"If actions are placed within a repeated section of music, the wait field allows you to specify a number of times to wait before performing the action. For example, if you repeat measures 10-20 three times, you can tell Sinfonia to mute the flute the second time around by specifying a wait value of 1 (Sinfonia waits one time before performing the action). If the wait value is 0 or left blank, Sinfonia will assume you want the action to be performed every time. Be aware: if you specify a wait value other than 0 and your action is not placed within music that is repeated, the action will not be performed (Sinfonia will be waiting for that second or third time around, which won't happen if there are no repeats)."
