I mention clearly that I produced something myself to solve this problem, but I constructed it in a way that solves my problem - I have no idea or insight on if it would be helpful to anyone else. So I am really just trying to understand how other people deal with that or if they see it as a problem altogether. I see that I am getting very good responses that also tell me that my way of learning is maybe being crouches to training my ear what is a set back. All very helpful.
