Great, that's good to know about latency.. Never to old to learn, huh?? I appreciate your help.. It's going to be a totally new world & learning experience for me.. don't know why I held off so long, other than I was so comfortable with the Korg.. Just save my tracks as separate wave files from BIAB, import them into the Korg onto separate tracks, & I'm good to go. But the Korg won't do Midi. I guess I could import the Midi files into Real Band, render them into separate wave files, (if that can be done), then to Korg. But if I can get comfortable with Real Band, it'll save a bunch of work & time.
I find there are lots of Midi files out there I can use for country & fiddle tracks.. & by importing them to separate tracks, I can work with them.
