scoreline

scoreline — Issues one or more score line events from an instrument.

Description

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.

Syntax

scoreline Sin, ktrig

Initialization

Sin -- a string (in double-quotes or enclosed by {{ }}) containing one or more score events.

Performance

ktrig -- event trigger, 1 issues the score event, 0 bypasses it.

Examples

Here is an example of the scoreline opcode. It uses the file scoreline.csd.

Example 764. 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
