HTP vs. LTP
HTP (Highest-Takes-Precedence) and LTP (Latest-Takes-Precedence) are terms used to define
the output of a channel parameter that is receiving data from multiple sources. In HTP, the highest
level of all sources will be executed. In LTP, the most recent level received will be executed.
Submasters are only capable of controlling HTP intensities. Cue lists can operate as HTP or LTP for
intensity parameters only. Non-intensity parameters (NPs) are always LTP. Eos’ default cue list
setting for intensity is LTP (see
).
HTP
HTP is only applicable to the intensity of a channel. HTP channels will output the level that is the
highest of all inputs. HTP channels are also referred to as “pile-on”, because as control inputs are
added (for example - you may bring up cues and multiple submasters that all have the same
channel recorded at various levels), the system calculates which input has the highest level for that
channel and outputs that level for the channel. As control inputs are removed (you pull some of the
submasters down to zero), the console will adjust the channel level, if required, to the highest
remaining level.
LTP
LTP is applicable to any parameter of any channel. LTP output is based on the most recent move
instruction issued to the channel parameter. Any new values sent to the channel will supersede any
previous values, regardless of the level supplied.
Eos determines the LTP value for a channel, which is overridden by any HTP input values that are
higher than the LTP instruction
