Tonight I tried out Studio One Prime for the first time and started out with a new composition. I had hoped for a wow moment, but... the wow factor never really set in.
So I returned to MuLab, and everything just fell into place.
Sometimes it doesn't matter what advanced features are available, I guess. It's more a matter of workflow and what style of music you're after (I have never really gone past the eighties).
What can I say: Go MuLab!
