4.6.1.5.1 Patterns <patterns/>

Patterns use a simple script language that allows different chord sets or wave files to be strung together with periods of silence. The script language uses the following instructions:

Instruction	Meaning	Example
sampled (n)	Play sampled audio	se.pat.callProg.x.inst.y.type =”sampled” (sampled audio
	file na	file instruction type)
		se.pat.callProg.x.inst.y.value =”3” (specifies sampled
		audio file 3)
chord (n, d)	Play chord set n (d is	se.pat.callProg.x.inst.y.type = “chord” (chord set instruc-
	optional and allows	tion type)
	the chord set ON	se.pat.callProg.x.inst.y.value = “3” (specifies call
	duration to be over-
		progress chord set 3)
	ridden to d millisec-
		se.pat.callProg.x.inst.y.param = “2000” (override ON
	onds)
		duration of chord set to 2000 milliseconds)
silence (d)	Play silence for d	se.pat.callProg.x.inst.y.type = “silence” (silence instruc-
	milliseconds (Rx	tion type)
	audio is not muted)	se.pat.callProg.x.inst.y.value = “300” (specifies silence
		is to last 300 milliseconds)
branch (n)	Advance n instruc-	se.pat.callProg.x.inst.y.type = “branch” (branch instruc-
	tions and execute	tion type)
	that instruction (n	se.pat.callProg.x.inst.y.value = “-5” (step back 5 instruc-
	must be negative and
		tions and execute that instruction)
	must not branch
	beyond the first
	instruction)

a.Currently, patterns that use the sampled instruction are limited to the following format: sampled followed by optional silence and optional branch back to the beginning.

In the following table, x is the pattern number, y is the instruction number. Both x and y need to be sequential. There are three categories of sound effect patterns: callProg (call progress patterns), ringer and misc (miscellaneous).

Attribute	Permitted Values	Interpretation
se.pat.callProg.x.name	UTF-8 encoded	Used for identification purposes in the user inter-
	string	face (currently used for ringer patterns only); for
		patterns that use a sampled audio file which has
		been overridden by a downloaded replacement, the
		se.pat.ringer.x.name parameter will be overridden
		in the user interface by the file names of the wave
		file.
