Returns an array of event IDs of all events being members of the requested event group.
These are events which had previously been added to that event group
by calling the
by_marks() function acts as placeholder for all event
IDs of the particular group and allows to manipulate a set of events
this way with only one call.
After notes died, this function may still return those recently died
notes' IDs for a certain while, that means for example that
num_elements(by_marks($MARK_1)) may return a higher
value than the actual amount of currently active notes. This does not
mean that you have to remove dead notes from their groups by calling
delete_event_mark(). The sampler automatically
removes dead notes from their groups automatically after a certain
amount of time, and in practice this lag does not have any negative impact
on using this function, since all built-in functions automatically
detect invalid IDs and are automatically ignoring IDs of dead notes.
|Event Group ID Number
|Event group that shall be referenced. You should pass one
of the built-in constant variables
$MARK_28 for this argument to select one of the
28 available groups.
|Event ID Array
|Event IDs of requested group.
The following example implements two "exclusive" keyboard zones with a
split point at key
36. The script enforces that only
notes of either one of the two keyboard zones may play at the same time.
So for example if you start playing notes left of the split point, all
sounds play as usual. Now however, as soon as you hit a note on the
right side of the split point, it will cause all notes left of the split
point to be released immediately.
- on note
- if ($EVENT_NOTE < 36)
- set_event_mark($EVENT_ID, $MARK_1)
- set_event_mark($EVENT_ID, $MARK_2)
- end if
- end on
