# print

print -- Displays the values init, control, or audio signals.

## Description

These units will print orchestra init-values, or produce graphic display of orchestra control signals and audio signals. Uses X11 windows if enabled, else (or if -g flag is set) displays are approximated in ASCII characters.

## Syntax

print iarg [, iarg1] [, iarg2] [...]

## Initialization

iarg, iarg2, ... -- i-rate arguments.

## Performance

print -- print the current value of the i-time arguments (or expressions) iarg at every i-pass through the instrument.

## Examples

Here is an example of the print opcode. It uses the files print.orc and print.sco.

Example 1. Example of the print opcode.

    /* print.orc */
    ; Initialize the global variables.
    sr = 44100
    kr = 4410
    ksmps = 10
    nchnls = 1

    ; Instrument #1.
    instr 1
      ; Print the fourth p-field.
      print p4
    endin
    /* print.orc */

    /* print.sco */
    ; p4 = value to be printed.
    ; Play Instrument #1 for one second, p4 = 50.375.
    i 1 0 1 50.375
    ; Play Instrument #1 for one second, p4 = 300.
    i 1 1 1 300
    ; Play Instrument #1 for one second, p4 = -999.
    i 1 2 1 -999
    e
    /* print.sco */

Its output should include lines like this:

    instr 1:  p4 = 50.375
    instr 1:  p4 = 300.000
    instr 1:  p4 = -999.000
