my idea for the bluebox! adds a loop recoder to the master track. with the loop recorder you can then record the sum with one time signature. e.g. 1/4, 1/2 or 1 to 4 bar. With a connected midi controller (faderfox with crossfader, for example) you can then thread into the recorded loop and load the next setting on the devices. Maybe you can still save the recorded loops automatically and then continue to use them during the live act or load them into the bitbox. that would be great and you would have a small dynamic recorder like the octatrack.
