Yamaha CK61 Transpose?

Hello, I recently started using a CK61 as my main keyboard/controller. I trying to use the transpose feature on the CK to transpose songs. The CK sends sysex for the Transpose. It is the same message whether I am incrementing or decrementing pitch. The sysex message just increments the value byte starting at 40h (64). I’ve decoded the message to a CC and created a binding but I’ve not figured out to use a single CC to transpose up or down based on the value. I hope this makes sense. Any suggestions would be greatly appreciated. I’ll continue to research as well. Thanks

Think I figured it out. Decoded my sysex message to CC 80 and grabbed the value from the message. On a binding for CC 80 I set my Target to Song/Transpose and then a Mapping Expression - Input - 64. Working so far. Thanks
