Enhanced Mix File Commands
Whilst the basic set of mixfile commands is sufficient to configure the
Imagestore 750, there are some extensions to these commands that provide
advanced functionality.
Input Bunch Profiles
AddToMix
AddToMix sources assigned in the mixfile and are usually fixed, however,
there may be a need to change between sources during operation. Typically,
this re-routing is known as ‘input shuffles’.
Input Bunch Profiles provide a way of implementing ‘input shuffles’ by
allowing the user to externally modify the content of the mix during
operation by switching in and out various sources. Input profiles act as
enables and are typically used where a selection of input sources have to be
supported.
Each input bunch has a profile associated with it. Input Bunch Profiles can be
controlled using existing input shuffle Automation commands.
Each GainType associated with an AddToMix command can be given an
InputProfile value between 0 and 31. The relevant GainType (switch) is
only then enabled (included in the mix) when the InputProfile parameter
specified matches the Input Bunch Profile value set externally by Automation
control. If the Input Bunch Profile value is different from the mixfile, the
specified crosspoint will be excluded from the mix.
If the InputProfile field is omitted from the AddToMix command, then a
value of 0 is assigned and the specified GainType will only be enabled when
the associated Input Bunch Profiles is set to (or left at its default value of) 0.
Inputs can be included in a variety of mixes as defined in the mix file but the
user may only wish to include them if certain conditions are met. The
