hate to tell you i have had no issues with win 10 and U-Mix ,,
you kinda need to start at a set point ,,
first issue to eliminate is the U-Mix driver for sc is 32 bit ,,so start with useing the 32 bit version of software ,,
now for info
what os ver where you running before new computer
any know issues with runing Cross and what version
maybe not understanding but did you install the U-Mix Control panel
do you have the check box checked in audio set up to start with mixvibes products
are you useing correct MIDI mapping ,, you have to select the one you want when you do a fresh install ..
screen shots of gui and preferences tabs audio and MIDI ,,might help
start running Cross in 32 bit mode and verffy thease thing are correct and tell us the outcome ,,
