Hi Noel,

Thank you, that is indeed helpful. Especially about asking dumb questions as I can feel hesitant to ask something that I think is probably obvious to everyone else. I know that without the help that I've received from people like yourself on the forum I'd be floundering in BIAB by now.
I've got BIAB 2018 megapak. I'm learning to play traditional music on the chromatic harmonica and while there is obviously quite a lot of styles included in the Megapak I am considering upgrading to the Ultrapak, but, considering the cost and the fact that I'm only using the backing tracks for my own pleasure/entertainment I am a bit hesitant and shall continue to explore the contents of the Megapak for the moment.

best wishes

Narayano
