Thanks for the replies!

I just found this:
https://www.irealb.com/forums/showth...gacy-software)

So it DOES exist, but is unsupported.

I would be willing to try it, at my own risk, if I could find it anywhere. Now I am curious!

The Android on the pi is a Great suggestion! I will do it and post in the Android forum if it works well.

I have looked at cheap tablets, but I live on Social Security and the reality is, alas, I cannot even afford that at the moment.

And yes, as a vocalist I am finding this software incredibly helpful!

Thanks!
