OK guys, some success but inconsistancies, perfect operation sometimes and then corruptions take place.
Even the Tyros midi function page gets changed and BIAB takes a resetting like going back to Prefs switching off those new instructions to get any normal BIAB function like having to go back to the green arrow again.

AND when working how do you get the automatic start to stop at the end of the play without using the stop button at BIAB.

Perhaps I need to come back in a few days when the old grey matter as solved these problems for me.

Will be in touch and thanks all for your guidance.
