Studio One is already $200 here in the States for Thanksgiving. I wouldn't be surprised if they gave that as a cross grade price in the meanwhile for SONAR, which is lower than their regular cross grade price.
I imagine I'll carry on with SONAR for the meanwhile - I'm sure next year Studio One and every other DAW will be similarly priced and I'm trying to figure out Maschine Jam. I'm too old to figure out too much new software at a time. I hope nothing breaks before next year w/ SONAR - it shouldn't. I'm already running it on win 10 and win 7.
But Studio One does sound interesting. I'm not really a power user but use mostly softsynth>audio with a few tracks of vocals and guitars. I only do a little "band" recording that needs some of the esoteric editing features. For me, Melodyne ain't a tool, it is an effect. I'll fix a note or two but not a performance, that is the singer's job.
Maybe Studio One is a fit for me?
