Hi REDFLAGS, wand welcome on this board.
yes ,you can change global velocity using MIDI CONTROL CENTER . if you don't have it , you can get it here :
https://www.arturia.com/support/updates&manualsfrom there, with your minilab mkii connected, go in the "device settings panel" located in the upper-right area of the software.
in this section you can set global velocity to : linear, logarithmic, Exponential, Full.
Hope this helps,
best,
