How to Use Music Memos

1 Make a recording Open the app and either connect a special iOS-compatible microphone or use the mic built in to your device. Tap the Record button or tap Auto, which records when sound is detected. Play your instrument or sing your melody.

2 Check the results Tap the Stop button, then play back the idea. Tap the waveform for a detailed view, and drag the blue playhead around the recording. Use the Trim tool (below the play button) to get rid of dead time at the start or end.

3 Correct any mistakes If the app has mistaken any chords, tap the Chord button (Cm7), then any segment, and then the correct chord below. This also applies to changing speed using the Tempo button. You can return to do this later, if necessary.

4 Add some drums Hold a finger on the drums icon to open the rhythm section. To the left of the X/Y pad, pick a modern or a vintage kit, and pick a drum type on the right. During playback, move the dot on the pad to alter volume and complexity.

5 Add some bass Hold a finger on the bass icon and do the same for that part; you can choose from two instruments, and alter volume and complexity. Using headphones can help, since iOS devices’ speakers don’t always do bass brilliantly.

6 Share the track When you’re happy with the results, tap the Share icon to upload your idea to iCloud, send it to iTunes to develop in GarageBand on your Mac, or to that app’s iOS version. You can upload to Soundcloud if its free app is installed.
