Hi Folks , Has any one heard of our had experience of "ANATEK midi filters "

I've got a few stray midi signals from my digital Concerto midi accordion , it's always been a problem that has never been resolved 100% .
I'm unable to stop them from my Technics Kn7000 midi filter control .
I've been told from some one in the USA that a solution would be to use an ANATECK midi filter to block the offending signals from my accordion .

As always i would appreciate any help.

Best regards ............Giovanni
