Help here is greatly appreciated. I have some B format recordings from the Soundfield that I've rendered down to stereo using a VST plugin in Nuendo but I still show 4 channels in the waveform / project. I have what should be left and right, and then two channels of nothing, which is correct. Does anyone know how I can take those 4 channles and export them down so I only a left + right stereo .wav?
