If you played on 5 (not 6) it is amount of seconds in delay.
The score is shwing that you are ready to memorise your Right hand. For that you can press R and H
Please, show me, how you play with your left hand
I can not work on the left hand until I get a new piano I am working on selling my full size keyboard since it won’t work with the program and get one that will and hopefully by the end of the month I should have it but I can work on memorizing the right hand a while
