The iPB-10 allows you to create your ultimate pedalboard, all on your iPad. Design a pedalboard by simply dragging and dropping up to 10 different pedals, in any order, to each pedalboard. You can even add an amp and cabinet to each setup. With 87 different pedals, 54 amps, and 26 cabinets to choose from, your options are virtually unlimited. Simply swipe your finger across the iPad to rearrange your pedals, turn them on and off, or to adjust their knobs.
The iPB-Nexus app for the iPad gives you touchscreen control of your pedals, amps, and cabinets. Simply drag and drop your choice of 87 different pedals to your pedalboard. Select an amp and a cabinet to make your setup complete. Using the iPB-Nexus app to control your iPB-10, it’s never been easier to explore your tone and find just the right sound.
The iPB-Nexus app includes the My Tones library where you store, organize, and rate all your favorite presets. My Tones allows you to store an unlimited number of presets and group them any way you want. For example, you can make preset lists for certain sets or specific music genres. This makes setting up before a show a snap. With My Tones, you can have a different pedalboard for each gig, set, song, or even switch pedalboards within a song.

Digitech introduces programmable iPad pedalboard

With Digitech new iPB-10 Programmable Pedalboard, users actually slot Apple’s tablet into the built-in docking bay and then hook up the instrument and amp to the back of the unit itself.
"The iPB-10 will stream a digital audio signal to any application that uses the digital audio input on the iPad," Scott Klimt, Marketing Lead at Digitech, told Gizmag. "In our testing we’ve found that we can create a preset within iPB-Nexus app, run that sound into Garageband, and add any additional effects within that application and record tracks. We’re not able to control third party apps with the footswitches but you can run those apps while the iPad is docked in the iPB-10."
Digitech is also currently working with application developers to incorporate more features into the Nexus app and has plans to offer users the chance to upload custom presets to a community portal and share them with others.
