All of the updates from the past 6 or 7 months have a copy-paste bug that behaves erratically when copying MIDI data from one track to another track. I think the last version that does not have this crucial flaw was released around April, 2016, version 22.7, I think.
Copying and pasting are essential, core operations regardless of how one uses a DAW. I hope this bug receives the highest priority. In fact, wouldn't it be great if Cakewalk devoted one entire release to nothing but bug fixes...
