matrixcols gets reset to 1
matrixcolnames do not stick beyond the first name
See also the help patcher of mubu.concat~ in the basic tab.
LoudnessMax is renamed to 1 and the data does not reflect the loudness
somehow the number 2 for matrixcols seems to stick, so maybe I am missing something that is important to know…
