## outrg

outrg — Allow output to a range of adjacent audio channels on the audio output device

## Description

outrg outputs audio to a range of adjacent audio channels on the audio output device.

## Syntax

    outrg kstart, aout1 [,aout2, aout3, ..., aoutN]

## Performance

kstart - the number of the first channel of the output device to be accessed (channel numbers starts with 1, which is the first channel)

aout1, aout2, ... aoutN - the arguments containing the audio to be output to the corresponding output channels.

outrg allows to output a range of adjacent channels to the output device. kstart indicates the first channel to be accessed (channel 1 is the first channel). The user must be sure that the number obtained by summing kstart plus the number of accessed channels -1 is <= nchnls.

## Examples

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

Its output should include lines like these:

    speaker 1 position 0.000200
    speaker 1 position 0.000400
    speaker 1 position 0.000600
    .....
    speaker 1 position 1.000000
    speaker 2 position 0.000000
    speaker 2 position 0.000200
    ....
    speaker 2 position 0.999800
    speaker 3 position 0.000000
    speaker 3 position 0.000200
    ....
    speaker 3 position 0.999600
    speaker 4 position 0.000000
