+#X text 67 343 To use this patch \, connect your audio output back
+to the audio input (any input and output channel from 1 to 8 \, but
+the input channel should agree wih the "inchannel" control at top).
+Then adjust gain so that "RMS amplitude in" is about 65 (anywhere from
+60 to 70 will do.) The latency is measured once per second. If there
+are interruptions in the audio the button above should flash (whether
+or not the audio system reports the error).;
