Studio Mode Has No Data Loss Configuration Option for Desire Fixtures
Unlike the other modes, Studio mode is the only mode that allows for local control of the fixture. Since it has a local control option, it will revert to local control upon loss of DMX. The fixture will retain the last level sent via DMX as its local level when DMX is removed, which can mimic hold last look forever behavior. You can use the lightbulb button to toggle between the set level and off; should the fixture stop outputting when DMX is removed, press the lightbulb button to restore the local level.
