volume to avoid hearing it. The Settings window only appears for devices running iOS 4.2 or later.
