Found what is happening but still can't fix it. The Pioneer needs Hex input. I can get the MSC-400 to send Hex when triggered by PC through USB connection. However, when I drag the triggers to the MX-980 and use it, the MSC-400 sends ASCII.  I deleted and rebuilt the device making sure I used Hex when building the Func table. Something is setting the output to ASCII when I use the MX-980 triggers but what?   Help please.
