GarageBand for Mac turns your Mac into a simple any time, anywhere recording studio. It's the easiest way to create, perform and record your own music on a Mac whether you're an accomplished player or just wish you were a rock star.

Key features:

• Record with any USB or MIDI keyboard, guitar or microphone.
• Mix your track using professional effects and settings.
• Use thousands of included pre-recorded loops to add "virtual musicians".
• Make your guitar sound like it's playing through your favorite vintage amp.

GarageBand for iPad, iPhone and iPod touch turns your iDevice into a collection of Touch Instruments and a full-featured recording studio — so you can make music anywhere you go. Use Multi-Touch gestures to play pianos, organs, guitars, drums, and basses on your iDevice. They sound and play like their counterparts, but let you do things you could never do on a real instrument.
