John.... Can you shorten the legs on the music rack that fits into the 7K? Or maybe do some bending of that rack?
In order to avoid hitting the 7K screen-board when I turn pages I put a piece of wood on the rack to raise the music book which also makes it nearly impossible to see my audience, except for those who are awake and to my right or left in their wheelchairs!
When I played at the Sr. Center, on stage, I had the same challenge you are having.... I lowered the stand the 7K sits on... that works too....I understand the "too old to stand up" part....
Hpppy playing! Elizabeth
