ive come across an issue with the mod kit for the vss 30. a few
of the keys, when pressed, issue a quite loud high pitched tone, and its
only been happening since i modded it. its only about three of the keys and
they all out put the same tone. i was wondering if you know why this could
be and how i could fix it? cheers
It's tough to say exactly what is causing the problem, but there's likely a short circuit somewhere in your installation. This is not an expected result of the UMR installation.
I would carefully double-check the connections between the VSS-30 and UMR and make sure there are no short circuits. You might also disconnect the wires one-at-a-time in order to find which one is causing the problem.
Hope this helps--please let me know your results.
