The UnO chip is a "UnOfficial" eprom update for the Behringer FCB1010.
It has solved many errors and gives more functionalities like the stompbox-mode.
With the stompbox-mode it's possible to use the upper (or lower) row as stompboxes.
This means buttons 1-5 and bank up/down will do program change (and could also transmit 2 CC's like tap tempo) and the upper row will control seperate FX's like chorus, delay, drive... of your MIDI-device.
Most recent version: UnO 1.0.2.f
