Hi Steinberg,
I just wanted to say thank you for the Hal 5.1 update, and a special thank you to who ever was responsible for the pan control to arrive in the mapping window!! 
I’ve personally wanted this feature for a while now & i’m so glad it’s been seen to. It’s not a major thing but now if you have various samples on the same keyboard layout you can do most things you need to without leaving that window, nice!
Kind regards, Codsworth
