Amidio, maker of the Noise.io Pro synthesizer application, has released Star Guitar, its new guitar and voice recording application for the iPhone and iPod touch. Unlike other virtual guitar applications which rely on a simulation-style interface, with small strings to tap and strum, Star Guitar presents users with a pad of chord buttons, allowing them to play the instrument with their thumbs. Three guitars are offered, with more coming in updates, and users can play chords via the manual SmartStrumming mode or by relying on one the more than 13 rhythm patterns, each with A and B variations for chorus/verse. In addition, the app can be set to record the guitar alongside the user’s vocals, saving the files in the .WAV format, which can then be accessed via a built-in web server over Wi-Fi. A YouTube demo video is available for viewing. Star Guitar is available now from the App Store and sells for $4.
