Hi Axel,

These are two approaches; The first one uses  several predefined

synthdefs - as many as the number of channels you want to deal with.

The second approach generates the synthdef accordingly to the number

of channels needed.

I have added a couple of ideas of how to load soundfiles into a

buffers array as well.

From BufRd help:

warning: if you supply a bufnum of a buffer that has a different

numChannels then [sic] you have specified to the BufRd, it will

fail silently.

I thought Axel was asking how to play only one channel out of a multichannel sound file. So if you have a stereo file and do BufRd.ar(1, ...), you'll get no sound.

At present there is no easy way to load a pre selected channel of a sound file. However you can use PlayBuf or BufRd to play back all the channels, and choose only the channel you need for the output.

stereoSig = BufRd.ar(2, ...);

Out.ar(outbus, stereoSig[0])  // play only the left channel
