Hi Uncle Mickey,



Actually i have experienced, in my macOS Sierra/Band in a Box, what you describe on the very odd/rare occasion but can not recall what i did to create what i call stutter effect.

And so, i find it best to hit " generate and play " button in the transport bar the first time i start a song/project and especially after i make any changes to that song. After that i just hit the play button in the transport bar or tap the space bar.

At the moment not exactly sure about your issues 2 and 3.

Will give them some more thought.
