Thanks Dave for the help.
I have made some progress by doing a complete uninstall of ProTools and virtual instruments, deleted its directory under C:\program files, and then using Regedit to clean up as many entries as I could find that were for ProTools.
After I reinstalled, I was able to get midi into protools and the mini-grand virtual instrument. Now I am having a problem of constant popping and some crackling sounds on the audio output side of things. I am guessing this may be either a buffer issue or ignorance on my part about routing in ProTools. I'm a total MIDI newbie. I used PT 11 for several years to record audio through the Berhringer XR18 and that worked fine.
Thanks again .............. Dave,
Dave
PS: Images can be found at hodler dot dpix4u dot com/xr18midi That will give you a directory that you can see the files by clicking on the file names. And yes, I am a new years here.
