The first is a Kindle Fire HD8 (with Google Play support added to it) and when I select Google library, it exits the Midi configuration screen like it threw an exception.

Hmm, for some reason when I tried it today I didn't have any problems with Google library on the Kindle Fire. I could see SoundBrenner Metronome in the list and was able to select it. I could not figure out how to do anything with that so I installed the Mobileer Midi Scope as a test. Using the Test Midi command functionality I could see the commands show up.

So I am at least making progress toward the goal.
