Sadly, the above post is not a solution as on my system none of the external midi commands for my guitar effects unit and vocal effects unit will change. Interestingly, in the step edit screen , I can click on each effect using the play button and the effect changes correctly on both units. I can only assume that it must be a bug in BIAB 2017 that stops then changing automatically.
