2 Questions

1). There is going to be a "Alida-2"? WOW!
2). What is the status of "Musica" or what ever its called now.

La Musica was renamed to Lisssn

It was recently released for Mac OS 10.11

I don't know about Alida 2.

The work on Alida 2 has come to a halt at least for now per the developer.

Lisssn for PC is coming soon. It is being beta tested now.
