scoreline — Issues one or more score line events from an instrument.
Scoreline will issue one or more score events, if ktrig is 1 every k-period. It can handle strings in the same conditions as the standard score. Multi-line strings are accepted, using {{ }} to enclose the string.
“Sin” -- a string (in double-quotes or enclosed by {{ }}) containing one or more score events.
Here is an example of the scoreline opcode. It uses the file scoreline.csd.
Example 790. Example of the scoreline opcode.
See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

You can use string opcodes like sprintfk to produce strings to be passed to scoreline like this:
Sfil = "/Volumes/Bla/file.aif" String sprintfk {{i 2 0 %f "%s" %f %f %f %f}}, idur, Sfil, p5, p6, knorm, iskip scoreline String, ktrig
event, event_i, schedule, schedwhen, schedkwhen, schedkwhennamed, scoreline_i
