It was one of the headline acts when the iPad 2 launched back in March, but now, some months later, GarageBand has finally made it to the iPhone and iPod touch too.'GarageBand on iPad has been a big hit and we think customers will love using it on their iPhone or iPod touch,' said Philip Schiller, Apple’s senior VP of worldwide product marketing. 'The innovative multi-touch interface combined with Smart Instruments makes it easy to create great sounding music, even if you’ve never studied music or played an instrument before.'Yes, that's the beauty of it. You don't need any musical training, just an ear for a tune and a bit of time to understand what everything does within the app. You can play and record keyboards, guitars, drums and basses in a wide variety of styles, while Smart Instruments now allow you to choose from an extensive new library of custom chords so you can play and strum along with your favourite songs.If that's not enough, you can plug your electric guitar into your iPad, iPhone or iPod touch to play and record through 'classic amps and stompbox effects', or record your voice or any acoustic sound using the built-in microphone. With GarageBand, you can record and mix up to eight tracks and then share your finished song with friends or send it to your Mac to keep working on it in GarageBand or Logic Pro.Cherry on the top? If you are an Apple device lover and you already have an iPad 2, the update is free for your iPhone or iPod touch. However, if you are new to GarageBand, you'll be paying £2.99. GarageBand runs on the iPhone 3GS, iPhone 4, iPhone 4S and iPod touch (third and fourth generation).
