For me it was very refreshing to read your post because since I bought BIAB three months ago I have really been struggling with it and Like yourself, I am not a stupid person. I have the Megapak and recently bought the Ultrapak as it was on a special offer, however I have now returned it as I could easily spend more time working with BIAB rather than playing my chromatic harmonica and all I wish to do is create some backing tracks to accompany myself.
I wonder if it would be very difficult for PG Music to offer two versions of BIAB - the present, very complex one and a much simpler version for the many people who simply wish to have an accompaniment for their instrument.
