## Orchestra Detector
-An Orchestra detector is a special type of **readOnly** positioner that uses Orchestra to sample the most recent value of a monitored EPICS channel with no waiting. This can be used, for example, to monitor the synchrotrons storage ring current that is provided via an EPICS channel on a pixel-by-pixel basis with minimal overhead.
+An Orchestra detector is a special type of **readOnly** positioner that uses Orchestra to sample the most recent value of an "Epics" or "Tango" data channel with no waiting. An Orchestra detector being configured as a type of positioner is an historical artefact that may be corrected in future. This can be used, for example, to monitor the synchrotrons storage ring current that is provided via an EPICS channel on a pixel-by-pixel basis with minimal overhead.
