Well, this is incredible! It has been a long while since I posted here and (I'm not surprised) that this community is always willing to help and not bash because some breach of etiquette in the location of the post. I felt it important to address all of the excellent responses to my post in the same reply. I want to call out each of you though. Matt, I know you have been around here for a long time and I have learned much from your guidance to so many in this community. Same with Charlie Fogle (thanks for the attachment! I love Brent) and mrgeeze. Rusty and BD, nice to meet you.
That said, upgrading is a no-brainer for me now.
I am a worship band player. I have used Band in a Box to create chord progression snippets to practice improvised solos over (although I usually get replaced by our younger guitar hotshots!, oh well). I do also use BIAB to create tracks for my song ideas. And I love the BIAB plugin that I use with Studio One. Port the tracks over and then I can use my Presonus recording gear to complete the song.
For separation stems (legally) I use Moises. I purchase the songs from Itunes. I have made many backing tracks using Moises that my singing partner from church and I use when she and I do acoustic sets for hospice patients and nursing facility residents. I know that you can record songs with Audacity and bounce to MP3 but I am opposed to that.
Sorry to be lengthy but I wanted to do justice in responding the the thoughtful replies.
