My last 32bit hold out for a while has been NI B4-II. I’ve used it in dozens of projects over the years, and I still use it live with 32Lives and MainStage. Though I’m weening my way off with Acoustic Samples B5, I’m not ready to ditch it quite yet. Due to High Sierra’s updated video processing, I may be forced to update at least SOME of my computers in the near future.
Is B4-II compatible with High Sierra?
