EEG data save with Designer

Hi, I am new user. I can run OpenBCI, can connect and play Openvibe and can view signals by OpenVibe designer. But confused how to save the signals in CSV or any workable format. I can save in mxs format only. But I can't work with that while offline. How to store/save in CSV format ? Please guide me.

Re: device drift is too high

I think, you can select OpenBCI then connect and play. With SELECTING LSL, I faced a lot trouble. Select PORT COM1 and it will fix the problem.
