Hi Lucas,
I have actually figured all this out (presonus studio one support was no help). The process is a bit involved but workable. I will post links to get you started but in general:
- First I had to add the xv-5080 as an instrument, it will receive midi from the motu 828 midi express Port 1 (motu output port)
- Add a second keyboard (Komplete Kontrol S88) input Komplete Kontrol - 1, Output Motu Midi Express Output Port 1
- to switch sounds in the 5080 it has to be in performance mode (multitimbral) and you use the track inspector on each Instrument Track (xv-5080 is the instrument created above) and the bank/patch setting. the 5080 uses MSB/LSB patch number and bank to switch sounds, in studio one you have to combine them. The patch number below is the calculated MSB/LSB, bank is 1-128 (if the bank has 256 the patch number may increment from lets say 11414, 1-128, 11415 1-128 this is the SR-SV80-14 Extension board):

See these links for more info, I am up an running, it is not very user friendly but it is working and I have multiple tracks all playing input from the 5080 via S/PDIF. Copy the following link into browser:

There are three additional links at the bottom of the page above that give additional info. I had to also go to the Roland site and pull down xv-5080 documentation on External Card patch lists etc. because my Sonar setup just had the instrument definition that I setup 8 years ago so I forget EVERYTHING about the in and outs of working with the 5080.
