Welcome Anthony,

You have received good answers to your questions so I will add to question #3. BiaB's included sounds are General MIDI (GM)and as you know they are at the bottom of good sounds' category. So here is my workflow using BiaB.

Construct a chord progression and sometimes a melody using the included GM then transfer them to my DAW. BiaB has a number of ways to transfer your song so that is not a problem. In my DAW I will use my much better sounds.

Note I find it much easier to work in my DAW than in BiaB but others do a lot and sometimes all of their work in BiaB. It is a personal choice. I add this as I assume, based on your initial post, you are using a DAW and good sounds so it might be easier for you to do a lot of your work there.

I should note that I work almost exclusively in MIDI.

I hope this helps.

I just posted a selfie and all of the responses were get well soon!
