ISIS® Software for PHOENIX XT and MENTOR

HTP-FTP-LTP Modes20.13 SummaryISIS 〉offers a number of modes that can be used to control channels: these are HTP, FTP and LTP.HTP is the normal operating mode for intensities: channels that are in use in more than one field areoutput at their highest used level.FTP introduces a system of priority through the working fields. This means that a parameter used inmore than one field will be output from the first field in the priority list.LTP offers complete flexibility for the advanced moving light programmer. The desk output is takenfrom the last used field.Each control channel has a definition associated with it, so that the system knows what sort of channelit is and how it should behave. A generic channel uses the ‘standard’ definition, which contains only anintensity parameter.Channels that are defined as colour changers or moving lights use a definition, or personality, that isspecific to the instrument being controlled.The HTP, FTP or LTP mode is selected in each instrument’s definition. Normally, all parameters withinthe instrument are in the same mode, except intensity which is HTP. However, ISIS 〉 allows eachparameter of an instrument to be configured independently into HTP, FTP or LTP mode.To use LTP mode, the submaster and playback fields must be configured. This also allows theoperator to select specific areas of the desk that will ignore LTP action.Parameters within each submaster can be configured to work in Jump mode, where the contents areimmediately sent to the output when the fader level exceeds 5%; or Fader Control mode, where theparameter values increase in relation to the fader level.The HTP, FTP and LTP concepts and their use on the desk provides the operator with completeflexibility and control when programming and using moving lights and colour changers.Page:458Issue 1.01www.adblighting.com
