Thanks for the comments Kara & I understand what you are saying about the bassline,but for me personally,it's more important to me that everything is tight & in sync.You being a bass player,I can appreciate your acute desire for realism,but then again,this is sort of a ambient/funk piece & an arpeggiated piano sound is not very realistic either.
I was not necessarily going for that much realism.
Of course,to each his own & I like the fact that your ears can decipher details like that.
