Do you show data from CMS/P3, DRL/P4, DRL2/M1, CMS2/M2 in EmotivPRO software?

Please note that M1, M2, P3, P4 are reference sensors. We don't show data from the references. Our electronics uses CMS (left side, P3 or mastoid) as the electrical reference point and DRL (right side) as the noise cancellation electrode. All signals reflect the potential difference between the EEG sensor and the CMS sensor. You can get relative signals between channels by subtraction - the common CMS voltage cancels out. For example, (F3 - CMS) - (F4 - CMS) = F3 - CMS - F4 + CMS = F3 - F4
