Soulo’s karaoke machine made a huge splash last year as a major app-cessory. At CES 2012 they have introduced a new line of instruments as well as upgrade to the app itself. Drums, keyboard, guitar, and updated Soulo mic are the new instruments you can look forward to rocking out on, on your iPhone, iPad, or iPod Touch. The app includes enhanced audio and video recording features as well as new holiday-themed songs and backgrounds. Mobile karoke is easy as pie now.
