Fri Jun 13 15:01:06 2014 UTC (9 years, 10 months ago) by schoenebeck
File size: 4396 byte(s) 
* Implemented built-in instrument script function "set_event_mark()".
* Implemented built-in instrument script function "delete_event_mark()".
* Implemented built-in instrument script function "by_marks()".
* Added built-in instrument script int const variables $MARK_1 to $MARK_28.
* Built-in instrument script functions "ignore_event()", "note_off()" and
  "gig_set_dim_zone()" now also accept an array of event IDs as argument
  (i.e. return value of new script function "by_marks()").
* Bumped version (1.0.0.svn53).
