Gilbert,

Thanks for clarification I'll have to try that this evening.

This morning 'round 5 before heading to the office I tried the procedure I have been using on the Tyros4, S910 and CVP 307,( not the one just outlined by Gilbert) the behavior on all 3 instruments is pretty much the same, when you save a 2nd time the settings to RHY1, RHY2 and BASS do not save according to the latest changes I made. As John brought out in his post RHY1 seems to be all over the place. Bottom line though at least from what I've observed that it's just not limited to the Tyros4.
