I have set up presets for my acoustic guitars and my electric guitars in Amplitube for IOS.
The BlueBoard makes switching presets and changing banks effortless for live use. It's small size and light weight make it easy to carry in a pocket on my guitar bag. The BlueBoard app makes it easy to connect and customize your setup. Plugging an expression pedal into the BlueBoard allows you to control selected
perimeters within a preset in real time.
There is a momentary delay when changing presents to compensate for and you have to change batteries at some point but those small complaints aside I am totally pleased with the BlueBoard.
I haven't explored this yet but the BlueBoard can be used with other bluetooth compatible applications
in the studio or elsewhere.
