Thanks Jim. The I learned two things.

1/ I use speaker line out of the computer to my speakers. I am pretty sure that is analog. But I did not know that some send their computer output to a USB box which converts to analog and sends to a speaker.
2/ I did not know about the buffer size concepts. That makes sense. I am guessing the video for recording midi with BIAB should talk about that.

I also put it in my Course outline: Getting the BIAB midi (melody and solo tracks) to sound real
