Adar, I finally got it to work. I reinstalled 2019 BIAB, at the end of the install it asks what kind of DAW you have and it lists various ones like Cakewalk, Reaper, Pro-Tools, but not Mixcraft. Originally, I did not check anything because I didn't have any of those listed. This time I said what the heck and I checked all of them. As a result it put all the plug-in files in the Plug-in aax folder instead of outside the folder like it had the 1st time I installed. Now, Mixcraft can find it, works perfect. Oh, the little confusing details!!
