It certainly is a shame that the Audya 4 seems to be causing problems for, at least, some customers. I suppose the newer 76's may have some problems, but it doesn't seem nearly as bad.

I don't pretend to say what Ketron has not done correctly, except perhaps releasing units before thoroughly testing them.

The real shame,IMO, is the fact that a bug free Audya is one great keyboard that I enjoy immensely.
