FCBFF works with the Behringer FCB1010, using the stock firmware (the app does NOT support mod chips such as Uno). Programming the FCB1010 can be a nightmare; we wrote the app to make the whole process less painful. The app can work in side-by-side and slide-over mode on an iPad, making it easy to configure your iOS synths. Once you've got the configuration sorted out, download the settings to the FCB1010 -- or you can use the app as an FCB1010 emulator. The app supports conventional iOS QWERTY keyboards; this allows you to use the app like a wireless FCB1010, and you don't have to lug the beast around at all times. Here's a short video showing you how to set things up, and what the app does.
