I'm not exactly answering your question but....
I have to go out on a limb here and defend arturia. just because 5 users complain over and over on the forums, it doesn't mean the machine is weak. the ratio of minibrutes sold vs users with issues has to be 500:1, at least. if this wasn't the case, arturia would be going out of business.
if you do run into an issue, chances are it's due to a loose cable, which you can service yourself with clear instructions from arturia tech support.
honestly, this is a wonderful machine that makes wonderful sounds, the price point is spot on, and the staff behind it are some of the coolest people on this planet. buy with confidence
