figured out a little work around in ableton
go into midi preferences and click the little arrow to the left of the port you want to use
in the drop down menu, click the port type button once so it changes
ctrlr should now be able to use this port. it’s great if you want to use the external instrument, i usually group one of those with the ctrlr plugin so it’s all on one track
not sure if this was obvious or w/e but it’s been handy for me
cheers
