If you pulled data from a controller using a USB drive, you can load the data files into Simple Client for streaming. This GIF shows how to add the USB data to Simple Client.
You will not see the MRK file when you go to load your controller file, but the MRK file must be in the same file location as the CSV, or the operation will fail.
After uploading the controller file, you will be able to adjust and stream the session as usual. Learn more about session management in Simple Client:
