Hi daveh,
Sorry to hear you have been having issues mapping the jog wheels on your VMS5. Unfortunately I am not familiar with that controller and I couldn't find the MIDI info for it in the user manual.
It does mention:
Please visit one of the following websites to view and download the VMS5.0 MIDI table chart.
www.americanaudio.com
www.americanaudio.eubut I was unsuccessful in finding it. If it came with a printed out MIDI table chart, please let us know the info for the jog wheels.
So far the only useful info I have been able to find is that it has
Dual 2000 point resolution touch sensitive turntable scratch controllers Maybe with some more info and back and forth we can figure out the correct settings in Cross DJ for your controller.
Best Regards,
