BCR2000 is probably the best thing Behringer ever made. Is actually a great bit of kit, and highly programmable.
Be a smart move to bring it back; and if as programmable as before, well worth getting as a studio / live workhorse.
There is a button at the top with [ CTRL/ZAQ ] on it in yellow / grey. Based on that I’d assume that you can switch between operating modes; Controller or Zaquencer, rather then both at the same time, but what would I know?
Would be interesting if the Zaquencer kept running whilst switching to Controller mode… but that could get confusing; and if that was the case; then it would be better product design to ditch the option altogether; and just have a [ Shift | Function ] button, a toggle button with led for mode; and a [ Latch ] option instead.
