Were you able to purchase the Cat6 version? I tried to do it myself some years ago, but I never got the software. However. After updating my stationary computer with the latest software of Windows 10, I have been able to run the Musicator Delta on it in a so-called "Compatibility mode" for "Windows XP, service pack 3". This works 100%.
