In speaking with Waves Sales and Support today 11-15-21 due to their humongous sale, the DTS Neural Surround Collection, Abbey Road Studio 3, NX Mix Room and all of the other Surround Sound products are not compatible with Studio One version 5. When I asked for a list of host applications I was informed: Reaper, ProTools, Cubase, LogicPro and several others but not Studio One. It seems all of my work is held hostage at 2.0 sound at least currently or do a stem export into Reaper or I'll have to Upmix from 2.0 to 5.1 by using Reaper with the above plugins. All clunky alternatives.
