OK I figured the puzzle out. It's a problem with the location of soloists that use SampleTank or Amplitube. For some reason I can't find SampleTank or Amplitube on my computer. But SampleTank does come up but says it's expired. So I would like to implement these tracks back to Cakewalk TTS. Unless I learn where the directories for these programs are. ARe there special editions that are being used. I own both Revalver and Guitar Rigg. But it would be nice to hear the amplitubes plus they are already set up. Also in a couple months I plan on buying Biab2020 Has the setup changed from 2015 much? Should I wait or is it an extension of using these VST's?
