midictrl

midictrl — Get the current value (0-127) of a specified MIDI controller.

Description

Get the current value (0-127) of a specified MIDI controller.

Syntax

ival midictrl inum [, imin] [, imax]
kval midictrl inum [, imin] [, imax]

Initialization

inum -- MIDI controller number (0-127)

imin, imax -- set minimum and maximum limits on values obtained.

Performance

Get the current value (0-127) of a specified MIDI controller.

Warning

midictrl should only be used in notes that were triggered from MIDI, so that an associated channel number is available. For notes activated from the score, line events, or orchestra, the ctrl7 opcode that takes an explicit channel number should be used instead.

Examples

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