Hi everyone - I am new to this group because I love my Matrix12 and
am desperately trying to find someone to repair it. Many of the
people on the web who say they repair Matrix12/Xpander do not
respond to emails - either business is good or they have given up!

Basically, oscillators/filters/VCA 1-6 all fail the autotune
function, suggesting a major problem. If anyone knows of a good and
reliable shop that can check out a Matrix12, I would be forever
grateful.
