I am SO impressed! This is all quite new to me and far beyond my capabilities. From I can figure out, what is X? T=title? M=meter? Q=? K=key? Letters=notes. numbers=beat value? Small c (if key=C)= "do?" I agree, last E should =6 if not 12. It's all repeated with the final note on "do." What are all those red numbers in columns? Is there a guide for computer dummies in plain SIMPLE English??? Ever hopeful, Sheila
