4.3.2 Configuration using Configuration Segments
A configuration segment is, like normal data segments, connected to sample data from
the waveform memory but no segment loop count is available. Each configuration
segment has a link to an entry of the action table and can initiate the execution of the
corresponding action while playing the associated sample data. One action consists of
one basic command or a so-called composite command. A composite command
contains multiple combined basic commands and allows building complex operations.
A configuration change based on action table entries becomes active with the next
sample marker. The minimum length of a configuration segment is 240 IQ sample pairs.
Sample markers are not allowed within these first 240 IQ sample pairs.
Each command has an individual length. This length represents the amount of space
required to store such a command in the action table, which has an overall size of 32k.
