I cannot reproduce this behaviour. $ sox -n poly.wav synth 5 sin 200 sin 300 sin 400 $ sox -n next.wav synth 5 sin 400 sin 600 sin 800 $ sox -M "|sox poly.wav -p pad 1" "|sox next.wav -p pad 1" output.wav This creates a six-channel file with channels ordered as I would expect: channel one from poly.wav, channel two from poly.wav, up to channel three from next.wav. I verified that with listening to $ play output remix 1 $ play output remix 2 $ play output remix 3 $ play output remix 4 $ play output remix 5 $ play output remix 6 What version of SoX are you using? Does it also happen with the current version? Can you please upload two of your multichannel files so that I can reproduce exactly what you are doing?
