Description

Sets the initial values for a set of MIDI controllers.

Syntax

ctrlinit ichnl, ictlno1, ival1 [, ictlno2] [, ival2] [, ictlno3] \
      [, ival3] [,...ival32]

Initialization

ichnl -- MIDI channel number (1-16)

ictlno1, ictlno1, etc. -- MIDI controller numbers (0-127)

ival1, ival2, etc. -- initial value for corresponding MIDI controller number, in the range 0 to 127.

	Note
	If this opcode is to be used with a scaling opcode such as ctrl7 the ival1.. should be 127*(initial-min)/(max-min)

Performance

Sets the initial values for a set of MIDI controllers.

Examples

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

<CsoundSynthesizer>
<CsOptions>
-d
</CsOptions>
<CsInstruments>

sr = 44100
nchnls = 1
0dbfs = 1
	
ctrlinit 1,1,64 ; init control to 64.

instr 1
 kval ctrl7 1,1,0,1  ; read in the range 0-1
 printk2 kval   ; prints 0.50394
endin

</CsInstruments>
<CsScore>
i1 0 1
</CsScore>
</CsoundSynthesizer>
