No. The effect processing is done inside the iStomp pedal using an AudioDNA™2 processor. You only connect your iOS device when you want to load a new pedal from the Stomp Shop to your iStomp
Just like every other stompbox. Simply turn the knob of the control you want to change until you get the right sound. The settings of the knobs are not changed using the iPhone, iPod, or iPad.
The iStomp comes with 9 pre-printed and 3 blanks removable adhesive labels. You can write on these labels to properly identify the knobs of the effect you have loaded into your iStomp. You can add and remove each label multiple times without any residue or adhesive sticking to the iStomp. The Stomp Shop App also has a description of each pedal, the knob mapping and input/output routing options in the information section of each pedal.
The DigiTech iStomp is an entirely new concept in pedals. It works just like a traditional stompbox with one huge exception. It can be completely reconfigured by loading it with any of the 28 (and growing) e-pedals available in the Stomp Shop app.
Unlike devices that require you to stay tethered to your iOS device, the iStomp does all of its processing internally. This means professional-quality, high-definition signal processing with no latency and you don’t need your iOS device while you’re playing.

The iStomp is the only stompbox that allows players to demo different e-pedals using their own rig before they buy it. Through the app you can listen to a demo of all the e-pedals but unlike all other stompboxes you load any e-pedal for upto 5 minutes to see how the it sounds through your amps using your guitar before paying anything. 
The Stomp Shop saves a record of all the e-pedals you purchase becoming your e-pedal virtual road case. You can now carry your entire e-pedal collection with you on your phone. From the Stomp Shop app you can reload any e-pedal to your iStomp at any time. 
You can choose one the color of the 9 dot LED light on their iStomp when you load an e-pedal from the Stomp Shop App e-pedal store and virtual road case. It is a great way to identify each e-pedal when it is loaded on your iStomp. 
The new DigiTech Smart Cable (DSC) is a proprietary cable developed by DigiTech in conjunction with Apple that allows direct communication between DigiTech products and iOS devices such as an iPod touch, iPhone, or iPad. The iStomp along with the Stomp Shop App are the first DigiTech products to incorporate the new DSC cable and DSC Port.
