I was excited to see reason showcased in one of my favourite new youtube channels called Mac Address, an offshoot channel of Linus Tech Tips. Sadly, Reason chokes hilariously on the new mac M1. Not a good look for the Macbook pro or Reason. I don't personally have these issues since I use a mega PC computer but just thought it was fitting that the great macbook pro and reason 12 could not do the job they are expected to do for this musician. Now of course, he could just have a poor working method. It's up for discussion or debate.
My perspective is that I love reason because it is the one that clicked with me young. Other than that, I think it needs a lot of work still in many ways. Other programs are so much more efficient in every imaginable way. What keeps me sticking to reason is the fun factor and familiarity of it. That won't change for me, pending RS doesn't screw up on R13 or impose stupid subscription models as the only option.
Also for all we know, his issues lay with his audio interface etc.
