Ah! I think I know what you mean!
When I jog on the Control… It tends to be jumpy and less precise, especially when zoomed in tight! It seems as if it is sending the commands at a lower resolution!
I also have an Artist Transport, which doesn’t do that… It is completely smooth (higher resolution) when I jog, and is also very precise.
I tried the Artist Control wheel sensitivity adjustment in EuControl, but that just makes you have to move the wheel more clicks (that detented wheel sucks!) before it actually registers the same jog distance.
It sounds like you have a good workaround!
Like I said earlier… the Artist Transport Is completely smooth, so it isn’t a Cubase problem.
It could be that the Control sends a different EuCon jog command than the Transport does, but I don’t know that for sure, or even if that can be changed if necessary.
You should surely post this question over at the AVID forum, someone there is sure to help!
