1. If you plan to use MTS-ESP tuning mode: install the libMTS library by running `libMTSWin_v1.02.exe`.
   A newer version may be available here:
   https://github.com/ODDSound/MTS-ESP/tree/main/libMTS/Win
2. Place the `XenRoll.vst3` folder anywhere (preferably in your VST3 plugins folder), then point your DAW to that location.
