I had that FCB1010 and hated how non-flexible it was from the programming perspective.
I had to create an abomination of a virtual pedalboard to workaround that. Post is here
Maybe with that UNO chip it is better, but in its original, non modded state it was hard to use with MDX for me.
And it is really heavy, same way as a full old effects processor, like GT-100 or like that, which is a lot for a thing that just sends some midi signals. It might be a huge downside if you have to carry this thing around.
From a bright side, you probably can use it as a self-defence weapon.
And UNO chip is something you have to buy separately, if your device is vanilla.
