Recording with a tascam US 16x08 interface with Reaper. No trouble for several years. After not using it for some time when I recorded some vocals they playback scratchy, out of time and way out of tune. Tried the obvious stuff, recorded on several different tracks different songs new project no help. turned off all FX. Monitoring sounds good. Tried different inputs on interface, no go. I fear ts a Windows update conflict. Anyone have any ideas. To wipe and reinstall would be a huge deal. Waves licensing etc.
