I experienced this very problem when I upgraded my K3 to the new synthesizers. The problem would go away if I took out the new synthesizers and reinstalled the old ones. I contacted Wayne about this issue and finally narrowed it down to “key bounce”. I was using high quality keys such as Begali.
Apparently a software issue related to timings with the new synthesizers which has never been corrected. 73, Charles, K4ZRJ > On Jun 19, 2016, at 4:16 AM, IK4EWX <glcazz...@alice.it> wrote: > > I own a great K3S from a pair of months.
