+## 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.
