The control source will update machine parameters over time, based on the events from the sequences and the patterns. One control-source will handle one single parameter. It implements the logic of computing the parameter value for a given time, taking multiple tracks and overlapping patterns into account.
At the begin of the timeline (ts==0) all parameters that have no value in the sequence will be initialized from “default-value”. For trigger parameter this usualy is the no-value. For other parameters it is the last value one has set in the ui or via interaction controller.
BtPatternControlSource * bt_pattern_control_source_new (GstObject *object,const gchar *property_name,BtSequence *sequence,const BtSongInfo *song_info,const BtMachine *machine,BtParameterGroup *param_group);
Create a pattern control source for the given machine
and param_group
. Use
gst_control_source_bind() to attach it to one specific parameter of the
param_group
.
