Sounds more like an alto...
its definetly real though. you couldn't get some of those neat human inflections without an impractical amount of work if its physically possible to do it at all.
nice tone to the person who played it though (i'm an alto player myself), wish i could get my sax to sound like that.
the 7 was because despite it being very chill, it velt sort of empty to me, and the solo very simple. i liked it, but i feel it had more potential
