CoreConfig how has a playback mode option which can be set to reprocess or read. Setting it to reprocess means that all derived signals are reprocessed during playback, in this case the PlaybackEngine only plays back the signals whose source is set to "origin" Setting it to read means that all derived signals are playedback from the recorded buffer, this whill be the preferred mode once offline processing is set up which will allow for more complex data processing offline once a recording is completed, which would require the read playback mode as it wouldn't support realtime processing as reprocess does
