thanks idatrod for your reply,obviosly this is a bigger problem than i first thought in regards to playing a G, Fsharp and Gsharp ,one or both of these notes playing accidently,it was only this subject that came up, was what made me mention it,i doubt if this will ever be resolved,because if this has been the standard for many years,then it,s not going to change,i have a lot of respect for all of you who have been in the business for years,i am starting to be aware of the problems that a lot of you had many years ago ,that i am finding out about now,it,s funny that when new members who come onto the site ask the same sort of questions i asked over a year ago,i can relate to them,anyway keep up the good work,mike
