Music Memos App
Apple have introduced Music Memos, an App that lets you capture your song ideas. Basically what the app allows you to do is record high-quality, uncompressed audio through the built-in mic in your iPhone, a simple, clean way to keep track of your song ideas whenever inspiration strikes. Record acoustic guitar, piano, voice, or any musical instrument, the app then automatically analyzes the basic arrangement and suggests chords you played for each track. You can even hear how your music sounds with a realistic virtual drummer and bass player jamming along. Name, tag and rate your ideas to start building a library of all your favorite new song parts and riffs. All work can then be bounced to GarageBand or Logic Pro to continue building your song.
