Description

Initializes the controllers used to create a 21-bit MIDI value.

Syntax

initc21 ichan, ictlno1, ictlno2, ictlno3, ivalue

Initialization

ichan -- MIDI channel (1-16)

ictlno1 -- most significant byte controller number (0-127)

ictlno2 -- medium significant byte controller number (0-127)

ictlno3 -- least significant byte controller number (0-127)

ivalue -- floating point value (must be within 0 to 1)

Performance

initc21 can be used together with both midic21 and ctrl21 opcodes for initializing the first controller's value. ivalue argument must be set with a number within 0 to 1. An error occurs if it is not. Use the following formula to set ivalue according with midic21 and ctrl21 min and max range:

Thanks goes to Rasmus Ekman for pointing out the correct MIDI channel and controller number ranges.
