may also support user-definable minimum and maximum limits in addition to the system minimum and
maximum limits. When performing increment and decrement actions on integer parameter commands, the
parameter saturates at the minimum or maximum value (as opposed to wrapping).
Float
Float parameter commands control floating point valued parameters with minimum and maximum limits
specific to each command. The argument to a float parameter command is a floating-point argument. Float
parameter commands may also support user-definable minimum and maximum limits in addition to the
system minimum and maximum limits.
Float parameter commands support the get, set, inc and dec actions according to the command's read-write
mode. When performing increment and decrement actions on float parameters, the parameter saturates at
the minimum or maximum value rather than wrapping.
Sequence
Sequence parameter commands control integer-valued parameters with values in the range of 0 to
4,294,967,265 (2^32-1), inclusive. The specific command will most likely impose minimum and maximum
limits more restrictive than this range. The argument to a sequence parameter command is an integer
argument. Sequence commands do not support user-definable minimum and maximum values. Sequence
parameter commands support the get, set, inc, and dec actions according to the command's read-write
mode. Sequence parameter commands do not support the tog action. When performing increment and
decrement actions on sequence parameter commands, the parameter wraps rather than saturating. In other
words, incrementing one past the maximum will set the parameter to the minimum, and decrementing one
past the minimum will set the parameter to the maximum.
String
String parameter commands control string parameters. String parameters are user-defined text arguments
and conform to the requirements as defined previously. String parameter commands support the get and
set actions according to the command's read-write mode. String parameter commands do not support the
inc, dec, or tog actions.
List
List parameter commands control parameters that correspond to a list of pre-defined strings. The strings
are defined in a pre-determined order by the SoundStructure firmware. The string arguments of list
parameter commands are system-defined text arguments and are formatted as described previously. List
parameter commands support the get, set, inc, and dec actions according to the command's read-write
mode. The inc and dec actions change the parameter's value to the next or previous string, respectively.
When incrementing or decrementing beyond the end or beginning of the list, the parameter wraps. List
parameter commands do not support the tog action.
Acknowledgements
All parameter commands result in acknowledgements from the SoundStructure device. Acknowledgements
are generated with the same syntax as the original command except that they will always indicate the val
action (for "value").
Acknowledgments are generated when either a parameter command is issued or a parameter changes
value for some other reason. When a parameter command is executed with the get action, the
acknowledgment is only sent to the control interface that the parameter command was received from.
