Is there an element or arrangement of elements that would allow me to capture and save just the first output sample for use later in a session, For example the nested element may send out a dominant frequency calculation every 5 seconds. Can I capture that first output and save it for use later? Thanks George

In1 : Out1 The Out1 variable is set to 0 on start, so if you want to remember a value which is different then 0, then the above might be the easiest. Another way would be to use some events, e.g. PROCESSING_STARTED in SystemEventSource and set a value shortly after that. Jarek
