MPE not working correctly. line select mode 1+1

So, when you the use CZ V in MPE mode there is a bug when you use the line select mode '1+1"

in this line select mode 1+1 the MPE pitch does not effect the second line.

this means the first line goes up in pitch, but the second line doesn’t and gives a weird effect.

it’s easy to hear this bug if you detune the second line by ‘fine tune 33’ or more.
