Reaper can't open Boss DR 880 midi inputs
I have the Boss DR 880 drum machine set up in Reaper with the input and output enabled. When I close the midi devices set up window in preferences, an error message appears: "The following midi inputs/outputs could not be opened - Boss DR 880."
I have set the Boss DR 880 USB for midi and connected the USB to the computer's USB port. It shows up as an input/output for me to select in midi devices in preferences and I have them enabled. How do I get Reaper to open them so that I can use the external drum machine?
Thanks,
