GarageBand already had a long history on the Mac, letting people use intuitive controls and a huge library of instruments and prerecorded loops to create songs. But with the iOS version, Apple needed to come up with creative ways to record music using only a touch-screen interface, and we think the company did an amazing job. In the latest version, GarageBand now supports Audiobus, letting you use sounds and effects from other music apps and then recording them to GarageBand tracks.
As a general overview, the GarageBand app offers several Touch Instruments, guitar amps and effects, eight-track recording and mixing, and more than 250 loops to play with. You can export AAC files of your projects through e-mail or add them to iTunes.
Immediately upon launch, GarageBand makes it easy to get started creating a song. Simply choose an instrument and start playing around with GarageBand's many options. GarageBand offers instruments you can play in real time like their real-world counterparts, but you also have the option to play Smart Instruments that do most of the heavy lifting for you. Every instrument has its own specific theme, giving all of them their own feel as you play. Some instruments even have added controls such as effects boxes you can turn on and off to fine-tune your sound.
Using the smart keyboard, for example, lays out all your chords in the chosen key. This means that just about whatever you press will probably go together in a song. You can change the key by touching the wrench in the upper-right corner of the screen. Using a combination of bass notes on the bottom and chords at the top, it's easy to create a nice-sounding song, even if you have very little experience playing the piano.
