print

print — Displays the values init (i-rate) variables.

Description

These units will print orchestra init-values.

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.

[Note] Note

The print opcode will truncate decimal places and may not show the complete value. Csound's precision depends on whether it is the floats (32-bit) or double (64-bit) version, since most internal calculations use one of these formats. If you need more resolution in the console output, you can try printf.

Examples

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

Example 566. Example of the print opcode.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

; p4 = value to be printed.

i 1 0 1 50.375

i 1 1 1 300
; Play Instrument #1 for one second, p4 = -999.

Its output should include lines like this:

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