WOW!!
2022 and this just saved me from an ongoing headache
The combination of using the fine stylus from my Wacom to calibrate the screen and using my "finger nail" instead of my big fingers when making selections has made the Artist Control quite responsive.
Calibration with my fingers never gave acceptable results.
I had gotten in the habit of using the iPad to compensate but for many functions it becomes somewhat unintuitive to work that way.
One of the biggest reasons I use the Artist Control is for the 8 encoder knobs for the inserts/plugins.
At any rate this has made a major difference. thanks.
