 05-18-2018 1.2.1
 	-Added looping enabled parameter
-	-Added button to rewind to beginning of selected time range
+	-Added button and parameter to rewind to beginning of selected time range
 	-Flush old stretched audio faster when source audio is changed
+	-Fix time range not being recalled properly when loading host project
