Thanks for replying to my original post. Im new to all this, and its nice to see people willing to help out. I followed your steps to insert a bass line.I dragged Presence XT to the track listing, creating a new track and bringing up the overlay. I found my bass plug in (it was already listed because I had loaded it before). I turned on the record, solo, and monitor buttons on the left hand side. I clicked record, my other track played in my headphones, and the green highlight came up for the bass rack, meaning it was recording. I played along using the keyboard, very crude I know. Finished, and it didnt record. Played it back, no sound from the bass track from Presence. Im using Studio One Prime, I havent upgraded yet, so I do not know if this issue is just a feature I havent paid for yet?
