Hi Wayne, sorry for the late reply.
Yes, switch to the Studio One, keep the Boss and Tascam gear! I started my recordings with a Tascam Portastudio 4 track. I have a boss Micro BR as a sketch pad too.
Boss make a piece of software that takes the proprietary format of their recording devices and converts them to a wav per channel. So, in theory, it is very easy to do your session on the Boss, convert the stems to wavs and then drop them into a song in Studio One for editing. You need to be able to plug the Boss gadget via usb as a storage device not an audio device.
Here's an article on the process from you device to windows.
I hope this helps,
