The one thing that you can really say about the iPad is that it took the possibilities of the touch screen into a much more manageable direction. Instead of just having a miniature icon of music storage and multi-media interface there is now a full size, which means that the creative applications may just multiply. Just ask Rana Sobhany.
Rana is taking the iPad into the legit music making mode. She utilizes standard DJ equipment and and plugs in her iPad as the audio source. Here she incorporates her laptop as a method for looping out the audio and recording with Logic, as well a standard Numark mixer that any tablist would recognize. In the iPad she incorporates iPhone applications to begin integrating mixing capabilities, all of which comes in hundreds of dollars less than even the most basic DJ equipment that would be comparable. Software like Looptastic HD, Sonosaurus Rex, and AC-7 Pro all come in as being useful for this, not to mention that you actually have the possibility for tapping in to an audio library that you have synced to the music section of your iPad. KORG itself, which will always be a stable of the electronica scene, has its own application that will allow for sampling and mixing in a digital interface that almost matches its physical equipment. For a $9.99 application that may jump over to $19.99 this is brilliant, but really only made useful by the size of the iPad's touch screen.
Now that the precedent has actually been set by Rana Sobhany the likelihood is that even more musicians will try to use this technology in the creation of new audio modes, and developers will likely line up behind them to cash in. The second generation of the iPad may bring this into even better focus, but no matter what you still need to double up to really keep the continuous mix alive.
