Problems with pad sentivity and OS1

when i changed the pad to upgrade them. the velocity with OS1 is very weak. i have to hit them pretty hard to have something (merely 90) even with the sensitivity adjustment all the way up. i used the "A" velocity for this.

i tried with the akai OS 2.12 and it works fine.

does anybody got any clue about this?

yo i have mpc2500_xl114.osx
and experience this the other day only on pads 13 -16 what ended up doing checking the velocity screen look for the jjos manual it shows u yeah it seems to have cleared up after i did this peace good luck!

thanks, i've heard that it could be easier to set the pad sensitivity with a threshold or something with os2.
does anybody tryed this?
