Hi all. I have a problem with old equipment I wish I could get rid of. Anyways, I have 2 S4 Revolutions programmed on an ETC express. Everything is working except for the gobo rotators, which appear to be patched correctly. Any ideas why this would be the only function not working? They worked previously, but fidgety fingers got into the board and we had to restore the settings to a previous show. Thanks.
