When Apple redefined the telephone five years ago, few people saw that it could one day be part of a new wave of music technology. But since the advent of the App Store, it and the iPad have become exactly that, with dozens of synth, sequencer, and sampling options. (Before anyone accuses the blog of being a big Apple advert, let it be known that this author is a Windows Phone user - who despairs at the lack of good WP music apps and looks jealously at his iOS enabled studio partner's wealth of options in this field).

The Jazzmutant Lemur once retailed for £1,700; its iPad emulation now goes for a mere £35, and gives brings one of the most innovative controllers ever well within reach of the home user. 'Griid' and 'touchAble' are two specialist Ableton controllers, while Novation's new 'Automap for iPhone' allows you to remotely edit and control your synths and mixes. All of these (and plenty more) offer lots of opportunities for performance; you can move around the stage and still control the sound, you can break away from that 'one guy staring at a laptop' problem that afflicts so many electronic musicians, and you can re-assign your controllers in any way that suits you - until you find the optimum arrangement for your own setup. Indeed, the open-ended nature of most touch-screen tablets suggests that in future, these will become dominant in electronic performance - Native have already released an app for their performance tool Maschine.
And what about doing it the other way around - controlling an iPad synth with another device? Alesis have recently released an iPad dock; with audio, USB, MIDI (and even footswitch) connections, you can now record and control your iPad apps with a full keyboard, and send audio into the device.
On the subject of audio inputs, check out the Amplitube iRig. Designed as an amp simulator for guitar players, it can also take any audio signal (obviously) and run it through another app - such as Moog's Filtatron. The Apogee 'AMP' does a similar function. See where this leads? Your very own hardware send/return loop! You can now use any of those great effects, filters and sound-warpers on any of your sounds, and record them back into the computer. Or, if you're talking live, a handy effects unit to plug into the DJ mixer. Cheap and easy.

And if you really want to scare yourself, just spend the price of a beer on Garageband for iPad. It's not ideal for writing dance music, but it's so slick, packed with sounds and instruments, and designed to help the novice come up with something listenable, it's almost enough to make you wonder whether we'll all be made redundant soon by means of a 'musician' app. It's a seriously impressive program.
So all in all, portable music production has some way to go before it takes over completely. But if you're looking for a range of useful tools to help with inspiration, new sounds, or jotting down ideas while on the move, smartphones and tablets are now an essential part of a modern producer's arsenal. It's exciting to think what the next couple of years will bring.....
