Sorted it, well not sorted it but found a way round the problem.
In the MFC turned xp2 off turned xp3 on and assigned it to control function 16 as xp2 was set and all works fine.
I am convinced the problem is xp2 something has been screwed up in the update to 1 which has turned my xp2 into a bizarre random editing then mute / bypass pedal.
I,m just hopping this has sorted it and there won,t be any more surprises, I only need 2 expression pedals. Maybe this might be sorted in the next firmware update, I tried to update the firmware in the MFC another 2 times it seem to update ok and factory restored the MFC twice but it didn,t fix, I altered every setting in the ultra i could think of but with no joy, at least I have learnt a bit about midi settings and communication.
Hope this helps someone else out.
