i installed a time machined os onto my computer and it all works great, except there is a midi device in audio midi setup that "says" its still running and in use, but nothing is connected and it has not been for a while. at one point, this was connected to a yamaha m7. no longer! yet it will not let me delete! please help!

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Audio. See if the driver is there.
Also check the hard drive level Library/Audio.
Edit a MIDI configuration
on your Mac, choose Window > Show MIDI Studio.Open Terminal in Utilities. Have not attempted this command in Big Sur but try " kextstat " without quotation marks. This will list out all loaded Kernel loaded. See if there is a listing for you Midi. Then at least e might get some idea if it is loaded.
User wrote " i installed a time machined os onto my computer " - are you meaning Time Machine Backup was use to Restore the OS on the computer ? It the issue at hand exist before TM was used to restore the OS ? It would help to understand the sequence of events.
On an older version of macOS Catalina https://apple.stackexchange.com/questions/375483/how-to-remove-a-sound-output-device-created-by-an-application
as stated previously, I have tried this and I am unable to delete the old configuration -- that app will not let me. I appreciate the instruction but it is of no use here. Is there anything else I can try?
I transfered my os from old computer to new using time machine. So this issue exists on the old computer as well. This is the only glitch I cannot resolve. It affects nothing in the operation of my computer -- I just want to understand why it does not delete the old device
Thanks for this -- I have no experience running scripts, but I did look all over for any Yamaha SM7 stuff I nothing that I can find is left. I would then not know how to scrub for it via scripts and the searches are coming up empty. so really this is not at all helpful I am sorry. Is there any suggestions? I would really love to clear this up. It seems that whatever is in there is grabbing ahol of a port at startup and not letting go. The device is not greyed out and cannot be deleted...
Thank you. Will look around and see if we can find a solution and get back to you.
I can find nothing that says to me YAMAHA M7 or SM7
Is there any way to reboot the Audio MIDI preferences/cache?
This is great. How do I know what I am looking for?
I see nothing for MIDI really that would pertain to the Yamaha or anything...
At this point - am reaching the end of possible solutions to offer.
Maybe, if you repost, condensed version, a more Knowledgable Contributor will pickup and assist.
No worries -- I am grateful for all your help. I am gonna reach out to some Audio people and at Yamaha to see if they know...
