Tutorial: Mastering GarageBand for the iPad
It costs only $5.99, but GarageBand for the iPad is not only easy-to-use but has plenty of hidden depths. Here's a primer to what's possible with this iPad app.

GarageBand for the iPad is an extraordinary piece of software. For a mere $5.99, it offers a remarkable range of accessible musical tools for novices and experts alike. Although it has its shortcomings, it can help you develop musical ideas in a way that’s never before been so easy and enjoyable.

The beauty of GarageBand is its flexibility. If you just want to “doodle”, you can use the virtual keyboard to play melodies and chords on a wide selection of instruments, ranging from pianos and organs to classic analogue keyboards – complete with envelope and filter controls for tweaking the sound, just like on a real synthesiser. You can play percussion by tapping on a virtual drumkit, or play guitar chords and riffs with the Smart Guitar. You can work with loops, sample your own sounds, and even record live vocal and guitar lines. 

Yet GarageBand also includes a full sequencer, allowing you to progress from tinkering to assembling complex piecesof music, which you can divide into up to ten sections across eight tracks. Whether you’re looking for a musical sketchpad or a handheld workstation, we’ll show you some of our favourite techniques for making the most of this powerful app.

The Basics

GarageBand has considerable depth, so it’s worth familiarising yourself with the help documents built into the app to enable you to find your way around. Ironically, these help documents are themselves slightly hard to find: tap the question mark icon at the top right of the display and you’ll see only a few sticky notes indicating what certain buttons do.

To access the full help system, click the Tools icon (the spanner next to the question mark icon) and click the Help item from the menu that opens. This will give you an overview of creating, editing and sharing songs using GarageBand for the iPad.

The online help doesn’t cover everything, but it’s a good way to get to grips with the fundamentals, such as adding and removing Tracks and arranging sections to build up a complete song. You may find it more convenient to view the help file on your computer, so you can refer to it while you’re using the app: you can find an online mirror of it by clicking here.

Apple Loops

 

It’s easy to miss GarageBand’s built-in library of Apple Loops, as it’s hidden behind a cryptic icon. This is a shame, since loops are a great way to get started on a new composition – or to add atmosphere to existing work. The selection isn’t as extensive as the library you get with the Mac version, but it still offers a wide palette of ready-to-use musical components. 

One common use for loops is providing a drum track, over which you can layer your other instruments. Click the Apple Loop icon at the top right of the Track view and you’ll see a window showing a list of 85 drum loops. You can scroll through it and tap to hear a preview of each one. When you find one you like, drag it out into the track area: GarageBand will automatically create a track for it, and set it to play for the length of the current song section. 

Many loops come in multiple variations, such as alternate rhythms and fills that can add variety to your song. To insert a drum fill or variation into your loop track, you first need to create a space for it. To do this, double tap on the drum clip that’s currently there; select Split from the contextual menu that appears; then drag the split marker to the point where you want to insert your new clip. Drag the marker down to make the split, then repeat the process at the point where you want to return to the original clip (typically, the start of the next bar). You can now double-tap on the middle clip you’ve just created and delete it, then drag an Apple Loop into the empty space.

Loops aren’t limited to drum beats: click the Instrument item in the Apple Loops dropdown and you can also choose from a selection of musical loops including basslines, tambourines and even a few backing vocal lines. These musical loops are automatically pitched to match the key of your song, which you can select from the Song Settings dropdown at the top right of the screen. 

You can also import additional audio files into GarageBand compositions, in AIFF, WAV, CAF and Apple Loop formats. The files must previously have been transferred to GarageBand from a PC or Mac using iTunes’ file-sharing feature. To import them, go to the Track view, tap in an empty track, then tap the “Import…” button that pops up to see a selection of available files. 

Smart Drums

 

If drum loops don’t inspire you, GarageBand’s Smart Drums are an easy way to create your own groove. To make a basic drum beat, drag the Kick drum, Snare drum and Hi-Hat cymbals icons from the right of the screen onto the grid, placing them near the middle of the top row. If you’re not sure what each element does, tap the “power” icon at the bottom left of the display, then drag the elements onto the grid one by one to hear how they contribute to the beat. Drag each element to the left to make it play a simpler rhythm, or to the right to make it more complex. Move it down the grid to make it play more quietly. 

Depending on which drum kit or machine you’re using, you’ll see a selection of other percussion instruments, too, which you can drag onto the grid to add interest. When you have a beat you’re happy with, hit Record to lay it down. To create extra variety in your drum track, you can move icons around while recording – or stop, move the icons about, then resume the recording. If inspiration still doesn’t strike, tap the die icon near the bottom-left corner to create a random beat, which you can then tweak to your liking; use as is, or play over the top of a loop to create a new combination of rhythms.

Smart Chords

 

The Smart Keyboard, Bass and Guitar instruments are a great tool for creating chord progressions. If you’re a musical novice that may sound daunting, but GarageBand keeps it simple by offering only a selection of common chords for whichever key your song is in (C major, by default), and you can experiment to your heart’s content.

The Smart Guitar instrument is a good one to experiment with by tapping the lettered tabs that sit above the virtual “strings”. Try playing C – which is the root chord of your key – then F, then C again. Then, for comparison, try playing C-G-C to hear how these chords work together. Tap the strings beneath the chord names to play individual notes from each chord. 

