ctrlinit

ctrlinit — Sets the initial values for a set of MIDI controllers.

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] 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.
