Thanks for the reply. I realize now I probably didn't clarify my post very well, my apologies.
My situation is this; I write a lot of songs, both instrumental and with lyrics. Because of my lack of proficiency in writing musical notation it is a struggle to get it onto paper in the proper format. I believe there are some musical notation software programs that will take an audio file and transpose it to a musical score for you. I believe Forte 7 will do this, though I could be wrong. I don't know if BIAB has this function,
however I was told that if you played a piece on a keyboard that was midi compatible and connected to BIAB then it would indeed transpose it to a written musical score as midi recognizes the piano keystrokes as a note and attaches the proper note value to it. I am not sure what equipment is required to accomplish the same thing with a guitar. I am certainly intrigued with the Godin Multiac though as it's the only guitar I know that comes wired with midi outlet.
If this worked it would mean I could play one of my tunes and have BIAB transpose it to a musical score.
I hope it's possible, even if I need some additional equipment
to make it work.
