After much experimenting I was able to get my Tango 1 and the extension bay
functional on Mac OS 10.13.4 (High Sierra) in combination with Logic 10.4.1.
Interestingly almost everything that didn’t work now seems to work including
the sends. I am using Net Smart 3.3.0. Iggy / Sassi software build 3.3.0.16,
console software 3.2.5.1 and firmware2.4.1.10. I will do more testing this
week. The big advantage is I can now use a more modern computer running the
most recent OS and the current version of Logic X, with a Tango unit that so
far is fully functional. Next step is to pull out my active extension bay and
see if I can get back to my full 32 fader setup. It’s a good day in Hollis NH 😊
