Hi all - I’m a dusty old time user of N-Track, from the very earliest days of digital recording. N-Track is such an awesome piece of Software, @FlavioA ! Congratulations on the results of decades of hard work!
In my situation, the company that made when my 8 ch A/D converters, which at the time were the most expensive part, went belly up, there were no more driver updates. So some time around 1999, I decided to remove the internet connection and freeze this Windows 95 relic in time! It has worked with the reliability of a toaster ever since!
Well, fast forward 22 years later and my old Tascam mixer died. 
I’ve been looking at the mixers today and I am strongly considering a digital unit, like the Mackie Onyx or the Tascam units, which give all the analog controls but will send 24 tracks to a shiny new version of my beloved N-Track.
Given that back in the day I had to build a hot rodded, overclocked, somethin or other, what is required on a DAW today? I want to build it with the computational power to handle like 24 inputs in 24bit/96Hz, so that it will last into the next millenia! Does anyone have any insights into what is important in a new DAW?
Thx!
