Hi Hypersolid,
Incase you couldn't figure out how to try running Cross DJ in 32 bit mode, you have to go to your Applications folder in Finder on your Mac. And from there you can right click it and go to "Get Info" The page that comes up should have a check box with "run in 32-bit mode"
Check that and then hit okay at the bottom of the page.
However, I do not know if that will help or not. I think I have also been corresponding with you on Facebook, but wanted to respond here incase any other users run into the same issue.
Please check to see if the U-Mix is showing up as an Audio and MIDI device as shown here:
https://support.Apple.com/en-us/HT201840Also this message is displayed from the U-Mix Control panel on more recent OSX/MacOS versions:
Unable to control input level. Please use the Mac OSX controls in [Audio MIDI Setup] select U-Mix Control Pro in [Properties For] and see the [Audio Input] section.The U-Mix Control (all versions) should be a core compliant sound device on more recent versions of OSX/MacOS so the control panel and drivers are not nessecary. You may want to check and make sure you have the most recent firmware found here:
http://forum.mixvibes.com/downloads.php?cat=71That is for the U-Mix Control Pro 1 only, but might help if that is your version and the device does not show up in the AudioMIDI Setup App on your Mac.
Since the device is core compliant it should work in the 64-bit version of Cross DJ.
I hope this will help!
Regards,
