Need Help installing Tutka midi tracker

[johnnyboy5000]

Thanks, but I'm still getting the Error: Dependency is not satisfiable: libqt5core5a (>=5.12.2).  So if there were a way to update libqt5core5a  to >=5.12.2.  I think my system is 5.9.  I'm on the most current Linux Lite 4.6. 

Do you know a good tutorial  to install tar files?  I'd like to learn this technique.

Thanks again for your help.
