## Description

Print the saved values of MIDI controllers from an array to the console or a file.

## Syntax

## Initialization

Sfile -- File name to receive the values. If omitted it writes to the console.

## Performance

kcont -- the array of controls as saved by ctrlsave.

## Examples

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