Once you’ve got the hang of this, try working in the minor chords at the left of the screen: Em, Am and Dm are the relative minor chords of G, C and F respectively, and you may be able to hear the relationship between them. The two chords at the right-hand side – Bb and Bdim – don’t fit so easily with the others, but they’re useful in certain contexts. Switch on Autoplay and you’ll hear your virtual guitar play a simple riff (there are four to choose from), which follows the chords you press. If you turn off Autoplay, you can drop in your own notes by strumming or tapping the virtual strings. 

The big limitation of Smart Chords is that there’s no way to play chords outside of the eight on offer. If you want to create more complex chord progressions, or to change key during the course of a song, you’ll have to play the unsupported chords “by hand”. If you’re using the Smart Guitar or Bass, you can do this by switching your Smart instrument to Notes mode, and using GarageBand’s multitouch support to play the appropriate notes to make up the desired chords. If you’re using the Smart Keyboard, switch to the regular Keyboard. Alternatively, you could hook up an external instrument.

Connecting Instruments

GarageBand includes everything you need to create and record music, but you can hook up other instruments to it as well – with the aid of some extra interface hardware. 

For example, you might want to connect a standard MIDI controller keyboard, for playing GarageBand’s virtual piano and synthesisers. This gives several benefits over the built-in virtual keyboard. For one, full-sized, physical keys are easier to play. What’s more, a dedicated keyboard will give you better touch sensitivity. The GarageBand virtual keyboard tries to detect how hard you’re hitting the keys using the built-in accelerometer, but notes occasionally come out more loudly or quietly than intended. Without an external keyboard, the only way around this problem is to click on the Keyboard icon at the right of the screen and disable velocity sensing altogether. 

Attaching a MIDI keyboard is simple. Most USB MIDI interfaces will work with the iPad, so long as they’re “class-compliant” and don’t require special drivers. In order to equip your iPad with a USB port, you’ll also need Apple’s Camera Connection Kit. This costs $35 from Apple’s online store, and a suitable MIDI interface can be found online for about $30. 

If you want to record vocals or a real instrument, you can use the iPad’s built-in microphone. The recording quality is surprisingly good, especially if you take advantage of GarageBand’s noise gate, which cuts out quiet background noise so that you don’t get hiss or hum when you’re not singing or playing. Getting the volume levels as you want them will require some experimentation, however, and positioning the iPad to get a good recording can be difficult: it’s more convenient to use a dedicated interface. 

One such interface is the IK Multimedia iRig, available for around $60. Designed for electric guitar players, it’s a simple pre-amp that boosts your guitar signal to a level suitable for your iPad’s headphone/microphone socket. Those seeking the very best in quality can invest in the Apogee Jam ($119 from the Apple Store), which provides a digital connection to the iPad. 

With an interface like this, you can play and record through GarageBand’s selection of 32 simulated classic amplifiers – some of which sound impressively authentic – and patch in up to three virtual effects pedals. Be warned that, unlike Apple Loops, parts recorded in this way won’t be transposed if you change key – make sure you’re happy with the key before recording, or you could have to re-record it.

Exporting to a Mac

GarageBand for the iPad is a great way to assemble rough and ready musical ideas. If you want to perfect your creations, however, you may find yourself hankering for better editing tools and more audio-processing effects – and you may want to expand beyond the eight tracks available on the iPad. 

If you’re using a PC, this isn’t an option. If you’re on a Mac, however, you can export your creations to the desktop version of GarageBand and continue working on them there. This requires a recent version of GarageBand for the Mac, so you may need to run Software Update. 

Exporting your files to the Mac is easy. Go to the My Songs view in GarageBand for the iPad, then click the Share icon (the leftmost one at the bottom of the display) and tap “Send to iTunes”. The next time you sync your iPad, the file will be available for transfer. To find it, click on the Apps tab in iTunes, scroll down to the File Sharing pane and click GarageBand. You’ll see your song appear in the pane to the right. Click “Save to…” to copy the file to your Mac.

You can now open and edit your project in GarageBand for the Mac, but be aware that it’s a one-way trip. With the current versions of the software, there’s no way to bring your song back onto the iPad once you’ve edited and re-saved it on a Mac. You should therefore only take your projects onto the Mac once you’ve done everything you want to on the iPad.

Editing Clips in GarageBand

A popular way to get started with music software is to bash out a basic tune using an instrument such as GarageBand’s virtual piano, then open up a piano-roll view and correct any mistakes by dragging misplaced notes into the right positions. This is how almost all music software works: in GarageBand for the Mac, for example, you double-click on a clip in the Track view to see the piano roll pop up at the bottom. 

On the iPad, however, there’s no piano roll. If you make a mistake, there’s little you can do. If it’s a timing error, the quantisation feature might be able to save the day (you’ll find it under the Settings dropdown at the top right of the Instrument view); otherwise, you’ll have to go back and record it again. 

It’s a pain, but things aren’t quite as bad as they sound. So long as you have a spare track, you can keep the good portions of your clips and only re-record the phrases containing mistakes. For example, let’s say you screw up the fourth bar. The first thing to do is cut out the offending section. To do this, go to the Track view, then double-tap on the clip you’ve just recorded. You’ll see a row of actions appear. Select Split, drag the split marker to the start of the fourth bar, then drag it downwards to split the clip. Repeat to make a split at the start of bar five, then double-tap the middle clip and select Delete. 

Next, it’s a simple case of re-recording the relevant section – but don’t try to record it to the same track as the rest, or GarageBand will overwrite the good parts of the recording you wanted to keep. Instead, create a new track using the same instrument, and use this to re-record the relevant section. Once you’ve got a good take, you can go back to the Track view, slot your recording into the gap in the original track and delete the now-spare recording track.
